title: Are "n" or "ch" prefixes common prefixes when naming int or char variables in C++?
body: <p>I'm currently going through <strong><a href="http://www.learncpp.com/" rel="nofollow">learncpp.com</a></strong>'s C++ tutorials and I'm seeing that their variable naming trend has them naming int variables with an "n" prefix (i.e. int nValue) and "ch" prefixes for char variables (i.e. char chOperation).  Is this something that is commonplace in the industry that I should form as a habit now?</p>
