Hi all
I am using Kubuntu 16.04
I write code in c++ and compile it using g++ .I think the version of c++ is c++ 11.
whatever be the reason i cannot use auto,unordered map and some other things in my pc.
I have googled quite a bit about updating to c++ 14 or some more advanced version which supports above things atleast.But in vain,I couldn't find any thing helpful that solves my problem.

Can someone help me how to run program in c++14 in my system??
And also I see some experienced coders compile program using something different rather than just
g++ prog.cpp Can someone elaborate on this ???

BTW Happy New Year to all of you
