大家好，我是一个菜鸟，现在正在学习数据结构，希望大家指点我，我编写了一个走迷宫的程序，希望大家指点。源程序如下：（可以动态实现）
#include"time.h"
#include "stdio.h"
#include "graphics.h"
#include "conio.h"
#define null 0
int a[11][15]={ , /定义迷宫，这是我们课程设计，所以就用老师给的了/
, /0代表墙，1代表可以通行/
,
,
,
,
,
,
,
,
};
strUCt moving /定义走动方向/
{int x;
int y;
}move[9]=,,,,,,,,};
typedef struct Position *PPosition;
struct Position /定义结构体/
{
int x;
int y;
int direction;
PPosition link;
};
struct LinkPosition /引入一层封装，其实就是好定义空栈罢了/
{
PPosition top;
};
typedef struct LinkPosition *PLinkPosition;
PLinkPosition createEmptyPosition(void) /建立空栈/
{
PLinkPosition plposition;
plposition=(PLinkPosition)malloc(sizeof(struct LinkPosition));
plposition->top=null;
return(plposition);
}
void push(PLinkPosition plposition,int x,int y) /压栈/
{
PPosition p;
p=(PPosition)malloc(sizeof(struct Position));
p->x=x;
p->y=y;
p->direction=1;
p->link=plposition->top;
plposition->top=p;
}
void pop(PLinkPosition plposition) /弹栈/
{
PPosition p;
p=plposition->top;
plposition->top=plposition->top->link;
free(p);
}
int judge(PLinkPosition plposition) /判定这个位置是不是栈中已有的/
{int m,n;
PPosition p;
m=plposition->top->x;
n=plposition->top->y;
p=plposition->top->link;
while(p!=null)
{if(p->x!=mp->y!=n)p=p->link;
else
{return(0);
break;
}
}

}
