What are callbacks in C++?

What are callbacks in C++?

Callbacks in C++ are functions that are passed as arguments to other functions, allowing for custom behavior.

Can you give me an example of a callback in C++?

Sure! Here's a simple example:

#include <iostream>

void myCallback(int x) {
    std::cout << "Callback called with value: " << x << std::endl;
}

void executeCallback(void (*callback)(int), int value) {
    callback(value);
}

int main() {
    executeCallback(myCallback, 5);
    return 0;
}
}

What are the advantages of using callbacks?

Callbacks promote code reusability and flexibility, allowing functions to be customized without modifying their code.

Are there any drawbacks to using callbacks?

Yes, callbacks can lead to complex code and difficulties in debugging, especially with nested callbacks.
