C program to add two numbers: This c language program perform the basic arithmetic operation of addition on two numbers and then prints the sum on the screen. For example if the user entered two numbers as 5, 6 then 11 (5 + 6) will be printed on the screen.
C programming code
#include<stdio.h>
int main()
{
int a, b, c;
printf("Enter two numbers to add\n");
scanf("%d%d",&a,&b);
c = a + b;
printf("Sum of entered numbers = %d\n",c);
return 0;
}
Output of program:
In the expression (c = a + b) overflow may occur if sum of a and b is larger than maximum value which can be stored in variable c.
Addition without using third variable
#include<stdio.h>
main()
{
int a = 1, b = 2;
/* Storing result of addition in variable a */
a = a + b;
/** Not recommended because original value of a is lost
* and you may be using it somewhere in code considering it
* as it was entered by the user.
*/
printf("Sum of a and b = %d\n", a);
return 0;
}
C program to add two numbers repeatedly
#include <stdio.h>
int main()
{
int a, b, c;
char ch;
while (1) {
printf("Inut two integers\n");
scanf("%d%d", &a, &b);
getchar();
c = a + b;
printf("(%d) + (%d) = (%d)\n", a, b, c);
printf("Do you wish to add more numbers (y/n)\n");
scanf("%c", &ch);
if (ch == 'y' || ch == 'Y')
continue;
else
break;
}
return 0;
}
Output of program:
Inut two integers
2 6
(2) + (6) = (8)
Do you wish to add more numbers (y/n)
y
Inut two integers
2 -6
(2) + (-6) = (-4)
Do you wish to add more numbers (y/n)
y
Inut two integers
-5 3
(-5) + (3) = (-2)
Do you wish to add more numbers (y/n)
y
Inut two integers
-5 -6
(-5) + (-6) = (-11)
Do you wish to add more numbers (y/n)
n
Adding numbers in c using function
#include<stdio.h>
long addition(long, long);
main()
{
long first, second, sum;
scanf("%ld%ld", &first, &second);
sum = addition(first, second);
printf("%ld\n", sum);
return 0;
}
long addition(long a, long b)
{
long result;
result = a + b;
return result;
}
