C Language Chapter One big job

Use C 's basic language can do some simple game programming in the following example of the flying game

With this simple language we can do these types of sequencing designs by ourselves.

C Language Game program can see, C language is our first programming language, from the computer does not have any programming ability of rookie, to now can read C language program, feel oneself in slowly progress. I think C language is a class of function combination. We can package and modify this program just by modifying some of these conditions.
