Find Sum of Two Numbers

Problem Statement

Write a program to find the sum of two numbers entered by the user and display the result.

This is one of the most basic and important problems for beginners, as it introduces:

Taking user input
Performing arithmetic operations
Displaying output

Explanation

In this problem:

We take two numbers as input.
Add both numbers using the + operator.
Store the result in a variable.
Print the final sum.

For example, if the input numbers are 10 and 20, their sum will be 30.

Approach

Read two integers from the user
Add them using the addition operator
Display the result

This logic is the same in C, C++, Java, and Python, only the syntax changes.


#include <stdio.h>

int main() {
    int a, b, sum;
    scanf("%d %d", &a, &b);

    sum = a + b;
    printf("%d", sum);

    return 0;
}


#include <iostream>
using namespace std;

int main() {
    int a, b;
    cin >> a >> b;

    cout << a + b;
    return 0;
}


import java.util.Scanner;

public class SumOfTwoNumbers {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int a = sc.nextInt();
        int b = sc.nextInt();

        System.out.print(a + b);
    }
}


a, b = map(int, input().split())
print(a + b)

Input


10 20

Output

Time and Space Complexity

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

💡 Tips for Beginners

Always store the result in a variable for clarity.
Make sure input format matches the code.
Practice this program using different values.
Try extending it to find the sum of three numbers.

Conclusion :

The Find Sum of Two Numbers program is the first step toward learning programming logic. It helps beginners understand input, variables, operators, and output. Mastering this simple problem makes it easier to learn more complex programs in the future.
