Using C++ 11 Design a class called NumDays. The class’s purpose is to store a value that represents a number of work hours and converts it to a number of days. For example, 8 hours would be converted to 1 day. 12 hours would be converted to 1.5 days, and 18 hours would be converted to 2.25 days. The class should have a constructor that accepts a member of hours, as well as member functions for storing and retrieving the hours and days. The class should also have the following overloaded operators:   +   Addition operator. When two NumDays objects are added together, the overloaded +     operator should return the sum of the two objects’ hours members.  -     Subtraction operator. When one NumDays object is subtracted from another, the overloaded – operator should return the difference of the two objects’  hours members.  ++     Prefix and postfix increment operators. These operators should increment the          number of hours stored in the object. When incremented, the number of days should        be automatically recalculated.  --     Prefix and postfix decrement operators. These operators should decrement the number of hours stored in the object. When decremented, the number of days    should be automatically recalculated.
