@#include<iostream>

double x=0;
std::cin>>x;
std::cout<<x*x;
return 0;

You are asking about application updating like Firefox, Chrome updaters?

That depends a lot. In general, what you need to do, is to write code that will download the newly built version of your application, and then replace the files that need to be replaced (app executable, libraries, config files etc.).

Or, if you are wise enough to be using Linux, you can leverage distro updaters like apt-get, pacman, etc.
