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 the length 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 string
puts "Enter a string:"
input_string = gets.chomp
# Determine the length of the string
string_length = input_string.length
# Display the length of the string to the user
puts "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 the length method from Ruby's String class, we can efficiently ascertain the number of characters in a string.
