vscode配置c++项目 include路径等

装c++环境

gcc和g++都要
以ubuntu为例

sudo apt-get instal gcc
sudo apt-get instal g++ #没装会报错找不到比如iostream头文件

装c/c++、c++ IntelliSense插件

version1.70开始c++ IntelliSense没了，合并到c/c++了

include path

关键是 配置c++ IntelliSense插件：这个插件会帮你解决所有include path的问题
ctrl+shift+P打开Command Palette,运行C/C++: Edit configurations... 生成c_cpp_properties.json

debug

配置

F5会生成launch.json，然后配置这个文件
有些时候不会，则在项目顶层目录的.vscode目录下新建launch.json，
打开此文件在编辑界面右下角会出现add configuration...按钮，点击然后选择c/c++(gdb): Launch，然后填写launch.json内容即可
program指明调试的可执行文件路径，args指定传递给可执行文件program的参数，比如：

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.

启动调试

如何调试：自己编译，然后F5唤起调试
