推荐答案

如果您已正确完成，这应该是完全可以接受的。确保您的标题只能使用标题后卫处理一次。

要么：

This should be perfectly acceptable if you''ve done it correctly. Make sure your header only gets processed once using a header guard.
Either:

#ifndef HEADER_NAME
#define HEADER_NAME
//All your code
#endif

-OR-

-OR-

#pragma once
//code

您的错误表明您的某些标识符未在代码中的任何位置定义（可能是原型不匹配）。如果没有更多信息，很难猜出你的实际问题出现在哪里。

Your error indicates that you have some identifier that isn''t defined anywhere in your code (might be a prototype mismatch). Without more information, it''s kind of hard to guess where your actual problem arises.
