VSCode 配置C++环境并调成CLion风格

//2020.12.15更新发现了更更好用的自动补全插件(Tabnine)

后面的操作都是花里胡哨的。做完1、2、5就行了。

在这里插入图片描述直接安装Tabnine即可使用 //2020.03.20更新 ~~发现了更好用的自动补全插件(clang)。先装个LLVM (opens new window) 把LLVM/bin添加到环境变量安装vscode-clangd插件~~

1、商店中搜索C++，下载(如下图)

在这里插入图片描述

2、商店下载Code Runner插件

在这里插入图片描述 Code Runner插件通过终端编译运行代码，因此需要将g++所在的目录添加到环境变量中。不懂请搜索“mingw添加到环境变量”。一般DevCpp和Codeblocks的目录下有一个版本较老的mingw cmd下输入g++ -v检测是否添加成功

3、新建一个文件夹

在文件夹中创建c_cpp_properties.json，将以下代码写入

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "F:/Dev-Cpp/MinGW64/lib/gcc/x86_64-w64-mingw32/4.8.1/include"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "windowsSdkVersion": "10.0.17763.0",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "gcc-x64"
        }
    ],
    "version": 4
}

关键点是includePath的第二行：写入你自己的mingw对应的目录到这一步已经可以通过右上角的小箭头编译运行C++了但C++11的语法还不能用，因为编译选项在Code Runner的配置文件中

5、修改Code Runner配置文件

Ctrl + Shift + P打开settings.json 输入code-runner，会补全出一大串东西将cpp的那行修改，加上c++14的编译选项-std=c++14：

"cpp": "clear cd $dir && g++ $fileName -std=c++14 -o $fileNameWithoutExt && $dir$fileNameWithoutExt"

其中clear是为了在编译前清屏，看起来更清爽

6、创建stdc++.h文件

平时常用#include <bits/stdc++.h>，但现在并不能用(不知道为啥) 解决方法就是在MinGW64\lib\gcc\x86_64-w64-mingw32\4.8.1\include\c++\bits目录下创建stdc++.h文件将以下内容复制进去
