Out-of-class overload of unary operators in C++

April 29, 2013
[programming] [c++]

This may sound strange, but it seems that I have never thought about overloading of unary operators in C++, which are not implemented as member functions. It's not like it sounds strange or incorrect, I just never wanted to do it. So, just to be able to say "I did it at least once", lets try it out on a very basic example with overloading of postfix increment operator:

#include <cstdlib>

#include <iostream>

class A

void operator++(const A&, int)
    std::cout << "Overloaded!" << std::endl;

int main(void)
    A a;
    return EXIT_SUCCESS;

The output is easy to guess:


That's it. I don't have anything more to say about it, because the idea of this post is to fix the fact about this simple thing.
