Shopping Cart Calculator

How to run

This program accepts SKUs from standard input. Each line should contain a single SKU. On end of file, the program will print the total price of the cart.

First, build the executable with:

go build

I've included a sample input file that you can test like so:

cat example.txt | ./ThinkMoneyCheckout

Alternatively you can type in items interactively, then press CTRL+D to send an EOF.

Running tests

go test cart/cart_test.go

Adding new SKUs and deals

SKUs and deals are defined in main.go. You can add new SKUs and deals by adding them here:

You can also implement different types of deals, so long as they implement the Deal interface defined in cart.go.
