What are advanced callbacks in C++?

Can you explain what advanced callbacks are in C++?

Advanced callbacks in C++ refer to techniques that allow functions to be passed as arguments, enabling more flexible and reusable code.

How do I implement a callback function in C++?

To implement a callback in C++, you can use function pointers or std::function along with lambda expressions for more flexibility.

Can you give me an example of using a callback with a lambda?

Sure! Here's a simple example:

#include <iostream>
#include <functional>

void process(int value, std::function<void(int)> callback) {
    callback(value);
}

int main() {
    process(5, [](int x) { std::cout << "Value: " << x << std::endl; });
    return 0;
}

What are the advantages of using callbacks?

Callbacks promote code reusability, allow asynchronous programming, and help in decoupling components, making your code cleaner.
