Entry Types, Generics For generality, we use Stack entry for the type of entries in a stack a client can specify this type with a definition such as typedef int Stack entry or typedef char Stack entry i The ability to use the same underlying data structure and operations for different entry types is called generics typedef provides simple generics. Starting in Chapter 6, we shall use C++ templates for greater generality.Entry Types, Generics For generality, we use Stack entry for the type of entries in a Stack.
