How to Convert an Array of Strings to an Array of Integers in Ruby - Step by Step Examples



How to Convert an Array of Strings to an Array of Integers in Ruby ?

Answer

To convert an array of strings to an array of integers in Ruby, you can use the `map` method along with `to_i` to perform the conversion.



✐ Examples

1 Convert Strings to Integers

In this example,

  1. We have an array of strings named str_array containing string representations of integers.
  2. We use the map method to transform each element of str_array to an integer using to_i.
  3. The resulting array int_array contains the converted integers.
  4. We print the contents of int_array to demonstrate the conversion.

Ruby Program

str_array = ["10", "20", "30"]
int_array = str_array.map(&:to_i)
puts "Converted array of integers: #{int_array}"

Output

Converted array of integers: [10, 20, 30]
