C Program to Add two Numbers

In C programming language you will know how to add two numbers in c language with examples, you need use Integer data type to perform addition task lets us understand adding two number in C .

#include<stdio.h>

void main()
{
int number1, number2, sum;

printf(” Enter first Number = “);
scanf(“%d”,&number1);
printf(” Enter second Number = “);
scanf(“%d”,&number2);
sum=number1+number2;
printf( “%d + %d = %d”,number1,number2, sum);

}

 Output

Enter first Number = 10

Enter Second Number = 25

10+25 = 35

Note

#include<stdio.h>

This is pre processor  header file which includes printf function to print output on screen and scanf  function to take user input from keyboard .

void main()

This is main function from where c program execution starts and void have nothing to return the main in this program.

int number1, number2, sum;

These are integer data type variables number1 will store first value and  number2 store second value

sum will be used to store total of two numbers

printf(” Enter first Number = “);

Message on computer screen to enter first number

scanf(“%d”,&number1);

This statement will take number1 from user and store at this address   &number1

printf(” Enter second Number = “);

Message on computer screen to enter second number

scanf(“%d”,&number2);

This statement will take number2 from user and store at this address   &number2

sum=number1+number2;

Add two number in c formula

printf( “%d + %d = %d”,number1,number2, sum);

This statement will print sum of two numbers

Add two numbers in C Programming

 

Second Example

#include<stdio.h>

int main()
{
int number1=15, number2=10, sum;

sum = number1+number2;

printf( “%d + %d = %d”,number1, number2, sum);

return 0;

}
