C ++标头包含

Question

虽然我在我的实现中包含了类的头文件，如：

#include<Utility.h>

我仍然会遇到致命错误：Utility.h：没有这样的文件或目录

有什么想法吗？我当前项目文件夹中的Utility.h和Utility.cpp

Answer 1

#include "Utility.h"

这是包含您编写的并且在项目中的.h文件的方法。

Answer 2

#include <file>
This variant is used for system header files. It searches for a file named file in a standard list of system directories. 

#include "file"
This variant is used for header files of your own program. It searches for a file named file first in the directory containing the current file, then in the quote directories and then the same directories used for <file>.
