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

# What is a method?
 
**Functions** declared inside a *struct* or *class* are called *methods*. 

A *method* encapsulates a *block of code* that can be called from other parts of the program. 

The use of *methods* in **C#** increases **code reusability**. Literally, you can tag a particular section of code with a name (*method* name) and just call that name from anywhere of your program. 

>**Note:** In **C#** a *method* may or may not have a *return* type. 

# Declaring a Method

Every method has a unique signature consisting of:
* **accessor** (`public`, `private`, ...) 
* **optional modifier** (`abstract`) 
* a **name** 
* **method parameters** (if needed ) 

>**Note:** The **return** type is not part of the signature. 

A *method* prototype looks like the following:
