关于VS2022不能使用<bits/stdc++.h>的解决方案(万能头文件)
来源:脚本之家    时间:2022-03-20 20:02:15

介绍

#include包含了目前 C++ 所包含的所有头文件,又称万能头文件,简直是开挂一般的存在。

你编程所需要的头文件基本上都囊括在了该万能头文件中,试想一下,将若干行头文件:

#include
#include
#include
#include
#include
......

只用一行代码#include来代替,是不是简单粗暴!

•如何在VS2022中使用万能头

可惜,这么好的万能头,在VS2022中不能使用,难道就此放弃吗?

不,作为21世纪有思想的时代青年,这点问题怎么能难道我呢?

首先,找到你本地VS的安装目录,在VS中找到 include 文件夹,我的在该路径上:

D:\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.31.31103\include

在 include 文件夹下创建一个bits 文件夹,并新建一个stdc++.h的文件,将如下代码复制到stdc++.h 文件中,即可在 VS2022 中使用万能头。

设置完成后,重启 VS 即可愉悦的使用万能头了,完结撒花!
