perl data structures tutorial - part1

Perl provides a rich set of data structures that can be used to store and manipulate data. In this tutorial, I'll cover the most commonly used data structures in Perl, along with code examples.

Arrays

Arrays are ordered lists of scalar values. To declare an array, you use the @ symbol followed by the array name. Here's an example:

@my_array = (1, 2, 3, 4, 5);

You can access individual elements of the array using the array name followed by the index of the element in square brackets. Here's an example:

print $my_array[0];  # prints 1

You can also use the scalar function to get the number of elements in an array:

print scalar(@my_array);  # prints 5
