分享thoughtworks面试题
今天去面试，公司给我用email发了到题，我不太会做，大家一起看看吧。(要求用C++是实现)
PROBLEM TWO: SALES TAXES
Basic sales tax is applicable at a rate of 10% on all goods, except books, food, and medical products that are exempt. Import duty is an additional sales tax applicable on all imported goods at a rate of 5%, with no exemptions.
When I purchase items I receive a receipt which lists the name of all the items and their price (including tax), finishing with the total cost of the items, and the total amounts of sales taxes paid. The rounding rules for sales tax are that for a tax rate of n%, a shelf price of p contains (np/100 rounded up to the nearest 0.05) amount of sales tax.
Write an application that prints out the receipt details for these shopping baskets...

[Quote=引用 10 楼 的回复:]
对于第三个里面的 1 box of imported chocolates at 11.25 为什么我算出的Tax是0.55而不是0.6
11.25*0.05 = 0.5625 按照题中说的算法，Round下是0.55……加出来是 1180 而不是结果中的 11.85
[/Quote]
是11.85,而且就算按你的算法应该是11.81

对的
里面有句话,你们没找到
我也收到邮件了但是没通过...
ThoughtWorks考的是面向对象,纠结字符串你就错了

且不评论这道题怎么设计，首先给的测试数据就有问题，比如
1 imported bottle of perfume at 47.50，输出应为54.63；
1 box of imported chocolates at 11.25，输出应为11.81.
应该不对吧！

看来计算还算简单，主要是处理字符串了。像4楼的发现输入的格式读取物品和价格。

只是计算商品的价格和价格构成(原价+tax+Import duty )

一项:
数字 物品 at 价格 换行
物品:
任意字符(空格 任意字符)*
其实还是很简单的嘛,这还像个面试题,不像某些公司搞得这么装逼..问什么加油站有多少,汽车多少之类的.搞得像是脑筋急转弯

把文本tokenize成number whitespace what_good whitespace at whitespace price
然后建立 物品 和 种类 的table,剩余的就容易了
