• Indexers can be viewed as a smart array,
• Indexers are similar to properties except that their accessors take parameters.
• This "this" stands as suffix to the class
  • public type this [int index] // Indexer declaration
  • public int this [int index] // Indexer declaration Integer parameter
  • public string this [string index] // Indexer declaration string parameter

Pointier moves to

All the objects are initialized : Not Set and Get in "mystring" property

At the end of completing first feed , cursor returns to the point of origin.

Next the objects were passed to a method, to display the values.

Command line, displays the output.
