Addition of two numbers In c programming

#include <stdio.h> #include <conio.h> void main() { int num1, num2, sum; clrscr(); printf("Enter first number: "); // Ask the user for two numbers scanf("%d", &num1); printf("Enter second number: "); scanf("%d", &num2); sum = num1 + num2; // Calculate the sum printf("The result is:%d", sum); // Display the result getch(); }

Output

Explanation of the Addition Program

This C program takes two numbers from the user and performs addition. It adds the first and second number and stores the total in a variable named sum.

The program uses simple input and output functions along with the + operator to calculate the final result. It is a perfect example for beginners learning arithmetic operations in C.

What the Program Does

• Asks the user to enter the first number (num1).
• Asks the user to enter the second number (num2).
• Adds both numbers using sum = num1 + num2;.
• Displays the total result on the screen.
• Uses clrscr() to clear the screen (Turbo C specific function).
• Uses getch() to pause the output window.

Example Input

Enter first number: 12
Enter second number: 8

Example Output

The result is: 20

Summary:
This program performs simple addition of two numbers entered by the user. It demonstrates how to use variables, scanf(), printf(), arithmetic operators, clrscr(), and getch() in C.
