 **Canvas++** is a very simple graphics library contained in single header file. It's purpose is to make teaching of C++ more colorful and funny for kids and students. The main idea is to wrap windows API calls into simple interface. You can start drawing next after "Hello world" example - just declare Window variable and call method draw() to start drawing.
