Loops Worksheet

Read the code in each section, then write exactly what the code prints out. Use a loop table to help you track each variable for each iteration.

Each problem stands alone. Variables from previous problems do not exist.

Example:

x = 5
y = 6
print(x+y) #=> 11

Problem Set

2.times do
  puts "dance"
end

10.times do |i|
  puts i
end

3.times do
  puts "coding!"
end
puts "fun!"

5.times do |x|
  puts "#{x} chicken(s)"
end

10.times do |i|
  puts i * i
end

(1..5).each do
  puts "hello!"
end

(1..3).each do |i|
  puts "#{i} animals(s)"
end

(1..3).each do |i|
  puts i * i
end

total = 0

(1..3).each do |i|
  total = total + i
end

puts total

(1..10).each do |x|
  if x == 5
    puts "You got a winner!"
  end
end

i = 0

while i < 3
  puts "hi"
  i = i + 1
end

i = 0

while i < 3
  puts "hi"
  i = i + 1
end

puts "bye"

i = 0

while i < 3
  i += 1
  puts i
end

x = 5
i = 0

while i < 3
  x = x + 1
  i = i + 1
end

puts x

i = 3

while i > 0
  puts "ada!"
  i = i - 1
end

i = 1

while i
  puts "a while"
end

i = 1

while i < 100
  puts "o hai"
  i = i * 100
end
