小弟初学C语言，写了个寻找迷宫出口的“程序”，写完程序后自己感觉很乱，又无从下手，所以贴上来望高手指点一下。。（改成这样行吗斑竹？）

#include "stdio.h"
#include "stdlib.h"
#define col 10
#define row 10
#define nodes 100
int map[col][row]={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,

1,0,1,1,1,0,0,0,0,1,

typedef struct

typedef struct

}stack;
seater strpos,endpos,curpos;
stack *router;

void init();
int pass();
void printfoot();
void push();
void nextstep();

void roadprint();

void main()
{

return 1;
else

}
void printfoot()
{

}

void push()
{

}

{

curpos.dir=1;

}

{

switch(curpos.dir)
{
case 1:curpos.x++;break;
case 2:curpos.y--;break;
case 3:curpos.x--;break;
case 4:pop();break;
default :printf("error direction!\n");
}
curpos.dir=1;

}
void pop()
{
router->seat[router->top--];
curpos=router->seat[router->top];
changedir();
}
void roadprint()
{
for(int i=0;i<=router->top;i++)
{
printf("seat:%d,%d dir:%d top%d\n",router->seat[i].x,router->seat[i].y,router->seat[i].dir,router->top);
}
}

还有一个计算表达式的，由于能力有限，暂时还没有支持负数跟小数点。。请大家批批
支持格式如：3*(9-6)+9/7

以后客气可以~卖乖的话就不要说了（你别生气），只是很多人看了会不舒服

厉害!

没有卖乖啊，我是学C#起步的，现在发现学那个根本走不远 所以我想学C语言把基础打好，感觉自己用C语言写的程序很乱。所以想请大家指点一下的嘛

这。。。。。。。。。。
我被这题头都搞大了，你却。。。。。。。。

没有人指点我一下啊
