The static 'main' method of a C# application is generally known as:

Complete the swap method declaration so that the values of parameters x and y are swappedstatic void swap(...){ Int32 tmp = x; x = y; y = tmp;}

data types are data types that you define in your own code. data types are not built into the C# language, unlike primitive data types. You can use types in your code just as you use primitive data types, but only after you define the data type in your code.

is the act of designing classes that provide a full set of functionality to yourclass's data without exposing the data directly.

enables you to define one class in terms of another. Derived classes inherit from the base class.

enables you to treat a collection of classes derived from a single base class in a uniform way. You retrieve the derived classes as a base class, and C# automatically calls the correct method in the derived class.

In the class below, what is the term used for method 3:class Point{ public int X; public int Y; public Point() //Method 1 { X = 0; Y = 0; } public Point(int InitialX, int InitialY) //Method 2 { X = InitialX; Y = InitialY; } ~Point() //Method 3 { X = 0; Y = 0; }}

Placing the modifier before a field definition indicates that all objects of the same class will be sharing the same value.

An object can perform work and notify the caller when something happens during the process. This 'something' is known as
