C语言编简单的扫雷

条件 随机布置10颗雷
存在问题 1. 布雷的时候有时候是9颗 2. 显示雷数目的时候 最右侧显示不正确 求大神指正

//实验一 编写程序，完成"地雷游戏"的设计。
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
void main()
{
srand(time(NULL));
int a[9][9]={0};
int n,i,j;
for(n=0;n<10;n++)
{i=rand()%9;
j=rand()%9;
if(a[i][j]='*')
continue;
a[i][j]='*';
}
for(i=0;i<9;i++)
{for(n=0;n<9;n++)
if(a[i][n]=='*')printf(" *");
else printf("%3d",a[i][n]);
printf("\n");
}
printf("扫雷输出图\n");
int A,B;
for(i=0;i<9;i++)
{ for(n=0;n<9;n++)
if(a[i][n]!='*')
{for(A=i-1;A<=i+1;A++)
for(B=n-1;B<=n+1;B++)
if(a[A][B]=='*' )
a[i][n]++;

}
}
for(i=0;i<9;i++)
{for(n=0;n<9;n++)
if(a[i][n]=='*')printf(" *");
else printf("%3d",a[i][n]);
printf("\n");
}
}
