C language to achieve the maze game

Dark clouds Teacher's words: Learning to detect keyboard information, Yu Wenbiao classmate Classroom made a keyboard in the screen up and down to move a star program.

The teacher gave a few students the idea of the Maze game, Peng Bo students next class will do a good maze game out, wonderful!

The idea is clear, the code is concise, the annotation is clear, only everybody learns.

At the same time he also implemented a simple push box game, is a quick program.
