Naming :: Acronyms and Abbreviations

How often do we have to look into the code when a class name or a variable name contains acronyms or abbreviations in it. For example consider the following class name:

class MyCPPProgram {};

The class name, MyCPPProgram, is correct and fine except that it can be more readable if we declared the class like this:

class MyCppProgram {};

I find the 2nd one more readable than the 1st one. We can also see a similar naming pattern in Java. For example the HttpServlet class. It's not HTTPServlet.
