Two problems that may be encountered when vscode configures c++ (header files cannot be found and compiled files cannot be found)

1. The header file cannot be found. There
is no need to change much . The header file can not be
found because you did not modify the includepath in c_cpp_properties.json to the location of the header files and libraries of the mingw or other compilers you installed.

2. Most compilation failures are gcc , Gdb, g++ did not add environment variables (or did not modify the place with text annotations in the tasks.json and launch.json files):
tasks.json
code:

"tasks": [        {
    
                
"type": "cppbuild",   
"label": "C/C++: g++.exe build active file",            "command": "C:\\msys64\\mingw32\\bin\\g++.exe",
/*这里是g++的位置，编译器的gcc、gdb、
g++都需要加入环境变量pash中，
大多问题都是这三个没有加入环境变量, */
    "args": [  
    "-g",               
    "${file}",   
    "-o",
    "${fileDirname}\\${fileBasenameNoExtension}.exe" 
                      
    ],
              
"options": {
    
      
 "cwd": "${workspaceFolder}" 
 },          
"problemMatcher": [                
"$gcc"          
  ],          
"group": {

  },

    }    ],

  ],            
"preLaunchTask": "C/C++: g++.exe build active file"        }    ]}

I encountered these two problems. If you have other problems, please leave a message.
I am happy to help (in fact, I will only do this) but I am willing to solve other problems that may be encountered
