200Part III: Introduction to ClassesA Ray of Hope: A List of ContainersLinked to the C++ LibraryI believe everyone should walk before they run, should figure out how to performarithmetic in their head before using a calculator, and should write alinked list program before using a list class written by someone else. Thatbeing said, in Chapter 27, I describe other list classes provided by the C++environment. These classes are known more generically as container classesbecause they contain other objects — array and linked list are just two examplesof container classes.
