＃包括 <Header.h> #include“ Header.h”正在编译时未编译

Question

不明白为什么#include <Header.h> #include "Header.h"与Visual Studio 2008一起编译时#include <Header.h>没有编译。我缺少什么吗？

Answer 1

The two forms of #include search for headers differently.

You can find which paths are searched for each form in the #include MSDN documentation.

Answer 2

They have different purposes.

The brackets < and > are for standard header files, while the quotes " are for your header files.

Here is another question with more information regarding this:

What is the difference between #include <filename> and #include "filename"?

Answer 3

when you mention header file <>, it looks in standard includes, but when header file is included with "", starts with current directory,then will look at standard includes. Here, in this case, Header.h is in current directory, may not be in standard includes.
