How to Iterate Over an Array in Ruby - Step by Step Examples

How to Iterate Over an Array in Ruby ?

Answer

To iterate over an array in Ruby, you can use methods like each or for loops.


✐ Examples

1 Iterate Over Integer Array with each Method

In this example,

  1. We create an integer array named numbers with some values.
  2. We use the each method to iterate over each element of the array and print the elements.

Ruby Program

numbers = [1, 2, 3, 4, 5]
numbers.each do |num|
  puts num
end

Output

1
2
3
4
5

2 Iterate Over String Array with for Loop

In this example,

  1. We create a string array named fruits with some values.
  2. We use a for loop to iterate over each element of the array and print the elements.

Ruby Program

fruits = ["apple", "banana", "cherry"]
for fruit in fruits
  puts fruit
end

Output

apple
banana
cherry
