I am unable to install g++ package for running c++ programs.When i try to install this i get the following mesage

fslab@ubuntu:~$ sudo apt-get install g++
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package g++ is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package g++ has no installation candidate

Not sure what's causing that error, but try "sudo apt-get install build-essential". This will get you everything you need to be able to compile C or C++ programs. After that, "g++" should work.
