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

## Structs VS Classes 

**Structs** are similar to *classes* but have subtle differences. 

They are used as lightweight versions of *classes* that can help reduce *memory management* efforts when working with small data structures. In most situations, however, using a standard class is a better choice.

>The principal difference between **structs** and **classes** is that *instances* of **structs** are values whereas *instances* of **classes** are *references*. 

Thus when you pass a **struct** to a *function* by **value** you get a *copy* of the *object*, so changes to it are not reflected in the original because there are now **two** distinct *objects* but if you pass an *instance* of a *class* by **reference** then there is only **one** *instance*.

##  Declaring a struct

**Structures**, or **structs**, are *defined* with 
* `struct` *keyword* 
* followed by an *identifier* to *name* the *structure*.
