struct road *walk(struct arr *head,int n1,int n2,int d)
{
int d1,i;
struct arr *p1,*p2;
p2=p1=head;
struct road *headc=NULL,*pc;

改为

struct road *walk(struct arr *head,int n1,int n2,int d)
{
int d1,i;
struct arr *p1,*p2;
struct road *headc=NULL,*pc; //2行交换位置
p2=p1=head;

你的是贪吃蛇吧？[Quote=引用 2 楼 huanmie_09 的回复:]
很想帮你改，还是重新给你一个吧，
运行环境tc 2.01

... 干脆来个贪吃蛇吃迷宫的程序算了。
代码长，不方便看。
还好楼主问题已经解决了

恩，这个是贪吃蛇。

把代码放在这个中间，会好看一点，建议！

上楼的哥们儿 你发的程序是解决什么问题的 能描述一下吗
