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
Time Complexity: O(1)
Auxiliary Space: O(1)
