Answer 1

Code is as follows:

Date.h

#ifndef DATE_H
#define DATE_H
#include<iostream>
using namespace std;

class Date
{
public:
Date();//default constructor
Date(int,int,int); //parametrized constructor
~Date(); //destructor
void setDate(int,int,int); //set date of the object
void displayDate(); //display the date

private:
int month; //private members of the class
int day;
int year;
};

#endif // DATE_H

Screenshot of the code:

FamousPeople.hFamous People.cpp main.cpp D ate. h Date.cpp 1 #ifndef DATE_H #define DATE H 3 #include<iostream> 4 using namespace std; 2 7- class Date { public: Date();//default constructor Date(int,int,int); //parametrized constructor Date(); //destructor void setDate(int,int,int); //set date of the object, void displayDate(); //display the date private: int month; int day; int year; //private members of the class 21 #endif // DATE_H
