#Working. Need to determine how to figure out if user is entering garbage data (strings not numbers). Maybe Regex? | |
#Also need to put in a rescue for divide by 0 error. | |
#Require pry for debugging | |
require 'pry' | |
#Method to get user input | |
def get_input msg | |
puts "***** #{msg} *****" | |
end | |
#Method to handle operations | |
def operate num1, num2, oper | |
o = case oper | |
when 1 | |
result = num1.to_i + num2.to_i | |

when 2 | |
result = num1.to_i - num2.to_i | |
get_input "The solution is #{result}" | |
when 3 | |
result = num1.to_i * num2.to_i | |
get_input "The solution is #{result}" | |
when 4 | |
