ROS cannot automatically complete when writing code

• First change the cpp dependency

Enter the c_cpp_properties.json file and change "cppStandard" on line 16 to "c++17"

• Then add the local ROS library to the search path

Add "/opt/ros/kinetic/include/**" to line 8 "includePath", note that here you need to change kinetic to your own ros version

• The entire c_cpp_properties.json file code is placed here (everyone remember to change kinetic to your own ros version)

{
  "configurations": [
    {
      "browse": {
        "databaseFilename": "${default}",
        "limitSymbolsToIncludedHeaders": false
      },
      "includePath": [
        "/opt/ros/kinetic/include/**",
        "/usr/include/**"
      ],
      "name": "ROS",
      "intelliSenseMode": "gcc-x64",
      "compilerPath": "/usr/bin/gcc",
      "cStandard": "gnu11",
      "cppStandard": "c++17"
    }
  ],
  "version": 4
}

 After the change is made, it will be automatically completed when writing the code
