How to write task.json to compile C++ file?

Question

Visual Studio Code

Hello.
Please tell me where I have an error
wrote a simple code on cpp

#include <iostream>
using namespace std;
int main() {
  //setlocale(LC_ALL, "");
int ans, x, y;
  bool f;
    std::cout << "hello!" << endl;
  cout <<" -------------------------" << endl;

return 0;
}

As stated in the VS Code documentation compiled a simple launch.json

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(Windows) Launch",
            "type": "cppvsdbg",
            "request": "launch",
            "program": "${workspaceFolder}/a.exe",
            "args": [],
            "stopAtEntry": false,
            "preLaunchTask": "mybuild",
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true
        }
    ]
}

and

task.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "mybuild",
            "type": "shell",
            "command": "g++",
            "args": [
                "${file}",
                "-g"
                  ],
            "group": "build",
            "presentation": {
                // Reveal the output only if unrecognized errors occur.
                "reveal": "always"
            },
            // Use the standard MS compiler pattern to detect errors, warnings and infos
            "problemMatcher": "$msCompile"
        }
    ]
}

Gives an error on startup

Invalid parameter format: /d

The MinGW64 compiler is installed, the path is registered in the PATH variable. Through the usual windows console, the file is compiled.
How to start compiling and debugging, where is the error?
Yes, I also read everything that google gave me, tried it, the error is the same.

Did you manage to find a solution? The situation is the same and I can't find anything similar.
