What are function pointers in C++?

Function pointers in C++ are pointers that point to the address of a function, allowing dynamic function calls.

Can you give me an example of how to use function pointers?

Sure! Here's a simple example:

#include <iostream>

void greet() {
    std::cout << "Hello, World!" << std::endl;
}

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

What are the advantages of using function pointers?

Function pointers allow for more flexible code, enabling callbacks and dynamic function selection at runtime.

Are there any drawbacks to using function pointers?

Yes, function pointers can make code harder to read and maintain, and they can lead to errors if not used carefully.
