(BQ) Part 2 book "Fundamentals of computer programming with C#" has contents: Defining classes, text files, linear data structures, trees and graphs, data structures and algorithm complexity, lambda expressions and LINQ,.and other contents. | Chapter 14. Defining Classes In This Chapter In this chapter we will understand how to define custom classes and their elements. We will learn to declare fields, constructors and properties for the classes. We will revise what a method is and we will broaden our knowledge about access modifiers and methods. We will observe the characteristics of the constructors and we will set out how the program objects coexist in the dynamic memory and how their fields are initialized. Finally, we will explain what the static elements of a class are – fields (including constants), properties and methods and how to use them properly. In this chapter we will also introduce generic types (generics), enumerated types (enumerations) and nested classes. Custom Classes The aim of every program written by the programmer is to solve a given problem based on the implementation of a certain idea. In order to create a solution, first, we sketch a simplified actual model, which does not represent everything, but focuses on these facts, which are significant for the end result. Afterwards, based on the sketched model, we are looking for an answer (. to create an algorithm) for our problem and the solution we describe via given programming language. Nowadays, the most used programming languages are the object-oriented. And because the object-oriented programming (OOP) is close to the way humans think, using one easily allows us to describe models of the surrounding life. Certain reason for this behavior is, because OOP offers tools to draw the set of concepts, which outline classes of objects in every model. The term – class and the definition of custom classes, different from the .NET system framework’s, is built-in feature of the C# programming language. The purpose of this chapter is to get us know with it. Let’s Recall: What Does It Mean Class and Object? Class in the OOP is called a definition (specification) of a given type of objects from the real-world. The class represents a .
