The document discusses interfaces and polymorphism in object-oriented programming. It describes how interfaces can be used to allow classes to be reused for different types of data by implementing common methods. It provides examples of implementing a Measurable interface to allow different classes like BankAccount and Coin to be used interchangeably with a DataSet class. The key points are that interfaces define required method signatures but not implementations, classes can implement multiple interfaces, and polymorphism allows the same method calls to behave differently based on the actual object type.

Summary
HW6: Account Management
In HW4, you kept track of multiple usernames and its associated password using arrays.
However, usernames and passwords are typically part of a “User” object which in turn may be
part of an “Account” object. Accounts also typically require a certain level of security beyond
the typical encryption mechanisms. This assignment goes deeper into the concept of OOP as you
create objects that requires proper rules and scope for correct usage.
Aside: As with Item objects from HW5, Account and User data is typically stored in databases.

o Everyproperty(instancevariables)canbesetandgetcorrectly(whereallowed) ? Every public
method can be called successfully (and return the correct result)
Class Design: User
The User class is intended to be an abstract and simplified representation of a user

? First Name (String)
? Last Name (String)
? Username (String)
? Password (String)
Class Invariant
? First and Last Name must not be empty
? Username must be at least four characters long

The document discusses various C++ programming concepts including:
- The cin statement is used to read input from the keyboard and store values in variables. It is often used with cout to display prompts.
- Variables must be declared with valid names using letters, digits, and underscores. Keywords like int and float cannot be used as names.
- Different data types like int, float, and char are used to store different kinds of data. Variables of the specified types need to be declared before use.
- Arithmetic operators like +, -, *, /, and % are used to perform calculations in expressions and assignments. Parentheses can be used to alter operator precedence.
The document discusses designing good object-oriented classes. It provides guidance on choosing appropriate classes, maintaining cohesion so that classes represent single concepts, minimizing dependencies between classes, and reducing side effects from method calls. Examples are given for common patterns when designing classes, such as keeping a running total, counting events, collecting object values, managing object properties, modeling object states, and describing an object's position. The reader is taught how to apply these design principles and patterns when modeling real-world problems as classes, methods, and objects.
What We Talk About When We Talk About Unit TestingKevlin Henney
Presented at ACCU (23rd April 2015)
These days unit testing is considered sexy for programmers. Who'd have thought it? But there is a lot more to effective programmer testing than the fashionable donning of a unit-testing framework: writing Good Unit Tests (GUTs) involves (a lot) more than knowledge of assertion syntax.
Testing represents a form of communication and, as such, it offers multiple levels and forms of feedback, not just basic defect detection. Effective unit testing requires an understanding of what forms of feedback and communication are offered by tests, and what styles encourage or discourage such qualities.
What styles of test partitioning are common, and yet scale poorly, are uncohesive and are ineffective at properly expressing the behaviour of a class or component? What styles, tricks and tips can be used to make tests more specification-like and scalable to large codebases? How do we choose between scenario-based and property-based test cases?

In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.
