C Function Pointers

Store references to executable functions and implement callback mechanisms.

❮ Previous Next ❯

Function pointers point to executable code rather than data. They allow passing functions as arguments to other functions (callbacks) and implementing dispatch tables.

Key Takeaways: C Function Pointers

Mastering C Function Pointers helps you write clean and reliable C code. Follow standard conventions, test edge cases, and keep logic simple. Try running the code example below and complete the exercises to build confidence.

C Function Pointers Code Example

#include <stdio.h>

int multiply(int a, int b) { return a * b; }

int main() {
    int (*op)(int, int) = multiply;
    int result = op(6, 7);
    printf("Product via function pointer: %d\n", result);
    return 0;
}

Output

Product via function pointer: 42
