What are the best practices for function overloading in C++?

Some best practices include keeping the function signatures clear, avoiding ambiguity, and ensuring that overloaded functions have distinct purposes.

Can you give an example of good function overloading?

Sure! For instance, you might overload a function to handle both integers and doubles, like this:

void print(int value) {
    std::cout << "Integer: " << value << std::endl;
}

void print(double value) {
    std::cout << "Double: " << value << std::endl;
}

What should I avoid when overloading functions?

Avoid overloading functions that differ only by return type, as this can lead to confusion and ambiguity in function calls.

Are there any performance considerations with function overloading?

Yes, while function overloading itself doesn't significantly impact performance, excessive overloading can lead to longer compile times and potential runtime overhead due to increased complexity.
