In this article we will show you, How to write a simple C program to add two integer values and print the output.
Simple C Program to add Two numbers
This C program let the user to enter two integer values and then add those two numbers and assign the total to variable sum.
CODE

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
/* Simple C Program to add Two numbers */ #include <stdio.h> int main() { int number1, number2, sum; printf(" Enter two integer values \n "); scanf("%d %d", &number1, &number2); sum = number1 + number2; printf(" Sum of the two integer values is %d", sum); return 0; } |
OUTPUT:
ANALYSIS
First we declared three integer values called as number1, number2 and sum
|
1 |
int number1, number2, sum; |
Following statements ask the user to enter two integer numbers, next scanf statement will assign the user entered values to already declare variables number1 and number2.
|
1 2 |
printf(" Enter two integer values \n"); scanf("%d %d", &number1, &number2); |
Next line, we used Arithmetic Operators + to add number1 and number2 and then assigned that total to sum.
|
1 |
sum = number1 + number2; |
Following printf statement will print the sum variable as output (22 + 44 = 66).
|
1 |
printf(" Sum of the two integer values is %d", sum); |
This program worked well while adding two positive integers, How about adding positive and negative integer? Let us see
It worked fine with negative numbers too 🙂
