Answer 1

Try to set g++ to your system path.

Answer 2

I faced the same problem while running the code from command line. And found out that I messed up with MinGW installation. So I reinstalled it,

Do this while installing MinGW ----

1. After downloading, install MinGW and wait for the “MinGW Installation Manager” to show up.
2. When the “MinGW Installation Manager” shows up, click on mingw32-gcc-g++ then select “Mark for Installation”
3. In the menu at the top left corner, click on “Installation > Apply Changes”
4. Wait and allow to install completely. Ensure you have a stable internet connection during this process.

when it is done, then edit the environment 'Path' Variable as stated in other answer.

In short I followed this

For me, it's easily fixed by two steps, as below:

1. Set the environment variable:

   C:/MinGW/bin

2. Paste the following code in the "launch.json":

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "C++ Compiler",
            "type": "cppvsdbg",
            "request": "launch",
            "program": "C:/MinGW/bin",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true
        },
    ]
}

Answer 4

Open mingw-w64 folder click on mingw32->i686-w64-mingw32->bin copy this path and set this path in your system environment variables

Answer 5

If you keep getting this error, make sure you set up MinGW in Path variable, not separated user\system variables: pic link on imgur here

Answer 6

The best thing to do is first of all ensure you have download minGW properly you can refer from this site https://www.msys2.org/ , Be sure to follow all the steps inorder for it to install completely (ps:it takes a while),, after that you can go to environment system variables via settings and a new path C:\msys64\mingw64\bin or wherever your msys64 file might be stored. Hope this helps

Check if you have installed g++ by typing g++ --version. If you already have g++ compiler installed, just hit ctrl + S to save the changes you made, then run the code.
