自己写的扫雷程序~请大家帮忙看一下有没有更好的写法？

#include<iostream>
#include<ctime>
using namespace std;
int iValue(int iROW , int iCOL);
#define ROW          9    // 行数
#define COL           9    // 列数
#define BOMBNUMS  30    // 雷数

    unsigned iBombNO = 0;
    srand( time(0) );
    int iTmpRow,  iTmpCol;   //行、列位置
    while ( iNum < BOMBNUMS )
