Looping Lab

The loop Construct

Objectives

1. Understand how the loop construct works

2. Build a method that utilizes the loop construct

Introduction

The first looping construct that we'll discuss is loop. This is the simplest looping construct that we have in Ruby. It simply executes a block (the code that is between the do and end keywords). Try this in IRB in your Terminal:

loop do
  puts "I have found the Time Machine!"
end

This will output I have found the Time Machine! an infinite number of times in your Terminal. Use Control+C to break out of the loop in your terminal.

Instructions

This is the first in a series of short exercises to help you get the hang of looping constructs.

1. There are no tests for this lab, so code your solution in looping.rb:

   • It's your first class in driving school and you're trying to remember important rules of the road. Fill out the content of the method looping to contain a loop that puts the phrase "Never pass a school bus if it has flashing red lights" an infinite number of times.

   • Beneath your method definition, call your method by typing the name of the method, looping.

2. Then, run the file by typing ruby looping.rb in your terminal from the directory of this lab. You'll be stuck in an infinite levitation loop! Hit Control+C to exit the infinite loop.
