    What is the difference between private and protected in C++ classes?

    It seems that they do the same thing. i.e. protect outside functions from using whatever is private / protected.

    Protected will allow access from subclasses that publicly extend the class. Private won't.

    Think of it like this:

    A person's appearance is Public
    A person's internal workings (eg. heart, lungs) are Protected as they are common to all people and passed on.
    A person's memories/opinions/skills are Private and unique to that person.
