Gain insights into fundamental and advanced C# programming concepts. Learn about conditional statements, loops, methods, arrays, classes, inheritance, interfaces, and delegates through practical challenges.

This course introduces you to fundamental programming concepts in C#, one of the most popular languages in the world. The highly interactive course begins with a simple Hello world program and proceeds on to cover common concepts such as conditional statements, loop statements, and methods in C#. It also reflects upon the idea of arrays as well as the power they give to the programmer to write better code. Finally, it dives deeper in order to teach about advanced concepts such as classes, inheritance, interfaces, and delegates in C# through interactive challenges and exercises.

C# for Programmers: A Practical Guide

# Polymorphism Definition 
The term **Polymorphism** means the ability to take many forms. It occurs if there is a hierarchy of *classes* which are all related to each other by *inheritance*.

# Subtyping

**Subtyping** is a form of *polymorphism* in which another *class* *inherits* from a **base** *class* to *generalize* a similar behavior. 

You basically have a *method* *inherited* from **base** *class* but it is implemented differently in the **child** *classes*.

## Example

Let's take a look at an example of *polymorphism* below.
