手動添加bits/stdc++.h到vs2017的步驟是怎樣的

這篇文章給大家介紹手動添加bits/stdc++.h到vs2017的步驟是怎樣的，內(nèi)容非常詳細(xì)，感興趣的小伙伴們可以參考借鑒，希望對大家能有所幫助。

本機(jī)環(huán)境：win10系統(tǒng) 64位 vs2017

最近碼代碼時偶然發(fā)現(xiàn)了bits/stdc++.h這個頭文件（萬能頭文件），基本上所有的代碼只要用了這個頭文件就不再寫其他頭文件了。

看到它就仿佛開啟了新世界（也有缺點(diǎn)，就是導(dǎo)致編譯速度變慢，不過一般可以忽略不計(jì)）。

【如果安裝了MinGW的直接在文件夾里面找到bits這個文件夾，把里面內(nèi)容復(fù)制粘貼到vs的頭文件庫里面】

1 .新建txt文檔，把以下代碼（stdc++.h源碼）復(fù)制進(jìn)去：

2. 把txt文檔改名stdc++.h

3. 打開vs2017的安裝目錄

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\include格式類似上面

在“include”目錄下新建文件夾“bits”，然后把剛才的bits/stdc++.h移入。

4. 大功告成
