设计佣金问题的程序

commission方法是用来计算销售佣金的需求，手机配件的销售商，手机配件有耳机（headphone）、手机壳（Mobile phone shell）、手机贴膜（Cellphone screen protector）三个部件，每个部件单价为：耳机80元，手机壳10元，手机贴膜8元，每月月末向制造商报告销量，制造商根据销量给销售商佣金。如果销售额不足1000元按10%提取佣金，1000-1800元部分按15%提取佣金，超过1800元部分按20%提取佣金。

程序要求：

1）先显示“请分别输入三种手机配件的销售情况：”

2）不满足条件，返回：“输入数量不满足要求”，返回重新输入；

3）条件均满足， 则返回佣金额。返回等待输入。
