Hello, Please help. Below is my assignment and the code I've got so far. I'm still getting errors on overloading the member function on the printDay and prevDay.
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.
-Then, write the definitions of the functions to implement the operations for the class dayType as defined in Programming above. Also, write a program to test various operations on this class.
