The problem sounds simple: create a program accepting inventory input from the user (vitamin name, quantity, price) that will display the input in columns as well as calculate grand totals.
I understand using set to create columns, and how to calculate totals. My question is...where do I start? I'm not sure how to accept unlimited amounts of input (i.e. how do I name variables when they could be unlimited in number?)
We haven't yet discussed classes, so using anything before that is acceptable (functions, switches, arrays, strings).
