I have both gcc 4.7.3 and 4.8.1 installed

But on running gcc --version I get

gcc (Ubuntu/Linaro 4.7.3-1ubuntu1) 4.7.3

I am an Ubuntu newbie and I don't know much about updating symbolic-links...

I searched the Internet, and found out about update-alternatives but was reluctant to use it...

Please can someone help me in choosing 4.8 over 4.7 & also tell me is it bad to have 2 versions of same gcc?
