Say it in English

Write a program that will take a number from 0 to 99 and spell out that number in English.

In other words, if the input to the program is 22, then the output should be 'twenty-two'

e.g.

Say.new(22).in_english

Say.new(-1).in_english
# say.rb:7:in 'in_english': Number must be between 0 and 99, inclusive. (ArgumentError)

The program must also report any values that are out of range.

• 0
• 14
• 50
• 98
• -1
• 100
