Summary

The topics covered in this chapter are the basics of programming in the C# language. Using access modifiers, we can control access to different properties and methods in different modules of an application. While writing the code, a very common mistake that people make is to declare all the properties and methods as public. This is not the recommended way of programming in C#. We must logically evaluate the need for different access modifiers for each of the properties and methods present in a class.

Similarly, we should analyze the data types that we need to associate with each property used in the class. We must also analyze if we need a reference data type variable, or whether we are fine with a value type variable as they have a different implementation in the compiler memory and functionality. We should also utilize inheritance as it helps us to reuse code and structure...
