注意：本实验vscode是安装在mac电脑上的

vscode连接步骤

安装ssh插件

vscode打开ubuntu目录

如果弹出窗口提示是否文件夹可信任，选可信任

vscode远程执行hello.cpp

vscode新建hello.cpp如下

终端远程到ubuntu机器，查看下g++的安装位置，查看命令：whereis

配vscode如下

然后会在.vscode隐藏文件夹下面生成一个tasks.json文件，如下

可以在tasks.json里修改label的名称，如改为: test，如下

这时候ubuntu机器对应目录下是生成了hello可执行文件，如下

会在vscode右下方显示：添加配置，如下

在.vscode隐藏文件夹下生成一个launch.json配置文件

这时候的launch.json文件内容如下

可以修改name; program名称，如下
