Arrays and Hashes

Introduction to Perl Arrays

• A Array is simply a collection of scalar data with a specified order.
• Arrays can be as short as zero elements (empty), or have as many elements as system memory permits.
• An array element can store any legal scalar data.
• An array can be thought of as an ordered list of scalars.
• A particular scalar in an array is identified by an integer index.
• Array indexes start at 0 (not 1).
• In Perl, the terms array and list mean exactly the same thing.
