C++頭包含

Question

雖然我有一類我在執行類似的頭文件：

#include<Utility.h> 

我仍然得到致命錯誤：Utility.h：沒有這樣的文件或目錄

有什麼想法爲什麼？ Utility.h和Utility.cpp在我當前的項目文件夾中

Answer 1

#include "Utility.h" 

這是包含您編寫並存在於您的項目中的.h文件的方式。

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>.
