这个程序还是有问题
这儿应该改一下
int ACCOUNT::chaxun(unsigned long id,unsigned int pw)
{
     if(check(id,pw))
         return ballance;---------- 改为return error
     else
     {
         cout << "here" << endl;
         return error;-----------   改为 return ballance
     }
}
这样就好了。
要不然程序刚好是反的
很谢谢你呀！！
辛苦了。。

自己调试一下程序，很多程序很容易改正，你的程序基本上正确啦。

调用check（）函数判断上逻辑有问题，已帮你改正。另外像while（C！=4）写错太不应该，学会debug自己的code
