NumDays Class

Design a class called NumDays. The class's purpose is to store a value that represents a number of work hours and convert it to a number of days. For example, $8$ hours would be converted to $1$ day, $12$ hours would be converted to $1\mathrm{.}5$ days, and $18$ hours would be converted to $2\mathrm{.}25$ days. The class should have a constructor that accepts a number 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. $($C$++$ language, use comment headers in every line$)$
