Lab 1 Mad Lib Loopsmad Libs Are Activities That Have A Person Prov

Write a program that takes a string and integer as input, and outputs a sentence using those items as below. The program repeats until the input string is quit 0. Ex: If the input is: apples 5 shoes 2 quit 0 the output is: Eating 5 apples a day keeps the doctor away. Eating 2 shoes a day keeps the doctor away. Note: This is a lab from a previous chapter that now requires the use of a loop.

The purpose of this program is to simulate a Mad Lib activity by repeatedly requesting user inputs comprising words and numbers, constructing humorous or unexpected sentences based on these inputs, and continuing this process until the user inputs a termination signal ("quit 0"). This exercise emphasizes control flow with loops in programming and string handling capabilities.

Introduction

Mad Libs are popular word game activities where players contribute various parts of speech—such as nouns, verbs, and adjectives—that are inserted into a pre-written story template, resulting in amusing or nonsensical stories (Anthony et al., 2019). Implementing a Mad Lib program as described enhances understanding of fundamental programming concepts such as input handling, loops, string processing, and conditionality. The challenge is to design a loop that continues prompting for input until a specific termination condition is met, then constructs and displays output dynamically based on the user input.

Implementation of the Mad Lib Program

The program begins by initializing necessary variables, including a loop control variable. Within the loop, the program prompts the user to enter a string and an integer. This input is processed to construct a sentence following a predefined template: "Eating [number] [word] a day keeps the doctor away." The program displays this sentence for every valid input pair. When the user inputs "quit 0," the loop terminates, ending the program.

The key logic involves the continuous reading of user input, parsing the input, and evaluating whether the input is the termination command. If not, the program proceeds with constructing and displaying the sentence; if yes, it exits gracefully. The implementation utilizes a while loop, string comparison methods, and console input/output functions—all fundamental in procedural programming languages (Gaddis, 2018).

Sample Implementation in Java



import java.util.Scanner;


public class MadLibLoop {


public static void main(String[] args) {


Scanner scanner = new Scanner(System.in);


String inputWord;


int inputNumber;


String userInput;


while (true) {


System.out.println("Enter a word and a number, or 'quit 0' to stop:");


userInput = scanner.nextLine().trim();


// Check for termination condition


if (userInput.equalsIgnoreCase("quit 0")) {


break;


}


String[] inputs = userInput.split("\\s+");


if (inputs.length != 2) {


System.out.println("Invalid input. Please enter a word and a number.");


continue;


}


inputWord = inputs[0];


try {


inputNumber = Integer.parseInt(inputs[1]);


} catch (NumberFormatException e) {


System.out.println("Invalid number. Please try again.");


continue;


}


// Output the constructed sentence


System.out.printf("Eating %d %s a day keeps the doctor away.%n", inputNumber, inputWord);


}


System.out.println("Program terminated.");


scanner.close();


}


}

Conclusion

This implementation effectively demonstrates the use of loops for repeated user interaction, conditional statements for exit conditions, and string handling for dynamic sentence construction. Such exercises are fundamental in developing robust and user-friendly console applications. Extending this program could involve adding error handling, supporting multiple sentences, or integrating graphical user interfaces (Gaddis, 2018).
