How to update the Clang compiler from version 3.1 to version 3.4 in Debian Linux?

Question

It is as what the question is saying, I am new on Linux. I need the Clang++ compiler update to version 3.4 for the assignment that I need to do. I simply just typed in Terminal

sudo apt-get install clang++

this command only install/update my clang++ to version 3.1. And I have no idea how to update it. I went on the clang++ debian website and see different packages but have no idea how to update it. I copied some command but they don't run on Terminal. This is the clang++ site I went to. I tried search online for tutorial or help but there was none that could help me with this issue. I am new to Linux so I will really appreciate it if someone give out a detailed update process. Thank you for your time.

My first try would be to remove any clang components that are already installed if I'm sure that I don't need them and only an updated version will do.

Next I would try following the instructions from the link you provided. I can see how it could be confusing if you haven't done it before.

To install all the v3.4 packages on your Debian Wheezy system, I would become root with su - and execute the commands below, or use sudo in front of every command.

cat - >> /etc/apt/sources.list << HERE
deb http://llvm.org/apt/wheezy/ llvm-toolchain-wheezy main
deb-src http://llvm.org/apt/wheezy/ llvm-toolchain-wheezy main
