What are function pointers in C?

Can you explain what function pointers are in C?

Function pointers in C are variables that store the address of a function, allowing you to call functions dynamically.

How do I declare a function pointer?

You declare a function pointer by specifying the return type, followed by an asterisk, and the function's parameter types. For example: int (*ptr)(int, int);.

Can you give me an example of using a function pointer?

Sure! Here's a simple example:

#include <stdio.h>

int add(int a, int b) {
    return a + b;
}

int main() {
    int (*funcPtr)(int, int) = add;
    printf("Result: %d\n", funcPtr(2, 3)); // Calls add function
    return 0;
}
