我去编译我的程序的最新版本，令我惊恐的是VS给了我以下构建错误消息。当我单击错误消息让它解决问题时，它将我带到ctype.h头文件？
1>c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\ctype.h(22): error C2143: syntax error : missing ';' before 'string'
1>c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\ctype.h(22): error C2059: syntax error : 'string'
1>c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\ctype.h(22): error C2143: syntax error : missing ';' before '{'
1>c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\ctype.h(22): error C2447: '{' : missing function header (old-style formal list?)
现在我知道我还没玩过ctype.h。
自上次构建以来我编辑的唯一文件甚至还没有进入主代码的入口点。
我会把它们包括在下面。

是否有其他人知道这是什么类型的错误以及为什么会发生错误？
答案 0 :(得分：7)
你在BowlingPin课程结束时遗漏了一个分号： - ）
当编译器扩展BowlingPin.h的#include时，在它之后编译的下一段代码将触发'预期的分号'错误;在这种情况下，它碰巧出现在ctype.h中（必须通过iostream包含 - 注意Entity.h不会触发错误，即使它在iostream之前包含，因为Entity.h已经包含在BowlingPin.h，由于pragma once），它只编译了一次。
