Pointers to Functions in C

Pointers to Functions in C

Pointers to functions allow you to store and pass around the addresses of functions. This provides flexibility in function invocation and enables dynamic function dispatch.

#include <stdio.h>

int add(int a, int b) {

    return a + b;

}

int subtract(int a, int b) {

    return a - b;

}

int multiply(int a, int b) {

    return a * b;

}

int main() {

    int (*operation)(int, int);  // Pointer to function declaration

    operation = add;             // Assign address of add function

    printf("Addition: %d\n", operation(3, 2));

    operation = subtract;        // Assign address of subtract function

    printf("Subtraction: %d\n", operation(3, 2));

    operation = multiply;        // Assign address of multiply function

    printf("Multiplication: %d\n", operation(3, 2));

    return 0;

}
