int total = 0; //Global Declaration
int sum(int, int); //Function Declaration
int main() //Main Function
{
printf("Basic Program \n");
total = sum(1,5);
printf("Sum = %d \n", total);
return 0;
}
int sum(int a, int b) //User Defined Function
{
return a + b; //Function Definition section
}
Output:
Basic Program
Sum = 6
