Loop method for infinite loops in Ruby - Mini Project: Build & Apply

Loop Method for Infinite Loops in Ruby

📖 Scenario: You are creating a simple program that repeatedly asks a user for input until they type exit. This is useful for chatbots or menu systems that keep running until the user wants to stop.

🎯 Goal: Build a Ruby program that uses the loop method to create an infinite loop. Inside the loop, the program will ask the user to type something and will stop only when the user types exit.

📋 What You'll Learn

Use the Ruby loop method to create an infinite loop

Inside the loop, ask the user to type input using gets.chomp

Break the loop if the user types exactly exit

Print a message when the loop ends

💡 Why This Matters

🌍 Real World

Infinite loops are used in programs that wait for user commands or events, like chatbots, games, or menu systems.

💼 Career

Understanding infinite loops and how to control them is essential for software developers to build interactive and responsive applications.

1

Create a variable to store user input

Create a variable called user_input and set it to an empty string "".

Ruby

# Create a variable called user_input and set it to an empty string
# Your code here

Need a hint?

Use = "" to create an empty string.

2

Start an infinite loop using the loop method

Use the Ruby loop do syntax to start an infinite loop.

Ruby

user_input = ""
# Start an infinite loop using loop do
# Your code here

Need a hint?

Use loop do to start the infinite loop block.

3

Get user input and break the loop if input is 'exit'

Inside the loop do, write code to set user_input to gets.chomp. Then use break if user_input == "exit" to stop the loop when the user types exit.

Ruby

user_input = ""
loop do
  # Get user input and assign to user_input
  # Break the loop if user_input is exactly "exit"
  # Your code here
end

Need a hint?

Use gets.chomp to read input and break if to exit the loop.

4

Print a message after the loop ends

After the loop do block, write puts "Loop ended because you typed exit." to display a message.

Ruby

user_input = ""
loop do
  user_input = gets.chomp
  break if user_input == "exit"
end
# Print a message after the loop ends
# Your code here

Need a hint?

Use puts to print the message after the loop.
