# In the below exercises, write code that achieves
# the desired result. To check your work, run this
# file by entering the following command in your Terminal:
# `ruby if_statements.rb`

# Example: Using the weather variable below, write code that decides
# what you should take with you based on the following conditions:
# if it is sunny, print "sunscreen"
# if it is rainy, print "umbrella"
# if it is snowy, print "coat"
# if it is icy, print "yak traks"

weather = 'sunny'

case weather
when 'sunny'
  p 'sunscreen'
when 'rainy'
  p 'umbrella'
when 'snowy'
  p 'coat'
when 'icy'
  p 'yak traks'
else
  p 'good to go!'
end

# Experiment with manipulating the value held in variable 'weather'
# to print something other than 'sunscreen'

##################
# Using the num_quarters variable defined below, determine
# if you have enough money to buy a gumball. A gumball costs
# two quarters.

# Right now, the program will print
# out both "I have enough money for a gumball" and
# "I don't have enough money for a gumball". Write a
# conditional statement that prints only one or the other.

# Experiment with manipulating the value held within num_quarters
# to make sure both conditions can be achieved.

num_quarters = 0
if num_quarters >= 2
  puts 'I have enough money for a gumball'
else
  puts 'I don\'t have enough money for a gumball'

# Using the variables defined below, write code that will tell you
# if you have the ingredients to make a pizza. A pizza requires
# at least two cups of flour and sauce.

# You should be able to change the variables to achieve the following outputs:
# If cups_of_flour = 1 and has_sauce = true, print "I cannot make pizza"
# If cups_of_flour = 5 and has_sauce = false, print "I cannot make pizza"
# If cups_of_flour = 2 and has_sauce = true, print "I can make pizza"
# If cups_of_flour = 3 and has_sauce = true, print "I can make pizza"

# Experiment with manipulating the value held within both variables
# to make sure all above conditions output what you expect.

cups_of_flour = 1
has_sauce = true
if cups_of_flour >= 2 && has_sauce == true
  puts 'I can make pizze'
else
  puts 'I cannot make pizza'
