Problem with Overloaded Constructors and Class within Class
I am trying to create an instance of a class within a class (Date within CPPTicket), and trying to overload constructors with the date info. When the program runs, I am calculating the correct date (I have testing couts showing the right date and dayofyear), but when I call my GetDayOfYear() function, it is assigning the same date to both instances of my Date class. I can't figure out what I'm doing wrong. I am not getting any errors, but the program is not working as anticipated. The code is below:
//date.h
//Jerry Brinegar - BringerQ6
//Date.h
#ifndef _DATE_H
#define _DATE_H
#include <string>
using namespace std;
class Date
{
private:
int month, day, year;
string description;
int DayOfYear;
void CalculateDayOfYear();
public:
Date(); //constructor object with system date 7/5/2006
Date(int m, int d, int y, string desc); //constructor for input values
void SetDate(int m, int d, int y, string dsc);
//sets Date object to input values
string GetFormattedDate();
//returns the date and year description in formatted string
int GetDayOfYear(); //returns day of year 1-365
int GetYear() {return year;}
int GetMonth() {return month;}
int GetDay() {return day;}
};
#endif
//cppticket.h
//Jerry Brinegar - BrinegarQ6
//CPPTicket.h
#ifndef _CPPTICKET_H
#define _CPPTICKET_H
#include <string>
#include "Date.h"
using namespace std;
class CPPTicket
{
private:
string reservation;
int numberOfPass;
Date book, travel;
float fare;
void CalculateFare();
public:
CPPTicket();
CPPTicket(string res, int n, Date bk, Date tr);
void SetNumberOfPass(int n);
void SetDates(Date bk, Date tr);
void SetReservationName(string n);
float GetFare();
};

Can someone steer me in the right direction? |
