本程序代码为C语言解决数据结构（严蔚敏）中关于迷宫的问题。

程序不仅实现迷宫路径查找，还实现文字描述路径功能可以直接粘贴到vc6.0中运行【代码如下】# include <stdio.h> # include <malloc.h> # define null 0typedef struct{int (*base)[2];int (*top)[2];int listlen;}sqlist;int topelem[2]; //栈顶元素void creatstack(sqlist *mazepath); //创建一个存储路径的栈void creatmap(int (*mazemap)[10]); //创建迷宫图纸void printmap(int (*mazemap)[10]);void footprint(int x,int y,int k,int (*mazemap)[10]);int position(int x,int y); //判断是否到终点int passroad(int x,int y,int (*mazemap)[10]);void findpath(int (*mazemap)[10],sqlist *mazepath); //在mazemap当中寻找mazepahtvoid printpath(sqlist *mazepath);void roadinwords(sqlist *mazepath); //文字叙述如何走迷宫void push(int x,int y,sqlist *mazepath); //栈操作void pop(sqlist *mazepath);void gettop(sqlist *mazepath);void main(){sqlist mazepath;creatstack(&mazepath); //创建一个存储路径的栈int mazemap[10][10]={1,1,1,1,1,1,1,1,1,1,1,0,0,1,0,0,0,1,0,1,1,0,0,1,0,0,0,1,0,1,1,0,0,0,0,1,1,0,0,1,1,0,1,1,1,0,0,0,0,1,1,0,0,0,1,0,0,0,0,1,1,0,1,0,0,0,1,0,0,1,1,0,1,1,1,0,1,1,0,1,1,1,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1,1,1,1};// creatmap(mazemap); //创建迷宫图纸printf("迷宫原图为：\n");printmap(mazemap);findpath(mazemap,&mazepath); //在mazemap当中寻找mazepaht printf("走出迷宫图纸为：\n");printmap(mazemap);printf("走出迷宫文字叙述为：\n");roadinwords(&mazepath);// printpath(&mazepath);}void findpath(int (*mazemap)[10],sqlist *mazepath){int x,y,flag=0,k=0,next; //位置是否可通，flag=0通，1墙，2通但不可走x=1;y=1; //获取初始位置push(x,y,mazepath); //起点位置进栈footprint(x,y,6,mazemap);while(flag==0 && k!=162) //flag==1到达终点,0未到达终点{if(passroad(x,y+1,mazemap)==0)push(x,y+1,mazepath),y=y+1,footprint(x,y,6,mazemap);else if(passroad(x+1,y,mazemap)==0)push(x+1,y,mazepath),x=x+1,footprint(x,y,6,mazemap);else if(passroad(x,y-1,mazemap)==0)push(x,y-1,mazepath),y=y-1,footprint(x,y,6,mazemap);else if(passroad(x-1,y,mazemap)==0)push(x-1,y,mazepath),x=x-1,footprint(x,y,6,mazemap);elsefootprint(x,y,2,mazemap),pop(mazepath),gettop(mazepath),x=topelem[0],y= topelem[1];// printmap(mazemap);k++;flag=position(x,y); //判断是否到达终点// printf("flag==%d\n",flag);}}void creatstack(sqlist *mazepath){mazepath->base=(int (*)[2])malloc(120*sizeof(int (*)[2]));mazepath->top=mazepath->base;mazepath->listlen=120;}void push(int x,int y,sqlist *mazepath){**(mazepath->top)=x;*(*(mazepath->top)+1)=y;mazepath->top++;}void pop(sqlist *mazepath){if(mazepath->top!=mazepath->base)mazepath->top--;}void printmap(int (*mazemap)[10]){int (*p)[10];p=mazemap;int i,j;printf(" \n\n\n");for(i=0;i<10;i++){for(j=0;j<10;j++){if(j==0)printf(" ");if(*(*(p+i)+j)==0)printf("▇");else if(*(*(p+i)+j)==1)printf("□");else if(*(*(p+i)+j)==6)printf("★");elseprintf("▇");if(j==9)printf("\n");}}printf("\n\n");}void printpath(sqlist *mazepath){int (*p)[2];p=mazepath->base;while(p!=mazepath->top){printf("x=%d,y=%d\n",**p,*(*p+1));p++;}}void gettop(sqlist *mazepath){int (*p)[2];int (*q)[2];p=mazepath->base;while(p!=mazepath->top){q=p;p++;}topelem[0]=**q;topelem[1]=*(*q+1);}void footprint(int x,int y,int k,int (*mazemap)[10]){if(x<10 && y<10)*(*(mazemap+x)+y)=k;}int position(int x,int y){int flag;if(x==8 && y==8)flag=1;elseflag=0;return(flag);}int passroad(int x,int y,int (*mazemap)[10]) {int num=1;if(x<10 && y<10)num=*(*(mazemap+x)+y);return(num);}void roadinwords(sqlist *mazepath){int x=1,y=1,i=0;int (*p)[2];p=mazepath->base;p++;while(p!=mazepath->top){if(x==**p && y+1==*(*p+1))printf("向右走→→"),x=**p,y=*(*p+1);else if(x+1==**p && y==*(*p+1))printf("向下走→→"),x=**p,y=*(*p+1);else if(x==**p && y-1==*(*p+1))printf("向左走→→"),x=**p,y=*(*p+1);else if(x-1==**p && y==*(*p+1))printf("向上走→→"),x=**p,y=*(*p+1);i++;if(i%3==0)printf("\n");p++;}printf("\n");}。
