何时使用#include<>和#include“ " [英] When to use #include <> and #include " "

问题描述

我的问题是，如果我创建了自己的库，它位于自己的

安装目录中，要引用它的头文件，最好使用


#include" MyLibrary.h"

或


#include< MyLibrary.h>


假设其他组将使用此库。我认为答案

应该使用<>符号，但我会感兴趣的原因。

定义为引用字符串的解释是什么（和

你使用的是哪一组分隔符）。

废话。查找标题的路径是不同的，

没有其他内容（详情请参阅一本好的C ++书籍）。

My question is, if I have created my own library which lives in its own
install directory, to refer to its header file is it better to use

#include "MyLibrary.h"

or

#include <MyLibrary.h>

Assume that this library will be used by other groups. I think the answer
should be use the "<>" notation but I would be interested why.

<> is reserved for the standard library and some system libraries. so you
may use ""

<> assures that if you give it the name of a standard header, you get
that for sure. Otherwise the behavior of #include is implementation
defined as to what the interpretation of the quoted string is (and
which set of delimeters you used).

Nonsense. The path in which the header is looked up is different,
nothing else (see a good C++ book for details).
