Key Concepts

Test Program (User Input and Reverse Order Processing)

A test program is a small application used to validate the functionality of the implemented class. In this context, the program will prompt the user for inputs, push the entered strings onto the stack, and then pop them out to display the strings in reverse order. This demonstrates both the proper functioning of the stack operations and the overall user interaction within the application.

Composition vs Inheritance

Composition and inheritance are two fundamental design techniques in object-oriented programming. Composition involves building classes by combining objects of other classes, while inheritance creates a new class based on an existing class. The comparison is important here since the initial implementation of Stack used composition, and the task requires reimplementing it using inheritance, thereby demonstrating the differences and use cases of the two approaches.

UML Diagrams

Unified Modeling Language (UML) diagrams provide a standardized way to visualize the design of a system. In object-oriented design, class diagrams are used to represent classes, attributes, methods, and the relationships between them. Here, the UML diagram would illustrate the inheritance relationship between the Stack class and its superclass list, along with the operations and data structure to be implemented.

Stack Data Structure

A stack is an abstract data type that follows the Last-In-First-Out (LIFO) principle. It supports operations such as push (to add an element), pop (to remove the most recently added element), and sometimes additional operations like peek (to view the top element). It is commonly used in scenarios where reverse order processing is required, such as undo mechanisms and expression evaluation.

Inheritance

Inheritance is an object-oriented programming concept where a class (subclass) derives properties and behaviors from another class (superclass). It promotes code reusability and establishes a relationship between a base class and its derived classes, which can extend or override functionalities. In this context, a new Stack class is created by inheriting from a list, enabling it to utilize and extend the functionalities of a standard list implementation.
