There are two types of array. Fixed Size and Resizable.

Fixed Sized

Dim TheArray(9) As {Type}


You see the number 9 (nine) this indicates the array has room to store 10 objects, not 9.


Accessing Array Items
Let take the example array, you can access the item directly through its Array Index.
The first item is TheArray(0)...

Recursive Methods are method that called themselves from with the body of their definition.

Lets do the classic Fibonacci

 Public Function Fib(ByVal x As Integer) As Integer  If x < 1 Then Return 0  Return Fib(x - 1) + x End Function

To see how it works lets step through it manually.

Methods (Subroutines)

There are two basic types of method in VB.NET, the Subroutine and the Function.

Using Methods lets you break up code, into separate reusable sections (Methods) of code.

The difference between is this
A Function returns a value, whereas a Subroutine doesn't.

You have been using a Subroutines, without knowing.

Boolean Logic Operators
Not
Evaluates the opposite value. This called Negation.

A      Z
False  True
True   False

Dim A As Boolean = FalseIf Not A Then Console.WriteLine("A was False")End If

AND
When A and B are both True value is True, otherwise value is False.

A      B      Z
False  ...

Defining a Variable

Dim {Variable Name} As {Type}

What this saying is reserve me a piece of memory big enough to store an object of this type and name a reference to that location with the variable name.

Module Module1  Sub Main()    Console.WriteLine("Variables")    Dim A As Integer   End SubEnd Module
