Write your question here.

Design and implement the class Day that implements the day ofthe week in a program. The class Day should store the day,such as Sun for Sunday. The program should be able to performthe following operations on the object of type Day:
a. set the day
b. print the day
c.return the day
d.return the next day
e. return the previous day
f. calculate and return the day by adding certain days to the current day.. Such as if today is monday and we add four daysit will return Friday
g. add the appropriate constructors
h.write the definitions of the methods to implement a -g
i.write a program to test the operations of class Day.

i have this codes but i cant make the previous, next and adding days methods to work
