Question

2.20 TEST 2: the worst calculator ever Input

Prompt the user for 2 integers. Enter an integer: 5 Enter another integer: 2 Processing Modify the first integer by adding 1 to it and save the new value into a variable called modified_int1. Modify the second integer by subtracting 1 from it and save the new value into a variable called modified_int2. Compute the sum, difference, product, quotient, and exponentiation of modified_int1 and modified_int2 and save each into a variable. Print a warning message informing the user that this calculator is not to be trusted. Print the original numbers, the operations, and the new results (as shown below).

Output

Enter an integer: 5

Enter another integer: 2

WARNING: These results are probably wrong!!!

5 + 2 = 7

5 - 2 = 5

5 * 2 = 6

5 / 2 = 6

5 ^ 2 = 6

WorstCalculator.java

import java.util.Scanner;

public class WorstCalculator {
   public static void main(String[] args) {
       // Scanner class object to get the input from user
       Scanner input=new Scanner(System.in);
       System.out.print("Enter an integer: ");
       int integer1=input.nextInt(); // accept first integer
       System.out.print("Enter another integer: ");
       int integer2=input.nextInt(); // accept second integer
       // Modify the first integer by adding 1 to it
       // and save the new value into a variable called modified_int1
       int modified_int1=integer1+1;
       // Modify the second integer by subtracting 1 from it
       // and save the new value into a variable called modified_int2
       int modified_int2=integer2-1;
       System.out.println("\nWARNING: These results are probably wrong!!!");
       // calculate and print results
       System.out.println(integer1+" + "+integer2+" = "+(modified_int1+modified_int2));
       System.out.println(integer1+" - "+integer2+" = "+(modified_int1-modified_int2));
       System.out.println(integer1+" * "+integer2+" = "+(modified_int1*modified_int2));
       System.out.println(integer1+" / "+integer2+" = "+(modified_int1/modified_int2));
       System.out.println(integer1+" ^ "+integer2+" = "+((int)Math.pow(modified_int1, modified_int2)));
       input.close(); // close Scanner object
   }
}
