Hello all.

How I can install g++ compiler on kali linux 2.0?
I have run below commands before:

apt-get update
apt-get upgrade
apt-get install build-essential

i have not worked on 'kali' distro but i hope the process remains the same across distros when doing it from terminal:
1). sudo apt-get update
2). sudo apt-get upgrade
2). sudo apt-get install g++ (installs the most updated package)

then you can check the list of compiler packages with command:
dpkg --list | grep compiler

know the current g++ version used by the system:
g++ --version

these are very basic things. Any good online tutorial will explain these things(Google it), so follow any one .

hope this helps!

thank you so much
If apt is working and that is what you are going to use on Kali Linux (which I do not recommend to Linux beginners, as Kali Linux is a very advanced tool for security experts to try out!), then just execute the following command:
sudo apt-get install g++

However, since that command (the one you are using) is also possible (because Kali Linux is a Debian distro; like Ubuntu!), you should execute that as super-user! Currently you are not executing that as a superuser, whereas in Linux environment all of the install or uninstall and similar commands require to have superuser authentication. Either prepend sudo (command to execute the commands with super-user privileges), or use the root terminal (which would, at the beginning, ask for your password).
