手動新增bits/stdc++.h到vs2017的詳細步驟

最近碼程式碼時偶然發現了bits/stdc++.h這個標頭檔案(萬能標頭檔案),基本上所有的程式碼只要用了這個標頭檔案就不再寫其他標頭檔案了。
看到它就彷彿開啟了新世界(也有缺點,就是導致編譯速度變慢,不過一般可以忽略不計)。
【如果安裝了MinGW的直接在資料夾裡面找到bits這個資料夾,把裡面內容複製貼上到vs的標頭檔案庫裡面】
1 .新建txt文件,把以下程式碼(stdc++.h原始碼)複製進去:

2. 把txt文件改名stdc++.h
3. 開啟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”目錄下新建資料夾“bits”,然後把剛才的bits/stdc++.h移入。
4. 大功告成
總結
以上所述是小編給大家介紹的手動新增bits/stdc++.h到vs2017的詳細步驟,希望對大家有所幫助!
