title: how to change gcc compiler to c++11 on ubuntu
body: <p>I use ubuntu 12.04 and the default gcc is 4.6.3. It is not accepting c++11 commands and is giving me output saying the command is not c++98 compatible. I checked online and have seen people advising to not change default compilers on operating system as it becomes unstable. Can anybody suggest a fix or a safe way of downloading a gcc compiler that is c++11 compliant. </p>
