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,
- We have an array of strings named
str_array
containing string representations of integers. - We use the
map
method to transform each element ofstr_array
to an integer usingto_i
. - The resulting array
int_array
contains the converted integers. - 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]
