Ruby - Find the Length of a String

1. Introduction

A string's length represents the number of characters it contains. Determining the length of a string is a frequent requirement in various programming tasks. In this tutorial, we'll learn how to find the length of a string in Ruby.

2. Program Steps

1. Set up the Ruby development environment.

2. Prompt the user to enter a string.

3. Use thelength method to find the number of characters in the string.

4. Display the length of the string to the user.

3. Code Program

# Prompt the user to enter a stringputs "Enter a string:"input_string = gets.chomp# Determine the length of the stringstring_length = input_string.length# Display the length of the string to the userputs "The length of the string is: #{string_length}"

Output:

Enter a string:Hello, World!The length of the string is: 13

Explanation:

1.gets: Captures user input.

2.chomp: Removes the newline character from the user input.

3.length: This method returns the number of characters in a string, including spaces and punctuation.

By employing thelength method from Ruby's String class, we can efficiently ascertain the number of characters in a string.
