运算符重载枚举 [英] Operators overloading for enums

问题描述

是否可以定义枚举的运算符？例如我有我的班级的枚举月份，我希望能够编写++ my_month。

谢谢

PS

为了避免溢出我做了这样的事情：

Is it possible to define operators for enums? For example I have enum Month in my class and I would like to be able to write ++my_month.
Thanks
P.S.
In order to avoid overflowing I did something like this:

void Date::add_month()
{
    switch(my_month_)
    {
    case Dec:
        my_month_ = Jan;
        add_year();
        break;
    default:
        ++my_month_;
        break;
    }
}

推荐答案

是它是。操作符重载可以对所有用户定义的类型进行。包括枚举。

Yes it is. Operator overloading can be done for all user defined types. That includes enums.
