// List.h (Header specifications for Lab 4's implementation of a stack class) // This is a group project. You must implement all files in this specification // for full credit. Do not create class functions not listed in this specification. // For example, you should modify Lab 3 functions such as insertFirst to be used as // push, used in a typical stack implementation. Others may be modified as necessary // Optionally, implementation files not mentioned in this header may be eliminated. #ifndef H_List #define H_List #include <iostream> #include <cassert> // definition of the linked list node used template <class Type> struct nodeType { Type info; nodeType<Type> *link; }; // class definition starts here template <class Type> class List { public: List(); // default constructor List(const List<Type>& otherList); // copy constructor ~List(); // destructor const List<Type>& operator= (const List<Type> &); // overload assignment operator. void initializeList(); // list cleared to an empty state. bool isEmptyList() const; // determines if list is empty. int length() const; // returns number of records in list.
