How to resolve compiler to compile c++ program?

Question

Whenever I try to compile a c++ program with g++ hello.cpp, I get:

The program 'g++' can be found in the following packages:
 * g++
 * pentium-builder
Try: sudo apt-get install <selected package>

Then if I run sudo apt-get install g++ it outputs:

E: Unable to correct problems, you have held broken packages.

To fix 'held broken packages' error:

sudo apt-get install -f

sudo apt-get clean
sudo apt-get update
