Week 1 Presentation Guides

This week's presentations will focus on core language constructs in C#. You will be going over some aspect of C# as a language and how it represents common programming paradigms and constructs.

Terminology

Programming languages often have their own terminology for referring to common constructs. As just one example, C# refers to what might otherwise be called a "function" as a method.

For your presentation, please cover:

  • C# terminology - what is meant by method, assembly, the CLR, managed code, and unsafe code in the specific context of the C# language.
  • What other terms might refer to these constructs in other programming languages? (No need to focus on any one language, examples from multiple other languages are OK.)
  • Feel free to include any additional unique terminology that stands out to you or that you feel is important.

Core Syntax

C#'s syntax follows some basic rules which are very similar to those followed by other languages commonly referred to as "C-style" languages. While it follows these rules largely, it does have its own unique intricacies.

For your presentation, please cover:

  • The core aspects of C# syntax, such as: how to terminate a statement, how to continue something onto a new line, how to start and end a block of code (e.g. for an if statement), how to write an if statement and a for loop, and so on.
  • How to print output to the console and how to read user input from the console (hint: Console object)
  • Inline vs. traditional syntax (i.e. using a class and Main() method versus simply typing code in a .cs file at the high level).
    • I prefer to use the traditional syntax - of defining a class and a Main() method - because it makes your code more explicit. I strongly recommend using this approach.

Object-Oriented Programming

You have probably encountered object-oriented programming in previous courses or programming experience, and we will be covering it in much more depth during Week 3 when we discuss polymorphism. Thus, your presentation need not go into an extreme level of detail. Consider this a review of the subject for those with experience but who just need a quick refresher before diving into more advanced topics.

For your presentation, please cover:

  • What is object-oriented programming?
  • What are some of the main features and advantages of OOP?
  • How does C# implement OOP (keep it basic - we will be covering polymorphism, abstraction and so on later.)
  • A brief comparison to another language of your choice, and at least one way that C#'s OOP model differs

Value Data Types

C# is a strongly-typed language. This means that all variables must be given a data type when defined, and that variable may only ever contain data of that type for its entire lifetime. While you will use a very wide variety of types in C#, there are a few important data types that are central to the language and could be seen as its "base" types.

For your presentation, please cover:

  • The core numeric value data types (e.g. int, uint...) and bool and char.
    • Don't worry about struct/enum/etc types - we will be covering those later.
  • A very brief, high-level description of value versus reference types
  • The concept of a strongly-typed language (which C# is) versus a dynamic-typed language (such as Python or JavaScript).
  • You may also discuss other non-numeric non-value data types like object and string if you need more content to fill out your presentation.
