C function prototypes 🤖

From the creator

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("\nHello %s", name); printf("\nYou are %d years old", age); }
