beginner

beginner here, just stated learning C++ and i have come up against a small problem. Everytime i run or build one of my projects, the cmd window closes before i can see the results. Is there a way to stop the cmd window closing after it has run the code?
thanks for your time chaps.

or is it fairly easy to switch between languages once you've learnt one?
It generally takes a few before it gets ‘easy’ to switch, as languages tend to prescribe certain ways of doing things. For example, it's easier to switch between python and ruby, that it would be to switch between Java and Prolog.
