    First, even though it’s probably obvious, you should mention that protected members use the keyword "protected."
     
    The main difference is when you derive another class ("third-generation" class) from the current derived class, private inheritance prevents the third-gen class from using the internal structure of the base class. With protected inheritance, you don’t have this problem (or feature, depending on how you look at it).
