我是大一新生，自己看了看书，水平有限。希望各位高手能够详细的指点。十分感谢！
程序已经放出来了，我想制作一个模仿ATM的程序。
question one:查找问题(已解决)
考虑到实际，必须保护用户名和密码的安全。所以我选择用类来做。可是在检查密码是否正确遇到了问题。我想设一个成员函数CHECK收到用户名和密码后，可以调出正确密码和输入密码进行比较，通过返回0和1值判断是否可以继续程序。可是在调用户名时，发现，类只是个模子，不可以分配空间，怎样可以使类的内部函数具有查找数据的功能是我十分疑惑的地方。
question twe:隐身问题(已解决)
在输入密码时，怎样实现隐身功能？就是，怎样使输入时在屏幕显示“****”而不显示真实的密码？
question three:菜单引导问题(已解决)
教科书上说GOTO不要经常使用，不利于可读性。可是像在原程序中菜单部分的引导除了GOTO，还可以用什么方法可以实现呢？
