软件工程个人作业02

一：设计思想
1、题目避免重复：将数放入数组，利用数组进行比较（第1个和2.3.4……n比较，然后第2个跟3.4.5……n比较，……，以此类推）
2、可定制（数量/打印方式）：添加语句，设置数量
3、可以控制下列参数:
是否有乘除法：有，则调用全部的符号，无，则调用仅加减符号
是否有括号(最多可以支持十个数参与计算)：还没有思考好（还没有来得及实现）
数值范围：需要数值有范围的，在调用的时候添加变量；不需要有范围的，直接使用默认的范围
加减有无负数：默认没有，需要的话可以指定范围，然后自动生成
除法有无余数：把除数和被除数放在两个数组内，然后相应位数进行取余运算（还没有来得及实现）
