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

# Definition

As in other *object-oriented programming* languages, the functionality of a **C#** program is implemented in *one* or *more* **classes**. 

The *methods* and *properties* of a **class** contain the code that defines how the *class* behaves.

Several types of **C#** *classes* can be defined, including **instance classes** (*standard classes* that can be instantiated), **static classes**, and **structures**.

# Declaring a Class

Skeleton of *declaring* **class** is:

//whatever is written inside [] is optional while declaring a class
//whatever is written inside <> is required while declaring a class

[private/public/protected/internal] class <Desired Class Name> [:[Inherited class][,][[Interface Name 1],[Interface Name 2],...]
{
 //Your code
}

* Classes are defined using the **keyword** `class` 

* The *access modifiers* like `private` and `public` are optional and don't necessarily need to be specified

* The keyword `class` is followed by an **identifier** to *name* the class. 

* *Instances* of the `class` can then be created with the `new` keyword followed by the **name** of the `class`.

Don't worry if you can't understand the whole syntax, you'll get familiar with it soon.

# Example
As an example consider the following *class*:
