Basic Associative Array Functions

• Perl provides several built-in associative array management functions to help with deal with their special considerations

  %days = ( 'M', "Monday", 'T', "Tuesday" );

   

• The keys() function returns a list of keys: @letters = keys( %days );

Yields ( 'M', 'T' ) and places it in the array letters

• The values() function returns a list of values: @names = values( %days );

  Yields ( "Monday", "Tuesday" ) and places it in the array names

• The delete() function removes a Key-Value pair: delete( $days{'M'} );

   Yields ( 'T', "Tuesday" )
