c++ - C++ 头文件包含

Question

尽管我在实现中包含了一个类的头文件，例如：

#include<Utility.h>

我仍然收到致命错误：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 <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>. 

Answer 2

#include "Utility.h"

这是包含您编写并位于项目中的 .h 文件的方法。
