How do I use function pointers in C?

Function pointers in C allow you to store the address of a function and call it later. Would you like an example?

Yes, please provide an example of how to declare and use a function pointer.

Sure! Here's a simple example:

#include <stdio.h>

void greet() {
    printf("Hello, World!\n");
}

int main() {
    void (*funcPtr)() = greet; // Declare a function pointer
    funcPtr(); // Call the function using the pointer
    return 0;
}

This code declares a function pointer funcPtr that points to the greet function.

What are the advantages of using function pointers?

Function pointers provide flexibility, allowing you to implement callback functions, create dynamic function calls, and manage arrays of functions.
