1. Order of Program

   • NameSpace
     • A Collection of related classes
     • Class
       • Class: is a construct a blueprint of real world objects that allows you to group, model and define the methods and variables and the behavior types of the objects and elements within the class. 
       • Class: Field, Constructor, Properties, Method
         • The order of a class should be: Field : private (data type); Constructor: 
         • Field: Public, Private or Static
           • Static Variable stays inside the class .  Instance Variable: is either Public or Private access modifier and can be used inside another "derived" class. 
         • Constructor
           • Constructor is a special method in the class that is called when an object is created. It initializes class members when an instance of the class is created. In Class = public nameOfClass()* to call in main - nameOfClass obj = new nameOfClass()* *Depending on how its used the parameters can be included in the constructor  
         • Properties
           • -Properties Protect the class -Fields with the {get; set;} accessors - prevents corruption or misuse of code -properties can have either get or set or both accessors
         • Methods
           • A method is a code block that contains a series of statements. A program causes the statements to be executed by calling the method and specifying any required method arguments. In C#, every executed instruction is performed in the context of a method. A VERB
         • Abstract Class
           • Abstract : marks the parent class and prevents objects or instances of the class from being made in other classes. 
       • Method
         • statement
       • Object
         • Object is  an instance of a class, and they can be stored in either a named variable or in an array or collection
