this is my assignment:
Description: We are interested to develop a Costumer Management System for a company, which stores customers and orders information and helps system user to search, edit, and enter data. Each customer has a CustomerNumber (ID), Name, Address, and Phone which can be stored in a list such as [1, “Amin Milani Fard”, “Columbia College”, 778]. Each order has an OrderNumber, CostumerNumber, OrderDate, and OrderedItemsList such as [5,1,”20/06/2011”, [“XYZ”, “ABC”, “LMNOP”]].
将向您提供两份投入文件,即客户。 载有成本计数和订单的吨位。 载有命令清单的txt。 首先,你们需要阅读投入文件,然后根据用户选择适用搜索、编辑、添加或删除客户和(或)订单清单。 您的方案应当重复显示一个菜单,因为用户没有进入9台,所以:
**** Welcome to My Customer Management System ****
Please select an option
1. Load the input files
2. Search a customer
3. Search an order
4. Add a new customer
5. Add a new order
6. Delete a customer
7. Delete an order
8. Save data in files
9. Quit
在档案中保存数据有问题,即只想获取数据。 我想到的是,在选择4时,将自动节省费用。 是否有办法从猪肉中拯救一只 t子?
