Ruby Arrays Programs

In Ruby, arrays are ordered, integer-indexed collections of any object. The indexing of an array starts at 0. A new array can be created by using the literal constructor []. Arrays can contain different types of objects. For example, the array below contains an Integer, a String and a Float.

This section contains Ruby arrays programs, practice these Ruby programs to learn the concept of Ruby arrays, these programs contain the solved code, outputs, and the detailed explanation of the statements, functions used in the Ruby arrays programs.
