1、贪吃蛇源程序 本程序为贪吃蛇游戏,想必大家都玩过这个游戏,程序源代码用TC2.0编译通过,需要图形驱动文件的支持,在TC2.0的集成环境中有.本程序利用数据结构中的链表,来将蛇身连接,同时当蛇吃到一定数目的东西时会自动升级,及移动速度会加快,程序会时刻将一些信息显示在屏幕上,包括所得分数,要吃多少东西才能升级,并且游戏者可以自己手动选择游戏级别,级别越高,蛇的移动速度越快.另外,此游戏可能与CPU的速度有关系.源代码如下:*/*COMMENTS*/* snake_game.c */* it is a game for entermainment. */* in the begin,there
2、is only a snake head,and it will have to eat food */* to become stronger,and it eat a piece of food each time,it will */* lengthen its body,with the number of food the snake eats going up,it */* will become long more and more,and the score will goes up also. */* there is always useful information du
