枚举类型和变量如何定义，下篇博客讲得十分详细：
https://blog.csdn.net/bruce_0712/article/details/54984371
有几个需要注意的点：
（1）在不进行强制类型转换的前提下，枚举量只能由枚举类型赋值。但是，可以把枚举量赋给其它类型（枚举量被强制转换为整型）。
（2）枚举量没有赋初值的话，会自动从0开始，按从小到大的顺序，以整数的形式初始化。
即
enum enumType {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday};
Monday~Sunday 会默认为0~6。将其中某个赋初值的话，下一个枚举量也会自动向上递增。
（3）枚举类型常和switch分支搭配使用。
自己简单练习了一下。用户输入0-5的数字来选择工作日，输出当天的安排。
