The Centers of a Triangle
Well, this is an old program I've implemented using C++ and the SDL library (version 1) when I started learning C++ several years ago.
I think I could have some issues understanding parts of the code I've written myself, and sometimes in the future I might extend these instructions to include the steps to compile it from scratch, for the moment, it's up to you to find out how to compile it, if you're interested :)
Cheers!
Francesco
