Program to find the sum and difference of two numbers

Given two Integers A and B, your task is to find the sum and difference of two numbers.

Examples:

Input: A = 4, B = 9
Output: Sum = 13 and Difference = -5
Input: A = -3, B = -2
Output: Sum = -5 and Difference = -1

Approach:

The problem can be solved using arithmetic operators.

Operations on Numbers:

• Addition (+): This operation is used to add the inputs to get the output. For example, when 2 is added to 3 the resultant will be equal to the sum of both the numbers which is equal to 5, (2 + 3 = 5).
• Subtraction (-): This operation is used to subtract the inputs to get the result. For example, when 3 is subtracted by 2 the resultant will be equal to the difference of both the numbers which is equal to 1 (3 – 2 = 1).

Step-by-step algorithm:

• Read A and B from the user
• Calculate the sum: result = A + B
• Calculate the difference: result = A – B
• Display the results.

Below is the implementation of the above approach:

C++

#include <iostream>
using namespace std;

int main()
{
    int A, B;
    A = 4;
    B = 9;
    cout << "Sum of " << A << " and " << B << " = " << A + B
         << endl;
    cout << "Difference of " << A << " and " << B << " = "
         << A - B << endl;
}

Java

public class MainClass {
    public static void main(String[] args) {
        // Declaring and initializing variables A and B
        int A, B;
        A = 4;
        B = 9;

        // Printing the sum of A and B
        System.out.println("Sum of " + A + " and " + B + " = " + (A + B));

        // Printing the difference of A and B
        System.out.println("Difference of " + A + " and " + B + " = " + (A - B));
    }
}

Python3

# Python code
A = 4
B = 9

# Printing the sum of A and B
print(f"Sum of {A} and {B} = {A + B}")

# Printing the difference of A and B
print(f"Difference of {A} and {B} = {A - B}")

C#

using System;

class MainClass
{
    public static void Main(string[] args)
    {
        int A, B;
        A = 4;
        B = 9;

        // Printing the sum of A and B
        Console.WriteLine($"Sum of {A} and {B} = {A + B}");

        // Printing the difference of A and B
        Console.WriteLine($"Difference of {A} and {B} = {A - B}");
    }
}

Javascript

let A, B;
A = 4;
B = 9;

console.log("Sum of " + A + " and " + B + " = " + (A + B));
console.log("Difference of " + A + " and " + B + " = " + (A - B));

Output

Sum of 4 and 9 = 13
Difference of 4 and 9 = -5
