Define a Date class containing three private attributes day, month, and year.

Provide this class with a constructor allowing the initialization of its attributes. Date$($int$,$int,int$)/$You have to assign a default arguments for all parameters and deal with it ;

Provide a set and a get method for each data member.

Define a class named Doctor which has $4$ Data members

Doc Name: a string type

patient Names: a string array with a unlimatied size $,$ use it to save patient names $.$ "dynamic array"

patient num: an integer type. represent the number of patient currently.

salary: a double data type

and methods:

Default constructor to the class,with patient$\_$num$=0,$maximumnumberof patient $=10.$

a constructor Doctor $($string doctorname, int maximumnumberof patient,double salary$),$ You have to assign a default arguments for all parameters and deal with it ;

a method that displays an object's information. void printInfo$()$;

a method to add patient' names. void addpatient names$($string newpatientname$)$;

Set and get methods for Doc$\_$Name and Salary data members. $($create set method to ensure the Doc Name data member contains a valid value; further assign a salary value that is positive$)$

create a copyObject methode, void copyObject$($Doctor anotherObject$)//$ that copy values of data members in another object to the corresponding data members in the current object.

Write your class in a separate file $($interface & implementation files$),$ you have to use a preprocessor directive.

Test your software in the main function:$($open deriver file main.cpp$)$

Creates two Doctor object named D$1,$D$2.$

add patient names to the D$1$ object, use the $($addpatient names method$).\{$Amal$,$ Salwa,Deem$\}$

copy the values of D$1$ to D$2,$ using copyObject Method.

print the details of the D$2$ object.
