(3)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。
