Scope:

• The portion of program that refers to the declared entity by its name is referred as scope.
• It refers to the lifetime and accessibility of a variable. If the variable is declared outside the class it is accessible to all the class methods.

• If the variable is declared within a method, then its scope is visible only inside the method and these variables cannot be accessed outside the method.
