Question

We will create a program that will guess a number between 1 and 100 chosen by the user.Your program will be iteratively built in several stages, where each stage focuses on implementing just one type of operation. Each stage will build upon the work from the previous stage. This is known as iterative design, a process that allows us to focus on working on a single, simple task at a time, but the resulting software slowly evolves into something much more complex.

Required Concepts: The final homework requires that you implement the following concepts: 1. Storage operations (store data in program) 2. Output operations (print data to screen) 3. Input operations (get data from user) 4. Selection operations (multiple selection based on player input) 5. Mathematical operations (arithmetic, equality, relational) 6. Repetition operations (loop game logic to model multiple turns) 7. Nested selection operations (validate that user’s selection meets rules requirements) CODE IN JAVA!!

Answer 1

import java.util.Random;
import java.util.Scanner;

public class GuessNumber {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       Random r = new Random();
       //generating random number
       int rand = r.nextInt(100);
       System.out.println("Ranom number generated from 1-100");
       int count = 0;
       while (true) {

           System.out.println("Enter your guess");
           // taking number from user
           int num = sc.nextInt();
           //validating if the given number is in range
           if (num < 0 || num > 100) {
               System.out.println("Number must be between 1-100");
               continue;
           }
           //checking if both are equal
           if (num == rand) {
               System.out.println("Good guess");
               break;
           } else if (num < rand) {
               System.out.println("Low.. try again");
           } else {
               System.out.println("High.. try again");

           }
       }
       sc.close();
   }
}
