Project landed me a job at Ministry of Justice so success? Archiving because it's nice to look back on where I were and where I am now

This repo contains the code behind powering the checkout system at the local shopping mall.

Below are the instructions on how to run the app and how some of the files work

• Running the app
• How the file structure works

• products.csv - This file contains the Product Code, Name, and Price of a certain product
• discounts.csv - This file contains any discounts to be applied to products.

Explanation: If a product is buy one get one free then the discount applies as soon as you have two items or more therefore it will apply from the start

To run the app you can just run the binary in your console. In the root of the project just do ./shopping-mall.

Or if you have Go installed you go use the standard Go commands like run or build

go run ./cmd/cli/main.go --products=./files/products.csv --discounts=./files/discounts.csv

We have 2 flags to customise the location of where the products.csv file and the discounts.csv file found the defaults are listed below.

Usage of ./shopping-mall:
  -discount
    	location of the discount list(default "files/discounts.csv")
  -product
    	location of the product list (default "files/products.csv")

This project comes with 2 csv files for reading in a list of products and a list of discounts. The structure of these files are important for how the information is read into the app so we've laid it out below

products.csv file structure

Based on the table above this is how the CSV file should be structured

FR1,Fruit Tea,3.11
SR1,Strawberries,5.00
CF1,Coffee,11.23

discounts.csv file structure

Based on the table above this is how the CSV file should be structured

FR1,3.11,yes,0,Buy one get one free
SR1,0.50,no,3,Buy 3 or more for a reduced price of £4.50
