Slicing Array Elements

Slicing Array Elements

You can also extract a "slice" from an array - that is, you can select more than one item from an array in order to produce another array.

#! /usr/bin/perl

@days = qw/Mon Tue Wed Thu Fri Sat Sun/;

@weekdays = @days[3,4,5];

print "@weekdays\n";

This will produce following result:

Thu Fri Sat

Note:-The specification for a slice must a list of valid indices, either positive or negative, each separated by a comma. For speed, you can also use the .. range operator:

#! /usr/bin/perl

@days = qw/Mon Tue Wed Thu Fri Sat Sun/;

@weekdays = @days[3..5];

print "@weekdays\n";

This will produce following result:

Thu Fri Sat
