ISC 2020 program class convert

isc 2020 program Design a class Convert to find the date and the month from a given day number for a particular year. Example: If day number is 64 and the year is 2020, then the corresponding date would be: March 4, 2020 i.e. (31 + 29 + 4 = 64).Some of the members of the class are given below:

Class name: Convert
Data members/instance variables:
n: integer to store the day number.
d: integer to store the day of the month (date).
m: integer to store the month.
y: integer to store the year.
Methods/Member functions:
Convert(): constructor to initialize the data members with legal initial values.
void accept(): to accept the day number and the year.
void dayToDate(): converts the day number to its corresponding date for a particular year and stores the date in ‘d’ and the month in ‘m’.
void display(): displays the month name, date and year.

Specify the class Convert giving details of the constructor, void accept(), void dayToDate() and void display(). Define a main() function to create an object and call the functions accordingly to enable the task.

        d=n;
