人民币金额大写问题
从键盘输入一个十亿以内的正整数（int类型），把它转换为人民币金额大写
比如
用户输入：30201，程序输出：叁万零贰佰零壹
用户输入：30001，程序输出：叁万零壹
用户输入：31000，程序输出：叁万壹仟
用户输入：120023201，程序输出：壹亿贰仟零贰万叁仟贰佰零壹
用户输入：120020001，程序输出：壹亿贰仟零贰万零壹
用户输入：100000001，程序输出：壹亿零壹
在万后满千位，则不加零，否则要补零，但不要出现类似“零零”的情况。
在亿后满千万位，则不加零，否则要补零，但整个“万档”没有数字时，“万”字省去。

我以前写了个简单的，给你找出来了，支持13位，checkinput做得不好，你拿去改一下。
