Answer to Question #330462 in C++ for mak

Question

Write a program to implement the Date class which has three data members named day, month and year.

 

1.  Provide a constructor, which takes arguments (you may set values of data members to 0).

 

2.  Write getter and setter functions (input and show functions) for the Date class.

3.  Also write a member function void CompareDates(Date d1, Date d2) which tells which date comes first.

Answer 1

#include <iostream>
#include <iomanip>
#include <string>

class Date
{
private:
unsigned day;//Day of month

public:

//Implement getters
unsigned getDay()const;
unsigned getMonth()const;
unsigned getYear()const;
//Sets
void setDay(unsigned d);
void setMonth(unsigned m);
void setYear(unsigned y);
//print method
void Print();
void CompareDates(Date d1,Date d2);//Compare two date
};
