# 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"

if weather == "sunny"
  p "Tshirt and shorts"
elsif weather == "rainy"
  p "umbrella"
elsif weather == "snowy"
  p "coat"
elsif weather == "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 == 0
  p "I don't have enough money for a gumball"
elsif num_quarters == 2
  p "I 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.
