C Program To Add Numbers using Function

Here we will write a Program to add two numbers using Function. In this case Function is of type "Takes Nothing Returns Something" Which means the function doesn't take any argument  from the main function but returns a value.  

#include<stdio.h>

 
int add(void);         // Function Declaration

int main()
{
   int sum;
   sum=add() ;        // Function Calling

     
   printf("Sum= %d\n,sum);
   return 0;
}


int add()           //Function Definition
{
   int a,b,c;
   printf("Give the two nos.  : \n");
   scanf("%d%d",&a,&b);
   c=a+b;
   return c;
}
