SDL tutorial 10 - snake game GUI (part 2) - example program 5

In this tutorial we'll write a GUI for the snake game, we've written earlier.
SDL is a cross-platform free-source library which allows you to draw to the screen (so make graphical programs), we'll make 2D games with it, but it can make 3D render as well, if you use it with OpenGL.

The ncurses version of the snake game (for Linux only, this is the original source, I started the work):

Compile: g++ snake.cpp main.cpp -lncurses


The SDL version (this can be compiled almost any platform, included Linux, MacOS, Windows...):

If you download the SDL version VERY IMPORTANT to put a air.ttf (true type font) beside the runnable (binary file), else the program just collapse (RTE).
Compile:
On Windows the compile works the same way as I showed you in the SDL tutorial 0, in the project/properties-project settings-project's build option-linker settings you have to add -lSDL_ttf
Linux:
g++ snake.cpp main.cpp -lSDL -lSDL_ttf
