这是一个控制台的贪吃蛇 比较简单
只要楼主了解几个API函数就可以 至于算法 有好多 我这个不怎么样
我建议用链表来表示蛇体 下面是我的一个snake 类 函数体没给 楼主自己想吧
struct node
{node* pre;<br> Cpoint point;<br> node* next;<br>};
node::node()
{ point(0,0);
pre=NULL;
next=NULL;
};

class snake
{ private:
node* snakehead;
node snakebody[100];
int length
int direction;
public:
void go();
bool fail();
void textout();
}
