ubuntu 配置vscode和C++环境

1、下载vscode
下载链接：https://vscode.download.prss.microsoft.com/dbazure/download/stable/e8653663e8840adaf45af01eab5c627a5af81807/code_1.95.2-1730981514_amd64.deb

2.安装vscode
cd /home/developer/Downloads/
sudo apt install code_1.95.2-1730981514_amd64.deb

3、安装中文显示插件
依次打开：file-preference-extension
搜索：chinese
安装，按提示重启VScode即可

4.配置c++编译环境

(1)sudo apt install g++ gdb

(2)安装vscode的C/C++插件

依次打开：file-preference-extension
搜索：C++
安装扩展 c/c++,c/c++ extenstion pack c/c++ themes

(3)配置文件修改

在代码目录下新建.vscode文件夹，在其下新建三个文件：

lauch.json

5.调试运行第一个C++程序

（1）新建first.cpp

#include<iostream>

int main(){
    std::cout << "hello world"<<std::endl;
    return 0;
}

（2）运行

依次点击 运行—启动调式，在终端中看到 hello world 即为成功
