#include<bits/stdc++.h>介紹：

最近寫編程題時發現了一個神奇的頭文件，#include<bits/stdc++.h>，很多人在只要引用了這個頭文件之后，就無須再引用其他頭文件，百度之后感覺挺有用的，寫題時方便快捷（不建議經常使用，如果長期使用容易把庫函數名字淡忘掉）

---

使用：

使用前 #include <iostream> #include <cstdio> #include <fstream> #include <algorithm> #include <cmath> #include <deque> #include <vector> #include <queue> #include <string> #include <cstring> #include <map> #include <stack> #include <set> using namespace std;int main(){return 0; } 使用后 #include<bits/stdc++.h> using namespace std; int main(){return 0; }

如何調用：

DEV C++軟件可直接使用 #include <bits/stdc++.h>

VS不行，需先在VS中添加此頭文件，方法如下

1.在安裝路徑下，依次進入:

VC --> Tools --> MSVC --> 14.13.26128(此文件夾名每個人會有不同) --> include

大致是這么個方向，但是要以實際情況為準

D:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.13.26128\include\bits
這是別人的

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include
這是我的路徑

如果實在找不到，建議下一個Everything，全局搜索include，然后進行一個個比對看看哪個目錄中含有自己用的頭文件（如最常見的stdio.h），就是這個啦

2.在 include 文件夾下新建一個 bits 文件夾，在此文件夾下添加 stdc++.h 頭文件，內容就是以下代碼塊中的代碼

3. 之后VS 就可以直接添加頭文件 #include <bits/stdc++.h> 使用了。
