How to Declare an Array in Perl Functions

Perl includes useful programming features.

Perl is an open-source language that enables you to program on various platforms, including Unix, Mac and Windows. Arrays are a programming construct that enables you to store lists or related content. Perl arrays are defined with a preceding "@" sign. Each element is contained within a parenthesis and separated by commas. Insert string data within quotes and numerical data without the quotes.

Instructions

1. Open your Perl document in a Perl or text editor.

2. Type the following code to define a numerical array:

   @nums = (1,20,3,45);

3. Type the following code to define an array that contains strings:

   @mystr = ("me","myself","I");

4. Insert the following data to define an array consisting of numbers and strings:

   @alphanum = ("once",5,"always",2,6);
