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

## Introduction
From the [documentation](https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/passing-parameters) :

Passing by *reference* enables function 
* members
* methods
* properties 
* indexers 
* operators 
* constructors 

to change the value of the *parameters* and have that change persist in the calling environment. To pass a parameter by reference, use the `ref` keyword.

## Syntax
Here's the syntax used to pass a value by *reference*:
