 C# CLASSES / OBJECTS
</h2>

A class is a template for objects, and an object is an instance of a class. Objects are entities inside a class. 
Example: <code>color</code> is an object of <code>class car</code>. 


<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>class Car 
{
 string color = "red";
}
</code></pre>
<div class="highlight__panel js-actions-panel">
<div class="highlight__panel-action js-fullscreen-code-action">

 C# FIELDS (variables)
</h2>

A variable declared directly in a class is often referred to as a field (or attribute). 
Example 


<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>int myNum = 5; // Integer (whole number)
double myDoubleNum = 5.99D; // Floating point number
char myLetter = 'D'; // Character
bool myBool = true; // Boolean
string myText = "Hello"; // String

 C# ACCESS MODIFIERS
</h2>

Access modifiers are keywords which are used to set the access level/visibility for classes, fields, methods and properties. 
Examples 
<code>public</code>, <code>private</code> &amp; <code>protected</code>: Are what you would probably only use, unless you reach god level status 😂.

<code>internal</code>: Are for gods.

 <a name="c-properties" href="#c-properties">

 C# PROPERTIES
</h2>

Properties are just fields (variables) with access modifiers, the moment you put "public, etc." on a field (variable) it becomes a property. 
Example 


<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>class Car
{
 public string model; // public
 private string year; // private
 string type; // private

 // The `{set; get;}` means you can access and change the property.
 public string model {set; get;} // public
}
</code></pre>

 C# CONSTRUCTORS
</h2>

A constructor is a special method that is used to initialize objects. 

<blockquote>
💡 A constructor is a method that gets called or runs when a class is created. 
It can be used to set initial values for fields. 
The constructor name must match the class name. 
It cannot have a return type (like void or int).

All classes have constructors by default: if you do not create a class constructor yourself, C# creates one for you. However, then you are not able to set initial values for fields. 

</blockquote>

<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>// Create a Car class
class Car
{
 public string model; // Create a field

 // Create a class constructor for the Car class
 public Car()
 {
 model = "Mustang"; // Set the initial value for model
 }

 static void Main(string[] args)
 {
 Car Ford = new Car(); // Create an object of the Car Class (this will call the constructor)
 Console.WriteLine(Ford.model); // Print the value of model
 }
}

// Outputs "Mustang"

## C# CLASSES / OBJECTS
A class is a template for objects, and an object is an instance of a class. Objects are entities inside a class.
**Example:** `color` is an object of `class car`.
```c#
class Car 
{
  string color = "red";
}
```

## C# FIELDS (variables)
A variable declared directly in a class is often referred to as a field (or attribute).
**Example**
```C#
int myNum = 5;               // Integer (whole number)
double myDoubleNum = 5.99D;  // Floating point number
char myLetter = 'D';         // Character
bool myBool = true;          // Boolean
string myText = "Hello";     // String
```

## C# ACCESS MODIFIERS
Access modifiers are keywords which are used to set the access level/visibility for classes, fields, methods and properties.
**Examples**
`public`, `private` & `protected`: Are what you would probably only use, unless you reach god level status 😂.

`internal`: Are for gods.

## C# PROPERTIES
Properties are just fields (variables) with access modifiers, the moment you put "public, etc." on a field (variable) it becomes a property.
**Example**
```c#
class Car
{
  public string model;  // public
  private string year;   // private
  string type; // private
  
  // The `{set; get;}` means you can access and change the property.
  public string model {set; get;} // public
}
```

    Car Ford = new Car();  // Create an object of the Car Class (this will call the constructor)
    Console.WriteLine(Ford.model);  // Print the value of model
  }

// Outputs "Mustang"
```

    Car Ford = new Car("Mustang", "Red", 1969);
    Console.WriteLine(Ford.color + " " + Ford.year + " " + Ford.model);
  }
