乘法而不是指针声明 [英] Multiplication instead of pointer declaration
问题描述
我有以下问题：
MyClass.h
---- -----------
class MyClass {};
此类包含在另一个头文件中的某个位置：
Foo.h
--------
#include" MyClass.h" ;
class Foo {
MyClass * bar;
}
很遗憾，这似乎不起作用。我正在使用Visual Studio
2005并且它提供了以下错误：
错误C2143：语法错误：缺少'';''之前''' *''
错误C4430：缺少类型说明符 - 假设为int。注意：C ++不支持
支持default-int
错误C4430：缺少类型说明符 - 假设为int。注意：C ++不支持
支持default-int
问题出在哪里。
关于该项目的更多事实：它是MS Windows的COM DLL使用
ATL，预编译头文件打开。
欢迎任何解决问题的方法或帮助:)
谢谢，
Stefan Weber
Hi,
I have the following problem:
MyClass.h
---------------
class MyClass {};
This class is included somewhere in another header file:
Foo.h
--------
#include "MyClass.h"
class Foo {
MyClass* bar;
}
Unfortunately, this does not seem to work. I''m using Visual Studio
2005 and it provides the following error:
error C2143: syntax error : missing '';'' before ''*''
error C4430: missing type specifier - int assumed. Note: C++ does not
support default-int
error C4430: missing type specifier - int assumed. Note: C++ does not
support default-int
Obviously, VS does not recognize the type properly, but I can''t see
where the problem is.
Some more facts about the project: It''s a COM DLL for MS Windows using
ATL, precompiled headers are turned on.
Any solution or help to track down the problem is welcome :)
Thanks,
Stefan Weber

Hi,
I have the following problem:
MyClass.h
---------------
class MyClass {};
缺少包含警卫。
Missing include guards.
此类包含在另一个头文件中的某个位置：
Foo.h
--------
#include" MyClass.h"
class Foo {
MyClass * bar;
}
This class is included somewhere in another header file:
Foo.h
--------
#include "MyClass.h"
class Foo {
MyClass* bar;
}
缺少分号。

答：因为它弄乱了人们通常阅读文字的顺序。
问：为什么这么糟糕？
A：热门发布。
问：usenet和电子邮件中最烦人的事情是什么？
Missing semicolon.
--
A: Because it messes up the order in which people normally read text.
Q: Why is it such a bad thing?
A: Top-posting.
Q: What is the most annoying thing on usenet and in e-mail?
缺少包括警卫。
Missing include guards.

[...]
缺少分号。

Missing semicolon.
现在，它看起来像是：
MyClass.h
---- -----------
#ifndef __MyClass_h__
#define __MyClass_h__
class MyClass {};
#endif
Foo.h
--------
#include" MyClass.h"
class Foo {
MyClass * bar;
};
然而，问题仍然存在。
Now, it looks like that:
MyClass.h
---------------
#ifndef __MyClass_h__
#define __MyClass_h__
class MyClass {};
#endif
Foo.h
--------
#include "MyClass.h"
class Foo {
MyClass* bar;
} ;
However, the problem remains.

当然，问题是与你的内容无关
体验...从你显示的两个文件看来一切正常，是不是可能这个问题与其他标题有关？

Of course, the problems were not related with what you are
experiencing... from the two files you shown everything seems ok, is it
possible that the problem is related to some other header?
