Installing gcc newer version 4.6 in ubuntu

I am still a learner in installing packages in ubuntu. Actually, I had copied an iso image file of ubuntu from a torrent more than a year ago and I run with using Oracle Virtual Box on my Windows machine (primarily to compile in g++).

At that time I had installed gcc 4.4.1. Now I am updating it to 4.6 (gcc-4.6-20110610.tar.bz2). I don't know where my 4.4.1 package is stored, but the 4.6 package I am storing in a local folder. My questions are:

(1) Will my 4.4 package get affected with this new installation ?

(2) Is there a way that I can toggle between both compilations whenever I want (say gcc-4.4 or gcc-4.6) ?

If you install gcc 4.6 in a directory in your home folder (I guess that's what you mean by "local folder") then it will not affect your standard gcc 4.4 installation.

I have Ubuntu 11.04 and I have both gcc 4.5 (the standard version for Ubuntu 11.04) and gcc 4.4 installed. (I need 4.4 because NVIDIA's CUDA toolkit requires gcc 4.4). I installed them both via the package management system, not in a folder in my home directory. With this setup, gcc defaults to version 4.5, and if I want to use version 4.4 I have to type gcc-4.4.

As far as I know there is no official package for gcc 4.6 for Ubuntu yet.

the package4.4 won't be affected,and you could have both the two versions of gcc. But there is only one valid version's link toward the command 'g++' in default .
