#I’d like to run a program to check whether a person can enter a pub or not. How to do this? Is my code enough?

age = 18
if age > 18
puts “You can enter the pub”
elsif if age == 18
puts “Great! You’re finally ready to enter our place! We’d like to greet you with a free pint of beer!”
else
print “You’re not allowed to enter the pub, I’m sorry!”
end

Why am I unable to get my code to identify when (2) negative integers are chosen (versus just (1))… please help.

My multiplication routine :slight_smile:

puts “Here is my multiplication routine:”
puts “Pick an integer”
my_value = Integer(gets.chomp)
puts “Pick another integer”
my_value2 = Integer(gets.chomp)

if my_value < 0 || my_value2 < 0
puts “You picked a negative integer…\n”
elsif my_value <= -1 && my_value2 <= -1
puts “You picked both negative integers…\n”
elsif my_value == 0 || my_value2 == 0
puts “You know the product of anything multiplied by zero is ZERO right?!?!\n”
else my_value > 0 && my_value2 > 0
puts “Great we have 2 positive integer(s)…\n”
end

product_value = my_value * my_value2

puts “The product of ‘#{ my_value}’ and ‘#{ my_value2}’ is equal to ‘#{ product_value}’”

I figured it out! :slight_smile:
Just for reference for anyone else - the order is just as important (since you’re essentially cascading down from top to bottom (which should be obvious, but just following the tutorial step by step didn’t immediately make that clear for me).

For example:
First) my_value <= -1 && my_value2 <= -1
puts “You picked both negative integers…\n”
Second) my_value < 0 || my_value2 < 0
puts “You picked a negative integer…\n”
