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

# Features of C#
Although C# is derived from the [C programming language](https://en.wikipedia.org/wiki/C_(programming_language)), it has features such as [garbage collection](https://en.wikipedia.org/wiki/Garbage_collection_(computer_science)) that allow beginners to become proficient in C# more quickly than in [C](https://en.wikibooks.org/wiki/C_Programming) or [C++](https://en.wikibooks.org/wiki/Subject:C%2B%2B_programming_language). Similar to [Java](https://en.wikipedia.org/wiki/Java_(programming_language)) it is: 
* [object-oriented](https://en.wikipedia.org/wiki/Object-oriented_programming) 
* Comes with an extensive class library 
* Supports exception handling
* Multiple types of [polymorphism](https://en.wikipedia.org/wiki/Polymorphism_(computer_science)) 
* Separation of interfaces from implementations

# Uses of C#
Above mentioned features, combined with its powerful development tools, multi-platform support, and generics, make **C#** a good choice for many types of software development projects such as: 
* [Rapid application development](https://en.wikipedia.org/wiki/Rapid_application_development) projects 
* Projects implemented by individuals or large or small teams
* Internet applications 
* Projects with strict reliability requirements 
* Testing frameworks such as [NUnit](https://en.wikipedia.org/wiki/NUnit) make C# amenable to test-driven development and thus a good language for use with [Extreme Programming](https://en.wikipedia.org/wiki/Extreme_programming) (XP). 

Its [strong typing](https://en.wikipedia.org/wiki/Strong_and_weak_typing) helps to prevent many programming errors that are common in weakly typed languages. Because of these similarities to other languages, it is possible to introduce **C#** as a language with features of **C++** in addition to having the programming style of **Java**.

A large part of the power of **C#** (as with other **.NET** languages), comes with the common **.NET Framework API**, which provides a large set of classes, including ones for encryption, **TCP/IP** *socket* programming, and graphics. Developers can thus write part of an application in **C#** and another part in another **.NET** language (e.g Visual Basic .NET), keeping the tools, library, and object-oriented development model while only having to learn the new language syntax.

Because of the similarities between **C#** and the **C** family of languages, as well as **Java**, a developer with a background in object-oriented languages like **C++** may find **C#** structure and syntax intuitive.
