#Discount System.
You are asked to write a discount system for a saloon, which provides service and sells beauty products. It offers 3 types of memberships Premium, Gold and Silver members receive a discount of 20%,15% and 10% respectively. For all services provided customers without memberships receives no discount. All members receive a flat 10% discount on product purchased (that might change in future)
#Project Analysis:
This project for a Saloon Discount system that provides services and sells beauty products. So firstly, we need to store those available services and products for saloon serves customers. So, we have needed two separate classes for services and beauty products which required member variables and functions. Now focus on customers membership, every customer is a member, So we need a class member then we separate members to different memberships like as Premium, Gold, Silver and General member. This all-different membership is a separate class that contains different discount percentages.
#Membership criteria
If a member deposits 7,000 BDT, then he gets Premium membership. When he purchased a service, he gets 20% discount on that service's price.
If a member deposits 5,000 BDT, then he gets a Gold membership. When he purchased a service, he gets 15% discount on that service's price.
If a member deposits 3,000 BDT, then he gets Silver membership. When he purchased a service, he gets 10% discount on that service's price.
Otherwise, members do not get any membership and discount when they purchased any services. But all member who bought of any beauty products he gets a flat discount from that product price, that’s why we need a flat discount class. If the authority wants this flat percentage discount to be changeable in the future.
