C语言写扫雷

用C语言单纯写扫雷不是很难，但是要想第一次输入坐标不被炸死，并且当周围没有雷时自动展开，还是有点难度的：

一共需要九个函数来完成这个代码，分别是：初始化数组，选择难度，打印扫雷棋盘，确定雷的个数，布雷，扫雷，确保第一次不被炸死，没有雷时可以展开。

代码如下：

test.c

#define _CRT_SECURE_NO_WARNINGS 1
#include "game.h"

int  game()
{
    int ret = 0;
    char arr[ROWS][COLS] = {0};
    char show[ROWS][COLS] = {0};
    int i = 0;
    int j = 0;
    int n = 0;
    int s = 0;
    int q = 0;
   Initialize( arr, ROWS, COLS, '0');
   printf("请选择难度:> 1  2  3");
   printf("\n");
   scanf("%d",&n);
   s = select_level(n);
   set_mine( arr,ROW, COL,s) ; 
   Initialize( show, ROWS, COLS, '*');
   display( show, ROW, COL);
   safe_mine( arr,show,ROW,COL);
    display( show, ROW, COL);

    while(1)
    { 
        printf("请输入坐标\n");
        scanf("%d %d",&i,&j);
        Sweep(arr, show, ROW, COL, i, j);
        q = count_show(show, ROW, COL);
        if(s == q )
        {  

            printf("恭喜你，你赢了\n");
            display( show, ROW, COL);
             break;
        }
        if( Sweep(arr, show, ROW, COL, i, j) == 0 )
        {
            printf("你被炸死了\n");
            display( show, ROW, COL);
            printf("布雷图\n");
            display( arr, ROW, COL); 
              break;
        }    
        display( show, ROW, COL);

    }
return 0;
} 

 void menu()
{
    printf("*******************************************\n");
    printf("********       1、play           **********\n");
    printf("********       0、exit           **********\n");
    printf("*******************************************\n");
}
