不用visual studio 编译 strcmp()不能用我这个编译
我用的Dev-c++能编译

strcmp是比较两个字符串。
拷贝字符串应该用strcpy
比如构造函数，用strcpy拷贝name_user到fullname中，应该这样写：

bank::Stack::Stack(const char* name_user, const char* name_acount, unsigned long money)
{
    strcpy(fullname, name_user);
    strcpy(account, name_acount);
    deposit_temp = money;
}
