Program to add two variables

After adding two constant values now we are adding two variables.
In this program we are taking two variables a and b of integer type.
And a variable c to store the result of a+b.
Value of a and b will vary according to user input.

Try this program :
/*aim : program to add two variables*/ #include<stdio.h> #include<conio.h> int a,b,c; int main() { printf("Enter two no. : "); scanf("%d%d",&a,&b); c=a+b; printf("sum is %d",c); getch(); }
