Question

Problem 1: Guess a Number You are writing a program for a number guessing game. For playing "Guess a Number", the program will generate a number for player to guess from within a range specified by the player. The program will take as input the lowest number in the range and the highest number in the range from the player, and then a series of guesses of the form: <n,>n, = n, where n is the number guessed. You can assume the input is always of the form symbol, then a space, then a number. On a successful guess of "=n" the program ends congratulating the player, on an unsuccessful guess the player is informed they are incorrect and the program ends. An example of a player winning the game is shown in Figure 1 and a player losing game in Figure 2. Enter the smallest number to guess: Enter the largest number to guess: 20 Enter your guess (sign + number): > 12 Yes Enter your guess (sign + number): > 16 Yes Enter your guess (sign + number): > 18 Enter the smallest number to guess: Enter the largest number to guess: Enter your guess (sign + number): Yes Enter your guess (sign + number): Enter your guess (sign + number): Enter your guess (sign + number): - 17 Correct, you win!! Figure 1 Run of Guess a Number where the player wins. Incorrect guess, the number was 10, sorry you lose! Figure 2 Run of Guess a Number where the player loses.

Code:

import java.util.Scanner;

public class Main

{

              public static void main(String[] args) {

                  int smallestNumber , largestNumber, number, guess;

                  char symbol;

                             Scanner input = new Scanner(System.in);

                            

                             //take the input from the user for smallest and largest

                             System.out.println("Enter the smallest number to guess:");

                             smallestNumber = input.nextInt();

                            

                             System.out.println("Enter the largest number to guess:");

                             largestNumber = input.nextInt();

                            

                             //generate random number for guessing

                             number = smallestNumber + (int)(Math.random() * ((largestNumber - smallestNumber) + 1));

                            

                             //loop to take guesses from user and act accordingly, assuming the format of guess would be same as given symbol then space and then value

                             while(true){

                               

                             System.out.println("Enter your guess (sign + number)");

                             symbol = input.next().charAt(0);

                            

                             guess = input.nextInt();

                            

                             if(symbol == '>'){

                                 if(number > guess )

                                     System.out.println("Yes");

                                 else

                                     System.out.println("No");

                             }

                             else if(symbol == '<'){

                                   if(number < guess )

                                     System.out.println("Yes");

                                 else

                                     System.out.println("No");

                             }

                             else if(symbol == '=')

                             {

                                 if(number == guess){

                                     System.out.println("Correct, you win!!");

                                 }

                                 else

                                     System.out.println("Incorrect guess, the number was " + number + ", you lose!");

                                     

                                 break;

                             }

                            

                             }

                            

              }

}

===============screens hot of the code=========

Main.java 1 import java.util.Scanner; 3 public class Main public static void main(String[] args) { int smallest Number , largestNumber, number, guess; char symbol; Scanner input = new Scanner(System.in); //take the input from the user for smallest and largest System.out.println("Enter the smallest number to guess:"); smallestNumber = input.nextInt ; System.out.println("Enter the largest number to guess:"); largest Number = input.nextInt(); //generate random number for guessing number = smallestNumber + (int) (Math.random() * ((largestNumber - smallestNumber) + 1)); // Loop to take guesses from user and act accordingly, assuming the format of guess would be same as given symbol then space and then value while(true){ System.out.println("Enter your guess (sign + number)"); symbol = input.next().charAt(); guess = input.nextInt(); if(symbol == '>'){ if(number > guess ) System.out.println("Yes"); else System.out.println("No"); else if(symbol == '<'){ if (number < guess )|| System.out.println("Yes"); else System.out.println("No"); else if(symbol == '=') if(number == guess) { System.out.println("Correct, you win!!"); else System.out.println("Incorrect guess, the number was " + number + ", you lose!"); break; 54 }

Output:

Enter the smallest number to guess: Enter the largest number to guess: 20 Enter your guess (sign + number) > 10 Yes Enter your guess (sign + number) < 17 Yes Enter your guess (sign + number) = 12 Incorrect guess, the number was 11, you lose! ...
