1.优化购物程序,购买时允许用户选择购买多少件,
2.允许多用户登录,下一次登录后,继续按上次的余额继续购买 ,可以充值 (每个用户有独立的保存文件)
3.允许用户查看之前的购买记录(记录要显示商品购买时间)
4.商品列表分级展示,比如:
第一层菜单:
1.家电类
2.衣服类
3.手机类
4.车类
...
选择一个,车类,进入第2层
1。BMW X3 33333
2.Audi Q5 33333
3.Pasate 33335
4.Tesla Model_3 430000
5.Tesla Model S 888888
5.显示已购买商品时,如果有重复的商品,不打印多行,而是在一行展示,如
id p_name num total_price
1. TeslaModelS 2 3434343434
2. Coffe 2 60
3. Bike 1 700
