While running the Linux vm on a Chromebook, what do I have to do to compile and run a C++ program?

Question

So I was creating my first (noob-ish) C++ program, but when I tried to compile it gave me this.

-bash: g++: command not found
-----@penguin:~$

And I don't know how to install or fix it.

Answer 1

I don't have a chromebook, so I cannot verify:

sudo apt update
sudo apt upgrade

sudo apt install build-essential
sudo apt install software-properties-common
 
sudo apt install gcc g++
