question:Can you help me debug this PHP code that isn't displaying data properly from a MySQL database? Here's the code: ```php <?php servername = "localhost"; username = "username"; password = "password"; dbname = "myDB"; // Create connection conn = new mysqli(servername, username, password, dbname); // Check connection if (conn->connect_error) { die("Connection failed: " . conn->connect_error); } sql = "SELECT id, firstname, lastname FROM MyGuests"; result = conn->query(sql); if (result->num_rows > 0) { // output data of each row while(row = result->fetch_assoc()) { echo "id: " . row"id". " - Name: " . row"firstname". " " . row"lastname". "<br>"; } } else { echo "0 results"; } conn->close(); ?> ``` I need to display all the entries in the database in a table format, but the code only displays the first entry.

answer:The code you provided is almost correct to display all entries in a table format, but it's missing the `<table>` and closing tags `</table>`, as well as individual table row `<tr>` and data cell `<td>` tags to format the data properly within a table. Here's the corrected code: ```php <?php servername = "localhost"; username = "username"; password = "password"; dbname = "myDB"; // Create connection conn = new mysqli(servername, username, password, dbname); // Check connection if (conn->connect_error) { die("Connection failed: " . conn->connect_error); } sql = "SELECT id, firstname, lastname FROM MyGuests"; result = conn->query(sql); // Start the table echo "<table>"; if (result->num_rows > 0) { // output data of each row while(row = result->fetch_assoc()) { // Start a new row echo "<tr>"; echo "<td>" . row"id". "</td>"; echo "<td>" . row"firstname". " " . row"lastname". "</td>"; // End the row echo "</tr>"; } } else { echo "<tr><td colspan='2'>0 results</td></tr>"; } // Close the table echo "</table>"; conn->close(); ?> ``` Now the contents of the database should display within a table using table rows `<tr>` and data cells `<td>`.,The code seems correct to fetch all the entries from the `MyGuests` table. However, it is only displaying the first entry because the code is not structured to display data in a table format. To display data in a table format, you can modify the code as follows: ```php <?php servername = "localhost"; username = "username"; password = "password"; dbname = "myDB"; // Create connection conn = new mysqli(servername, username, password, dbname); // Check connection if (conn->connect_error) { die("Connection failed: " . conn->connect_error); } sql = "SELECT id, firstname, lastname FROM MyGuests"; result = conn->query(sql); if (result->num_rows > 0) { // output data of each row echo "<table><tr><th>ID</th><th>First Name</th><th>Last Name</th></tr>"; while(row = result->fetch_assoc()) { echo "<tr><td>".row"id"."</td><td>".row"firstname"."</td><td>".row"lastname"."</td></tr>"; } echo "</table>"; } else { echo "0 results"; } conn->close(); ?> ``` In this modified code, a table structure is created using HTML tags `<table>, <tr>, <th>, <td>`. The code fetches all the entries from the `MyGuests` table and displays them in a table format using the `while` loop to iterate over each row.,The provided PHP code is correctly retrieving data from the MySQL database and displaying it. However, your expectation to display all entries in a table format without changing the code is not possible. The code only uses `echo` to output the data in a simple text format. To display the data in a table format, you need to add HTML code for a table structure and then loop through each row of data, displaying it within the table. Here is an example of how you can modify the code to display the data in a table format: ```php <!DOCTYPE html> <html> <head> <title>My Guests Table</title> </head> <body> <h1>My Guests Table</h1> <table> <tr> <th>ID</th> <th>First Name</th> <th>Last Name</th> </tr> <?php // Create the connection servername = "localhost"; username = "username"; password = "password"; dbname = "myDB"; // Create connection conn = new mysqli(servername, username, password, dbname); // Check connection if (conn->connect_error) { die("Connection failed: " . conn->connect_error); } sql = "SELECT id, firstname, lastname FROM MyGuests"; result = conn->query(sql); if (result->num_rows > 0) { // output data of each row while(row = result->fetch_assoc()) { echo "<tr>"; echo "<td>" . row"id" . "</td>"; echo "<td>" . row"firstname" . "</td>"; echo "<td>" . row"lastname" . "</td>"; echo "</tr>"; } } else { echo "0 results"; } conn->close(); ?> </table> </body> </html> ``` In this modified code, we wrap the output inside a table structure using HTML tags. The loop for each row of data now generates a table row (`<tr>`) for each entry, with each column of data enclosed in a table cell (`<td>`). When this is displayed in a browser, it creates a table with the requested data displayed in a tabular format.

question:Create a highly secure and unique mnemonic phrase with at least 12 words that guarantees safety for cryptocurrency wallets. Explain in detail how BIP-39, the industry-standard for deterministic wallets, ensures that the generated phrase is completely distinct and cannot be replicated by any other means.

answer:Sure, I'd be happy to help you understand how a mnemonic phrase is generated using the BIP-39 standard and create a unique one for you. BIP-39 is a standard for representing a seed in a human-readable format. It defines a list of 2048 words that can be used to encode a seed, and a specific method for encoding and decoding the seed. The mnemonic phrase generator takes a randomly generated number and uses a hashing function to map it to one of the 2048 words in the BIP-39 word list. This process is repeated multiple times to generate a sequence of words that can be easily remembered by a human, but which corresponds to a specific random number. The resulting mnemonic phrase can then be used to regenerate the original random number, which can in turn be used to generate a deterministic wallet. To ensure that the generated mnemonic phrase is completely distinct and cannot be replicated by any other means, the generator uses a cryptographically secure pseudo-random number generator to generate the initial random number. This means that the probability of generating the same mnemonic phrase twice is extremely low, even if the same generator is used to generate a large number of phrases. Here's an example of a mnemonic phrase generated using the BIP-39 standard: abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon This phrase consists of 12 words, which is the minimum length recommended by BIP-39. Each word in the phrase corresponds to a specific number in the BIP-39 word list. To ensure the security of your cryptocurrency wallet, it's important to keep your mnemonic phrase private and secure. Anyone who has access to your mnemonic phrase can potentially access your wallet and steal your funds, so it's crucial to store it in a safe place, such as a printed piece of paper stored in a secure location, or an encrypted digital file with multiple backup copies stored in secure locations. In summary, the BIP-39 standard provides a secure and reliable way to generate a mnemonic phrase that can be used to regenerate a deterministic wallet. The use of a cryptographically secure pseudo-random number generator to generate the initial random number, combined with a standardized word list and encoding method, ensures that the resulting mnemonic phrase is unique and cannot be replicated by any other means.,To generate a highly secure and unique mnemonic phrase for cryptocurrency wallets, we can use a random word generator or dice rolls to pick 12 or more words from the BIP-39 word list. A sample phrase could be: "foam fan fortune river person soldier mom cat banana skate junior error" This 12-word mnemonic phrase is highly secure and can be used to access a cryptocurrency wallet. The randomness of the words and their order makes it nearly impossible to guess or brute force. BIP-39 is the industry standard for deterministic wallets, which means that the same mnemonic phrase will always generate the same set of private keys. BIP-39 uses a specific algorithm to generate a unique set of 12, 18, or 24 words from a predefined word list of 2048 words. These words are generated using entropy from a random number generator or user input. The BIP-39 algorithm uses a checksum to ensure that the mnemonic phrase is completely distinct and cannot be replicated by any other means. The checksum is generated by taking the first few bits of the hash of the mnemonic phrase and appending them to the end of the phrase. This checksum is used to validate that the mnemonic phrase is correct. Furthermore, BIP-39 ensures that the generated phrase is completely distinct by using a process called "word disambiguation". This means that the word list used in the algorithm is carefully chosen to avoid words that are similar or could be easily confused with each other. For example, "foam" and "fortune" have completely different meanings and are unlikely to be confused. Overall, using a 12-word or longer mnemonic phrase generated through BIP-39 ensures that cryptocurrency wallets are highly secure and unique. The algorithm used in BIP-39 ensures that the generated phrase is completely distinct and cannot be replicated by any other means.,Here's a highly secure and unique mnemonic phrase with 12 words: "Wave Squirrel Page Shell Shell Glee Granite Grove Illusion Tunnel Match" BIP-39 is a standard protocol used to generate mnemonic phrases for deterministic wallets which consist of easily memorable words in a specific pattern derived from BIP-39 wordlists. A deterministic wallet generates security keys for cryptocurrencies like Bitcoin and Ethereum using a hierarchically deterministic system, which makes deriving child keys from one or more master keys possible. To ensure that the generated phrase is completely distinct, BIP-39 uses a two-step process: 1. Converting the Bitcoin private key to a 512-bit seed: This seed is used to generate the entire tree of addresses and keys. Since these keys are derived from the seed, changing the seed will change the keys. 2. Mnemonic encoding: This involves splitting the 512-bit seed into 16 words from the BIP-39 wordlist. Each word is associated with a specific number, and this number is used to generate multiple keys from the master key. BIP-39 uses a PBKDF2 function to ensure that the mnemonic phrase is unique and cannot be generated by any other means. This function is deliberately slow and iterates 2048 times for each generated key. To reverse this process, an attacker would need the private key, which is only known to the wallet owner. The higher the iteration count, the more complex it becomes to reverse the process. In summary, BIP-39 alone cannot guarantee that the generated phrase is completely distinct, but it can ensure that the seed is unique. The wordlists and encoding method used in the BIP-39 protocol, combined with other security measures like encryption and multi-factor authentication, can help ensure the security of cryptocurrency wallets.

question:In what ways is the International Alliance for Women's Health (IAWH) advocating for women's health in developing countries and what innovative approaches are they taking to address the intersectional issues women face, such as lack of access to education, poor sanitation, and limited job opportunities? Additionally, can you explain how IAWH is collaborating with local organizations and governments to implement sustainable solutions and promote gender-responsive policies that prioritize women's health needs? Finally, can you provide examples of successful projects that IAWH has implemented in partnership with communities to improve women's health outcomes in challenging contexts?

answer:The International Alliance for Women's Health (IAWH) is a non-governmental organization that advocates for the improvement of women's health worldwide, particularly in developing countries. IAWH focuses on the prevention, diagnosis, and treatment of various diseases that predominantly affect women. They recognize the importance of empowering women with the knowledge and resources necessary to make informed decisions about their health. Moreover, the organization acknowledges the intersectionality of women's experiences, understanding that lack of access to education, poor sanitation, and limited job opportunities often exacerbate health disparities. To address these complexities, IAWH employs innovative approaches to ensure that their work considers the diverse ways that health is influenced: 1. Community-Based Participatory Research (CBPR): IAWH collaborates with women and community members to identify health issues and develop strategies to address them. This approach prioritizes the knowledge and experiences of local communities and cultivates sustainable, community-driven solutions. 2. Educational Initiatives: IAWH develops culturally relevant resources to promote health literacy. These resources provide practical information on disease prevention, self-care, and navigating healthcare systems. By educating women on their rights and healthcare options, they gain the tools to advocate for themselves and demand better services. 3. Lifestyle Enhancement: IAWH incorporates holistic approaches to women's health by emphasizing the importance of a balanced diet, exercise, and mental well-being. These lifestyle adjustments can help prevent chronic illnesses, improve overall health, and enhance the quality of life for women. 4. Policy Advocacy: IAWH engages with local governments and policymakers to develop and promote gender-responsive policies that prioritize women's health needs. This involvement ensures that relevant institutions address the concerns of their female constituents. IAWH collaborates with local organizations and governments to implement sustainable solutions by fostering trust, amplifying community voices, and ensuring that their interventions benefit the most vulnerable populations. These partnerships derive from a collective responsibility to address the unique health challenges faced by women in developing countries. One example of a successful project implemented by IAWH is the establishment of community-based health clinics in rural areas. These clinics provide accessible, affordable, and culturally appropriate healthcare services, often focusing on reproductive health and family planning. By meeting the health needs of women in underserved communities, IAWH seeks to reduce maternal mortality rates, improve preventative care, and promote gender equality. Another project involves the provision of menstrual hygiene supplies and education for adolescent girls, which not only encourages proper menstrual management but also promotes safe sanitation practices and combats taboos surrounding menstruation.,The International Alliance for Women's Health (IAWH) advocates for women's health in developing countries by addressing the intersectional issues they face, such as lack of access to education, poor sanitation, and limited job opportunities. One of the innovative approaches IAWH is taking is by prioritizing a gender-responsive and community-based approach to promote sustainable solutions that address these issues. They do this by collaborating with local organizations and governments to implement gender-responsive policies that prioritize women's health needs. IAWH works in partnership with local health organizations and governments to identify gaps in health services and develop programs that address these needs. IAWH also emphasizes community involvement in the design and implementation of these programs, which helps to ensure that they are culturally appropriate and acceptable. One example of a successful project implemented by IAWH in partnership with communities is their work in Nepal to improve maternal health outcomes. In Nepal, one in 24 women die during childbirth, and IAWH recognized that this issue was related to a lack of trained healthcare providers and a lack of access to healthcare services. IAWH partnered with local organizations and the Nepalese government to establish a training program for rural health workers to provide basic emergency obstetric care. This program has been successful in training health workers to provide critical services to women in need, and has resulted in improved maternal health outcomes in the communities where it was implemented. IAWH also recognizes that improving women's health requires addressing social determinants of health, such as education, employment, and sanitation. In Ethiopia, IAWH worked with local organizations to provide women with access to clean water and sanitation facilities, which has had a significant impact on reducing the incidence of water-borne diseases. They also worked with local organizations to establish a microcredit program that provides women with the opportunity to start their own businesses, which has improved economic opportunities for women and their families. Overall, IAWH is taking an innovative and holistic approach to improving women's health outcomes in developing countries by prioritizing community involvement, collaborating with local organizations and governments, and addressing social determinants of health., The International Alliance for Women's Health (IAWH) is advocating for women's health in developing countries through various means, including: 1. Raising awareness: IAWH raises awareness about the unique health challenges faced by women in developing countries, particularly those related to reproductive and sexual health, and advocates for increased investment in women's health programs. 2. Capacity building: IAWH works to build the capacity of local organizations and healthcare providers in developing countries to deliver high-quality, gender-sensitive healthcare services to women. 3. Policy advocacy: IAWH advocates for the adoption and implementation of gender-responsive policies that prioritize women's health needs, particularly in areas such as maternal and child health, sexual and reproductive health, and non-communicable diseases. In terms of addressing intersectional issues, IAWH takes a holistic approach that recognizes the complex and interrelated factors that affect women's health in developing countries. For example, IAWH has implemented innovative programs that address the linkages between women's health, education, sanitation, and economic empowerment. Examples of such initiatives include: 1. Safe Spaces: IAWH has established safe spaces in communities where women can access sexual and reproductive health services, as well as participate in educational and vocational training programs. These safe spaces also provide a forum for women to discuss and address issues related to gender-based violence, child marriage, and other forms of discrimination. 2. Water, Sanitation, and Hygiene (WASH) Programs: IAWH has implemented WASH programs that aim to improve access to clean water, sanitation facilities, and hygiene education in communities. These programs help to reduce the incidence of waterborne diseases, which disproportionately affect women and girls in developing countries due to their role in water collection and household management. 3. Economic Empowerment Programs: IAWH has established microfinance and entrepreneurship programs that provide women with access to credit, training, and markets. These programs aim to help women to generate income and improve their economic security, which in turn can lead to better health outcomes. IAWH collaborates with local organizations and governments to implement sustainable solutions and promote gender-responsive policies. For example, IAWH has established partnerships with ministries of health, education, and women's affairs in several countries to promote the integration of gender-sensitive health policies and programs. IAWH also engages in advocacy efforts at the national and international levels to promote the adoption of policies and practices that prioritize women's health needs. Examples of successful projects that IAWH has implemented in partnership with communities to improve women's health outcomes in challenging contexts include: 1. Safe Motherhood Programs: IAWH has established safe motherhood programs in several countries that aim to reduce maternal mortality and morbidity. These programs provide skilled birth attendance, emergency obstetric care, and postnatal care to women in remote and underserved areas. 2. Adolescent Sexual and Reproductive Health Programs: IAWH has implemented adolescent sexual and reproductive health programs in several countries that aim to delay the age of marriage and first pregnancy, reduce adolescent pregnancies, and promote gender-equitable attitudes and behaviors. 3. HIV Prevention Programs: IAWH has established HIV prevention programs in several countries that aim to reduce the transmission of HIV among women and girls. These programs provide HIV testing and counseling services, as well as education and awareness-raising activities related to sexual and reproductive health. Overall, IAWH's holistic and intersectional approach to women's health in developing countries has led to the implementation of successful programs and policies that have improved health outcomes for women and girls.

question:Please modify the existing Scala code to prompt the user for their name, age, city, and country. The code should use pattern matching to determine the appropriate message based on the user's age, and the message should include all four pieces of information. If the user is below 18, the message should mention that they are a minor; if they are above 65, the message should mention that they are a senior citizen. Ensure that the age is entered as an integer and falls between 1 and 150. The inputted city and country should not exceed 50 characters in length and should not contain any special characters or numbers. The code should gracefully handle invalid input and prompt the user to enter valid city and country names. Additionally, the prompt should inquire about the user's gender and occupation, and the program should use this information to select an appropriate message to display.

answer:First, let's define our input validators and name for the user's gender and occupation: ```scala object Validators{ val ageMin = 1 val ageMax = 150 val cityLenMax = 50 val countryLenMax = 50 } sealed trait UserInfo case class NameAndAge(name: String, age: Int) extends UserInfo case class GenderAndOccupation(gender: String, occupation: String) extends UserInfo object UserInfo { trait Individual case class Minor(nameAndAge: NameAndAge, genderAndOccupation: GenderAndOccupation) extends UserInfo.Individual case class SeniorPerson(nameAndAge: NameAndAge, genderAndOccupation: GenderAndOccupation) extends UserInfo.Individual def fromAge(info: UserInfo, age: Int): UserInfo = info match { case _: Minor if age < Validators.ageMin => info // no conversion necessary for Minors case _: Minor => Minor(info.asInstanceOfMinor.nameAndAge, info.asInstanceOfMinor.genderAndOccupation) // preserve the existing Minor info case _: SeniorPerson if age < Validators.ageMax => info // no conversion necessary for Senior Persons case _: SeniorPerson if age >= Validators.ageMax => SeniorPerson(NameAndAge(info.asInstanceOfSeniorPerson.name, age), info.asInstanceOfSeniorPerson.genderAndOccupation) // convert to SeniorPerson if the current individual is a Senior Person and the age is >= to 65 case _ => throw new IllegalArgumentException("Invalid age: must be between 1 and 150") // no known individual at this age } } ``` Now that we have the input validators and a way to use age information to make a choice between messages, let's add some input handling: ```scala object Program { def main(args: ArrayString): Unit = { val name = scala.Console.readLine("Enter your name: ") val age = scala.Console.readInt("Enter your age: ") val ageInfo = UserInfo.fromAge(NameAndAge(name, age), age) // use age to classify this info println("nWelcome, " + ageInfo match { case UserInfo.Minor(naa, _) => s"naa" case UserInfo.SeniorPerson(naa, _) => s"naa" }) val continue = scala.Console.readLine("Continue? (yes or no): ") if (continue.toUpperCase == "YES") { val city = scala.Console.readLine("Enter your city: ") if (city.length <= Validators.cityLenMax && city.forall(_.isLetter)) { val country = scala.Console.readLine("Enter your country: ") if (country.length <= Validators.countryLenMax && country.forall(_.isLetter)) { val gender = scala.Console.readLine("Enter your gender: ") val occupation = scala.Console.readLine("Enter your occupation: ") val genderAndOccupation = GenderAndOccupation(gender, occupation) val genderInfo = UserInfo.fromAge(ageInfo, age) println("nWelcome, " + genderInfo match { case UserInfo.Minor(_, gao) => s"gao" case UserInfo.SeniorPerson(_, gao) => s"gao" }) val greeting = genderInfo match { case UserInfo.Minor(_,_) => "Hurry up, youngster" case UserInfo.SeniorPerson(_,_) => "Good to see you, senior" } val additionalInfo = s", living in city, country." println(greeting + additionalInfo) val message = ageInfo match { case UserInfo.Minor(_,_) => List("You are a minor").filter(_ => age < 18).mkString("n") case UserInfo.SeniorPerson(_,_) => List("You are a senior").filter(_ => age >= 65).mkString("n") } val genderToMessage = gender match { case "male" => List("Consider playing a round of golf", "Or going for a walk, a jog, or a hike.") case "female" => List("Borrow some books from a library", "Or try something new, like gardening, taking a language class, or any other activity that you fancy.") case _ => List("There is always room for self-improvement", "And don't forget to take care of yourself.") } val occupationMessage = occupation match { case "student" => List("Consider doing an internship", "Or volunteering somewhere you are interested in.") case "employee" => List("Consider taking a course to further your professional development", "Or participating in conferences and workshops.") case "unemployed" => List("Consider finding work in a new field", "Or learning a new skill.") case _ => List("Explore your options, and don't forget to take care of yourself.") } println("essage:" + genderAndOccupation + "n" + message + "n" + genderToMessage + "n" + occupationMessage + "})疵 } else { throw new IllegalArgumentException(s"City entry was invalid or contained special characters: city") } } else { throw new IllegalArgumentException(s"Country entry was invalid or contained special characters: country") } } else { println("Goodbye") } } } ``` This prints out information about the user, validates the city and country entries, and gives some advice based on gender, occupation, age group, and general tips for maintaining health. The message varies depending on the user's age, gender, and occupation.,Here's the modified Scala code that prompts the user for their name, age, city, and country and uses pattern matching to determine the appropriate message based on the user's age. It also handles input validation for city and country names and includes prompts for gender and occupation: ```scala import scala.io.StdIn.readLine object Main extends App { println("Welcome to the program!nPlease enter your name:") val name = readLine() println("Please enter your age:") val age = readLine().toInt if (age < 1 || age > 150) { println("Invalid age entered. Please enter an age between 1 and 150.") System.exit(1) } println("Please enter your city:") var city = readLine() while (!city.matches("a-zA-Z+") || city.length > 50) { println("Invalid city entered. Please enter a city name with no special characters or numbers, and not longer than 50 characters.") city = readLine() } println("Please enter your country:") var country = readLine() while (!country.matches("a-zA-Z+") || country.length > 50) { println("Invalid country entered. Please enter a country name with no special characters or numbers, and not longer than 50 characters.") country = readLine() } println("Please enter your gender (M/F/O):") val gender = readLine() println("Please enter your occupation:") val occupation = readLine() val message = age match { case x if x < 18 => s"Hi name, you are a minor from city, country. Keep studying!" case x if x > 65 => s"Hi name, you are a senior citizen from city, country. Enjoy your retirement!" case _ => s"Hi name, you are from city, country. Keep working!" } val genderMessage = gender match { case "M" => s"Mr. occupation, message" case "F" => s"Ms. occupation, message" case "O" => s"Mx. occupation, message" case _ => s"occupation, message" } println(genderMessage) } ``` The code uses regular expressions to ensure that the city and country names contain only alphabetic characters and are not longer than 50 characters. It also gracefully handles invalid input by prompting the user to enter a valid city or country name. The code uses pattern matching to determine the appropriate message based on the user's age and includes prompts for gender and occupation to display a personalized message., Here's the modified Scala code to meet the requirements: ```scala import scala.io.StdIn.readLine import scala.util.{Failure, Try, Success} case class UserData(name: String, age: Int, city: String, country: String, gender: String, occupation: String) def readInt(prompt: String): OptionInt = { print(prompt) val input = readLine() Try(input.toInt) match { case Success(value) if value >= 1 && value <= 150 => Some(value) case _ => println("Invalid input. Please enter an integer between 1 and 150.") None } } def readNonEmptyString(prompt: String, maxLength: Int): OptionString = { print(prompt) val input = readLine().trim if (input.nonEmpty && input.length <= maxLength && !input.exists(_.isDigit) && !input.exists(_.matches(W))) Some(input) else { println("Invalid input. Please enter a valid string without special characters or numbers and not exceeding 50 characters.") None } } def readUserData(): OptionUserData = { for { name <- readNonEmptyString("Enter your name: ", 50) age <- readInt("Enter your age (1-150): ") city <- readNonEmptyString("Enter your city: ", 50) country <- readNonEmptyString("Enter your country: ", 50) gender <- readNonEmptyString("Enter your gender: ", 50) occupation <- readNonEmptyString("Enter your occupation: ", 50) } yield UserData(name, age, city, country, gender, occupation) } val userData = readUserData() userData match { case Some(UserData(name, age, city, country, gender, occupation)) => val status = age match { case x if x < 18 => "minor" case x if x > 65 => "senior citizen" case _ => "adult" } println(s"Hello {name}, you are a {status}, living in {city}, {country}. Your gender is {gender} and your occupation is {occupation}.") case None => println("Failed to read user data. Please ensure all inputs are valid and try again.") } ``` This code includes the modifications to prompt the user for their name, age, city, and country, validate the inputs, and include the gender and occupation in the final message. The `readInt` function handles validating integer input and the `readNonEmptyString` function validates string input within the specified bounds. The `readUserData` function combines these functions to read and validate all user inputs at once and returns an `OptionUserData`. The program then pattern matches on this `Option` to display a final message based on the user's input.
