把数字转换为人民币大写(用于银行系统)

大二是老师让做一个综合试验::用C++实现简易银行系统,其中用到在打印流水账时要求把金额转换为人民币大写...当时傻里吧唧的,,,随便拷贝了个同学的应付老师交了了事...前一段一个大二的弟兄向我提起银行程序..问起金额转换,起初心想要处理零零等问题麻烦,结果一个同学说四位,四位处理,OK..豁然开朗,顺利完工

今天上午快十点起来,抄了几份试验报告,下午自习看了云风的<游戏之旅--我的编程感悟>..晚上团契祷告会,我刚回来,,今天就把前2天的个程序发布下吧!!
还有个问题处理小数点..按说找到小数点位置在分割开处理就可以啦,.没弄.弄了在发布吧!!现在不想编程,,,想随便转转,看看云风去!!!!(决定以后只要看本专业相关的书,不管受益多少,都要总结下)今下午的当然不例外哈!!!
