  2. We print the array elements to the console to demonstrate the initialization.

Ruby Program

string_array = ["Hello", "World", "Ruby"]
puts string_array

Output

Hello
World
Ruby

2 Declare an Empty String Array

In this example,

  1. We create an empty array named empty_string_array.
  2. We add string elements to the array and then print the array elements to the console to demonstrate the declaration.

Ruby Program

empty_string_array = []
empty_string_array << ""
empty_string_array << ""
empty_string_array << ""
puts empty_string_array
