How to Declare an Integer Array in Ruby

How to Declare an Integer Array in Ruby ?

Answer

To declare an integer array in Ruby, you can use array literal notation or the Array.new constructor.


✐ Examples

1 Declare and Initialize an Integer Array

In this example,

  1. We declare an integer array named numbers with predefined values using array literal notation.
  2. We print the array to demonstrate the initialization.

Ruby Program

numbers = [1, 2, 3, 4, 5]
puts "Integer Array: #{numbers}"

Output

Integer Array: [1, 2, 3, 4, 5]

2 Declare an Empty Integer Array

In this example,

  1. We declare an empty integer array named empty_array using the Array.new constructor.
  2. We print the array to demonstrate the declaration.

Ruby Program

empty_array = Array.new
puts "Empty Integer Array: #{empty_array}"

Output

Empty Integer Array: []
