bash: pacman: command not found

Wanted to add C/C++ Clang Command Adapter extension but it requires prior clang installation into my VScode. Tried to install clang using this youtube tutorial: https://www.youtube.com/watch?v=TLh--v8OxHE

Everything was going smoothly but at 12:35 when i type: "$ pacman -Ss clang"

Instead of displaying available clang installation packages, it shows the error: bash: pacman: command not found

Please suggest an alternate command to "pacman" or even a way to install clang into my VScode.

Tried to other bashes from the internet but apparently none of them contain the command "pacman" anymore.

  #setting.json
{
   "terminal.integrated.shell.windows": "C:\\Program Files\\Git\\bin\\bash.exe","terminal.integrated.shellArgs.windows": ["-i"]

}

Expected: //clang installation packages. Actual: bash: pacman: command not found
