FidMe Ruby challenge

This small exercice is just meant to challenge new FidMe appliants.

Get started !

• Clone this repo (do not fork it)
• Install ruby if you haven't (any version will do fine)
• Run ruby main.rb --loyalty_card_id=1 --user_id=5

The challenge

We are building a wallet app. Let's call it FidMe !

Our wallet app is made of a few identities: For now we have users and loyalty cards.

Users can own loyalty cards. Users can gain rewards (points) for a given card.

We already have a few data at our diposal (see input.json) and a main program (see main.rb)

The problem is... the command ruby main.rb --loyalty_card_id=1 --user_id=5 always returns the same value !!

Write code that reproduces the output of the command, but is actually working with input.json data.

What we expect from you

• Take your time :)
• Produce what your consider to be clean code.
• Use object oriented programming
• Do not try to overthink it
• Use any library or tool that you want (except Rails ;) ).
• You can create files and folders if you want
• You can (and we would love if you do) write test (but it is ok if you are not confident with it).
