Question

Develop a C++ program with two classes named as “add”, “sub” to perform addition and subtraction of two given numbers and inherit these values to another class named as “remainder” to find the remainder of these values.

Answer 1

Answer:

import java.util.Scanner;

public class Exercise6 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.print("Input first number: ");

int num1 = in.nextInt();

System.out.print("Input second number: ");

int num2 = in.nextInt();

System.out.println(num1 + " + " + num2 + " = " +

(num1 + num2));

System.out.println(num1 + " - " + num2 + " = " +

(num1 - num2));

System.out.println(num1 + " x " + num2 + " = " +

(num1 * num2));

System.out.println(num1 + " / " + num2 + " = " +

(num1 / num2));

System.out.println(num1 + " mod " + num2 + " = " +

(num1 % num2));

}

}

Copy

Sample Output:

Input first number: 125

Input second number: 24

125 + 24 = 149

125 - 24 = 101

125 x 24 = 3000

125 / 24 = 5

125 mod 24 = 5

Sample Solution:

Java Code:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

System.out.println("Input the first number: ");

int n1 = scanner.nextInt();

System.out.println("Input the second number: ");

int n2 = scanner.nextInt();

int sum = n1 + n2;

int minus = n1 - n2;

int multiply = n1 * n2;

int subtract = n1 + n2;

int divide = n1 / n2;

int rnums = n1 % n2;

System.out.printf("Sum = %d\nMinus = %d\nMultiply = %d\nSubtract = %d\nDivide = %d\nRemainderOf2Numbers = %d\n ", sum, minus, multiply, subtract, divide, rnums);

}

}

Copy

Sample Output:

Input the first number:

6

Input the second number:

5

Sum = 11

Minus = 1

Multiply = 30

Subtract = 11

Divide = 1

RemainderOf2Numbers = 1
