人民币金额数字转中文大写程序多种编程语言汇总2011版

        这里目前给大家提供的是PHP，JSP（JAVA），ASP（VB6），JAVASCRIPT，VC++，Python，ActionScript3.0， VB.Net，C#  等语言的版本.

        网上搜索一下：你要的编程语言名称，再加上“人民币 数字 金额 转大写 汉字”，结果就会出来异常多的结果。所以，这种代码已相当烂了，到处都有。什么语言的都有。到处都有的代码，你为什么要重造轮子？没办法呀，我实在不能用那些无法维护的代码。尽管我的代码写得不算是最好的，但总要有一个象样的代码，我才安心！！
        很多人都在讲程序高手。其实高手就在于相当简单的基本功上。比如，你的for循环用得如何？你的if用得怎样。当然，早年用VB的人，if用得肯定好。因为，VB没有continue，你不得不反向思维，写好if。
        其实高手还有另一个关键点，那就是程序如何写。所有高手都擅长预处理数据，从而使得程序不会跟着数据跑。在这一前提下，任何一个问题，众多高手的写出来的代码流程均是相似的。而普通程序员则会千差万别。
        比如现在网上的人民币金额转大写程序，任何语言，你都不能找到一个满意的版本。也有人甚至说，这个算法，绝对不可能在30行以内完成（指PHP）。
        好久不写其它编程语言的代码了，接下来，会用到这样的程序。所以，作为一个伪高手，技术不是怎样的我，写出一个版本，PHP代码竟然只有21行。所以，决定分享给大家。觉得给初学者指一个路，看看if, for该当如何使用。（从PHP说，这个代码中如果if用不好，则会多出几个continue和至少一个break。另外，如果不注意使用数学方法，与预定义变量的配置，还会多出好几个if，当然，这并不算优秀的代码，仅供参考！！）
        其实，如果你仔细看一下代码，你就会发现，经过数据预处理后，将算法中有if全部集中起来了，并且能将其嵌入到循环中了。由此可见，先将数据处理成程序方便处理的格式，程序中就会少掉大量的代码。预处理数据后，程序不会跟着数据走。这一点在我公开课《数据处理算法设计要点》（链接中的网址是首发网址，百度文库未经许可，属于抄袭。当然，这个盗版人稍有一点人性，不象《PHP程序员必须掌握的PHP面向对象的特有的特性》盗版人，抹去了所有原作者去出处信息！！）中已经讲过。有心人可以在网上搜索到。所以，不多讲了。

        另外有一点，我们可以看出，PHP的代码行数是最少的。用好了PHP的人都了解，远比JAVA精简多了。比如，本函数中的数据预处理，PHP因为拥有sprintf，因而仅需一行代码。但JAVA却绕了相当大的弯子。从这一点来讲，PHP是造就优秀程序员的语言。而JAVA则是让傻瓜使用的语言。VB就更不用说了，完全是面对门外汉的。（个人看法，不用当真。当真你就输了！）

        其次，很多版本的，真正按汉语习惯，或者说真正按数字读法完全正确的写出的并不多。比如，302000，应当是叁拾万贰仟。但却有叁拾万零贰仟的版本。而300200应当是叁拾万零贰佰，却也有叁拾万贰佰的版本。所以，写代码的人，首先对汉语数字正确的读法都不清楚。
        这个函数是支持16位整数的。但是对于万亿，仍用的是万，因为，无法用兆，兆在当今是10的6次方，不再是12次方了。如果你不习惯，直接将第一个万改成万亿即可。
        要注意的是，32位机中，大数字会溢出，对于PHP，直接传入字串形式的测试。
        当然，目前还缺象C++,  Ruby的版本。如果有有兴趣完成，别忘了发给我，我会加进来，当然，程序中一定是暑你的大名了。

        网上代码，搜索出来的是什么样子？看一看好心人保存下来的我在2002年完成的代码大家可能就了解了。虽然，函数使用，流程处理的功夫上已不低，但还没有懂得，如何进行预处理。程序是完全跟着数据走的。那时，在大家看来是最好的VB代码了。可现在我看，仍然是很差的代码，因为，同下面现在写的代码比一下，行数更少。程序逻辑更加清析。2002年的代码的网址如下：
