Function Declaration and Prototypes
A function prototype tells the compiler about a function before it is used.
int add(int, int);
int main()
{
printf("%d", add(10, 20));
}
int add(int a, int b)
{
return a + b;
}Function prototypes improve program organization and help the compiler detect incorrect function calls.
