C ++语法错误和缺少类型说明符

Question

Visual C++ 2008 gives me this weird error, so I stripped out all of the excess stuff in my header file (util.h ), and it boils down to this:

#ifndef UTIL_H
#define UTIL_H

void pause();

#endif

When I try to compile the above code I get this:

Compiling...
util.cpp
util.h(4) : error C2144: syntax error : 'void' should be preceded by ';'
util.h(4) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
<snip>

I am deeply confused. Even if I comment out the ifndef, define, and endif, preprocessor directives, It still says the same thing.

Answer 1

After hours of looking, I finally figured it out!

The error is not in the header file itself. Header files are copied and pasted into source files, where they are included. So I looked where I included the file, and I saw in util.cpp:

#include "stdafx.h"b
#include "util.h"
<snip>

That extra 'b' is causing the error. C++ thinks it is a variable, but doesn't see a type specifier, so it assumes 'b' is a new integer. Then it thinks I should terminate its declaration with a ';' to precede 'void' . The entire issue is just a stupid extra character, and a not very helpful error message.
