Loop method for infinite loops in Ruby - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create an infinite loop using the loop method.

Ruby

loop do
  puts "Hello, world!"
  [1]
end

Drag options to blanks, or click blank then click option'

Abreak

Bexit

Dnext

💡 Hint

Common Mistakes

Using 'break' will stop the loop immediately.

Using 'exit' will stop the entire program.

The next keyword skips to the next iteration, so the loop continues infinitely.

medium

Complete the code to print numbers from 1 to 5 inside an infinite loop, then break the loop.

Ruby

i = 1
loop do
  puts i
  i += 1
  [1]
end

Drag options to blanks, or click blank then click option'

Aredo if i > 5

Bnext if i > 5

Cbreak if i > 5

Dexit if i > 5

💡 Hint

Common Mistakes

Using 'next' will skip the rest of the iteration but not stop the loop.

Using 'exit' will stop the whole program, not just the loop.

The break if i > 5 stops the infinite loop after printing numbers 1 to 5.

hard

Fix the error in the code to create an infinite loop that prints 'Looping'.

Ruby

loop [1]
  puts 'Looping'
end

💡 Hint

Common Mistakes

Using 'while true do' after 'loop' is incorrect syntax.

Using 'for' is not valid with 'loop'.

The correct syntax for an infinite loop using the loop method is loop do.

4fill in blank

hard

Fill both blanks to create an infinite loop that prints 'Tick' every second.

Ruby

loop [1]
  puts 'Tick'
  sleep [2]
end

Drag options to blanks, or click blank then click option'

D0.5

💡 Hint

Common Mistakes

Using 'while true do' after 'loop' is incorrect syntax.

Using 'sleep 0.5' will pause for half a second, not one second.

The loop do syntax creates an infinite loop, and sleep 1 pauses for one second each iteration.

5fill in blank

hard

Fill all three blanks to create an infinite loop that counts from 1 upwards and breaks after 10.

Ruby

count = [1]
loop [2]
  puts count
  count += [3]
  break if count > 10
end

Drag options to blanks, or click blank then click option'

D10

💡 Hint

Common Mistakes

Starting count at 1 will print 1 to 11 instead of 1 to 10.

Using 'while true do' instead of 'do' after 'loop' is incorrect.

Start counting at 0, use loop do for the infinite loop, and increase count by 1 each time.
