2) Can be accessed directlu
Reference Types

Block Level: Variables declared within an If...Then, For...Next, Do...Loop Block
Procedure-Level: Variables declared within the procedures.
Module Level: Variables declared outside a procedure.
NameSpace-Level: Variables declared outside of a procedure, but given public accessibility(PUblic or Friends)

Public
1.Declared with Public keyword
2.Accessible from anywhere in the same module.
Friends
1.Declared with the Friend keyword.

Protected
1.Declared with the Protected keyword.
2.Accesible only within the class in which they're declared or a class that inherits from that class.
Private
1.Declared with the Pirvate keyword.
2.Assesible from the Module, class, or structures in which they're declared.
3,Private keyword canot be used within the procedure.
Q. Differentiate Option Explicit with Option Stric.

Function Procedures: Just like sub procedure, but they can return a value.

A.
ByVal: A copy of the value is passed to the procedure.
ByRef: A reference to the location of the value is passed to the procedure, which allows the procedure to modify the original value.
Q. In VB, While we are using ByVal and ByRef, which is the defail one?
A. ByRef.
Q. In VB.NET, while we are using ByVal and ByRef, which is the default one?
A. ByVal.
Q. How can you make the parameters of your procedure Optional?
