Answer 1

这个类是在NODEPAD中临时写的,没有测试过,有些因为懒,就没有写全,不过基本上应该都写出来了,请楼上测试一下,有的地方改一下,有的地方完善一下,应该没有问题

Answer 2

还有开始还是运行N个PUSHRATE函数,因为懒,所以没有把它们PUSH进去

Answer 3

很明显的错误,不过,只要思路对就行了,我没有改啊,你自已改吧,只是在NODEPAD中下午花了几分钟时间粗粗的设计了一下

Answer 4

CALCULATE 计算个人所得税,如果扣除后金额大于最后一个税额,则用最大的税率和最大速算扣除数,
PUSHRATE 增加一个税率,如果税额相同,则不增加,直接修改相应的税率和速算扣除数,按税额大于排序,
POPRATE 删除一个税率,如果找到指定的税额,则予以删除,否则不变,还是按税额大于排序

Answer 5

楼上,呵呵<提问>按钮就行了
