蛋疼的ACM

= =重庆市的ACM比赛，规模估计比不上别的市，问题是还是要培训，今天写了道蛋疼的题

 

Description:

计算机经常用于工资和帐号支付应用等支票写入系统。许多怪事常常出现。如每月工资支票上错误的多写一百万美元。由于人和机器的错误，使支票写入系统写出不正常数值。系统设计人员在系统中建立控制，防止发生出这种错误支票。另一个严重的问题是有些人故意改变支票金额，想窃取钱财。要防止改变支票金额，大多数支票写入系统采用支票保护（Check Protection）技术。一个常用的安全方法是写出支票金额的大写，即使支票的数字好改，大写金额也难篡改。编写一个程序，输入数字金额，输出大写金额。如112.43写成ONE HUNDRED TWELVE Dollars and 43/100。

Input:

输入数据有若干，数据范围在0.00到999.99。

Output:

对于每个数据输出其大写的英语表示。如12.45写成TWELVE Dollars and 45/100。如果是整数部分是零或一美元，则Dollar不加s。如果没有角分，则角分不用输出。

Sample Input:

0.45

34

56.89

Sample Output:

ZERO Dollar and 45/100

THIRTY FOUR Dollars

FIFTY SIX Dollars and 89/100

 

代码如下

坏习惯改不了了…………老是不习惯写成函数…………每次都是直接堆到主函数里= =不过我有接口，函数调用需要时间，比赛是有时限的。不过其实可以弄成内联函数的= =
