C function prototypes tutorial example explained
#C #function #prototype
void hello(char[], int); //function prototype
int main()
{
// function prototype
// WHAT IS IT?
// Function declaration, w/o a body, before main()
// Ensures that calls to a function are made with the correct arguments
// IMPORTANT NOTES
// Many C compilers do not check for parameter matching
// Missing arguments will result in unexpected behavior
// A function prototype causes the compiler to flag an error if arguments are missing
// ADVANTAGES
// 1. Easier to navigate a program w/ main() at the top
// 2. Helps with debugging
// 3. Commonly used in header files
char name[] = "Bro";
int age = 21;
hello(name, age);
return 0;
}
void hello(char name[], int age)
{
printf("
Hello %s", name);
printf("
You are %d years old", age);
}
