vscode配置

<bits/stdc++> 简介：#include <bits/stdc++> 就相当于引入了所有标准式函数库，即不用每次事先在cpp代码里输入:

#include <iostream>
#include <string>
#include <cstdio>
#include <cstdlib>
#include <cstring>
#include <vector>
#include <set>
#include <map>
#include <deque>
#include <stack>
#include <queue>
#include <algorithm>
...

mac上vs code中配置：

思路是在include目录中添加一个自己编写的”bits/stdc++.h”。

  1. 终端输入gcc -v -E -x c++ -找到红框中的地址

  2. 在访达中按组合键 shift+commond+G，在弹出的框中输入红框内容转到相应目录，创建一个bits文件夹

    /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include

  3. 新建stdc++.h文件复制如下代码，想添加什么常用头文件在endif前添加即可

c++ IntelliSense 插件 找不到include路径 解决方案：

将图一中红线部分填入c_cpp_properties.json文件中的includePath中即可。

注意： 路径最后添加 /**这表示递归添加这个路径下的所有的文件

添加
