VScode on Ubuntu 18.04 LTS (cpp: error trying to exec 'cc1plus': execvp: No such file or directory)

In kernel of vscode

cpp: error trying to exec ‘cc1plus’: execvp: No such file or directory The terminal process "/bin/bash ‘-c’,
‘/home/viveksharmavs/anaconda3/bin/cpp -g
‘/home/viveksharmavs/Documents/c++ codes/viveksharma.cpp’ -o
‘/home/viveksharmavs/Documents/c++ codes/viveksharma”" failed to
launch (exit code: 1).

in launch.json

    {
        "name": "g++ - Build and debug active file",
        "type": "cppdbg",
        "request": "launch",

            {
                "description": "Enable pretty-printing for gdb",

                "ignoreFailures": true
            }
    {

How can I reset settings if needed, or how can I cure this problem? I want to do some C++ coding stuff, but I’m getting these errors.
