Design and implement a class dayType that implements the day of the week in a program. The class dayType should store the day, such as Sun for Sunday. The program should be able to perform the following operations on an object of type dayType:  Set the day.  Print the day.  Return the day.  Return the next day.  Return the previous day.

Assigment #3 Q#1

Design and implement a class dayType that implements the day of the week in a program. The class dayType should store the day, such as Sun for Sunday. The program should be able to perform the following operations on an object of type dayType:

  Set the day.

  Print the day.

  Return the day.

  Return the next day.

  Return the previous day.

Calculate and return the day by adding certain days to the current day.

For example, if the current day is Monday and we add 4 days, the day to be returned is Friday. 

Similarly, if today is Tuesday and we add 13 days, the day to be returned is Monday.

  Add the appropriate constructors.
