Windows下vscode配置c++20教程
Windows下vscode配置c++20
1.配置电脑上的C++环境
打开MSYS2的官网下载MSYS2
建议将安装在C盘，安装完后的路径应该为C:\msys64
安装完成后进入 https://packages.msys2.org/base/mingw-w64-gcc 选择适合自己电脑版本的gcc包
一般来说都是第一个
单击进入后选择安装命令
最后将下载好的MSYS2打开，输入以下命令
分别是安装gcc，make，gdb的命令
pacman -S mingw-w64-x86_64-gcc --disable-download-timeout
pacman -S mingw-w64-x86_64-make --disable-download-timeout
pacman -S mingw-w64-x86_64-gdb --disable-download-timeout
安装完以后应该可以在电脑路径C:\msys64\mingw64下找到gcc的配置文件。
最后就是配置环境，使用win + Q搜索高级系统设置，单击环境变量
找到系统变量中的Path双击进入
新建，将C:\msys64\mingw64\bin添加进去即可，注意最后一步步确定退出回来。
然后使用win + R并输入cmd,打开命令提示符，输入gcc -v检查是否配置成功，如果像我下面一样代表配置成功了
2.安装vscode
官网下载或微软商店下载都可以。随便安装到哪个盘，注意这一步的时候建议都选上。
然后打开vscode，Ctrl + Shift + X打开扩展页面
安装以下插件
安装完后就是配置.vscode文件文件夹中的四个文件了，如果没有的话就自己创建(c_cpp_properties.json，launch.json，settings.json，tasks.json)
c_cpp_properties.json文件

注意如果你是跟我前面说的一样将配置安装在C盘那么直接复制即可，不然需要更改一下上面代码汇总标注位置的路径
到此就配置完成了，可以创建文件进行写代码了。
代码编写完成后按F5进行编译运行，如果失败则看一下左上角带红框位置是否为g++.exe。成功编译后如下图所示，左边会生成一个exe文件。
最后可以按照我的代码运行一下检查一下你的版本是否为20。
最后提醒一下：如果想要使用F5执行文件的则文件路径中不能带有中文，否则会失败。
安利几款好用的插件：
-
Competitive Programming Helper (cph)
在这里可以方便的输入测试样例进行测试，注意版本！！！可以在设置里搜索cph将其改为20版本
-
background
可以更换背景图片，将背景图片换成自己喜欢的，当然右下角可能会爆出警告（直接无视即可）。
