istream& inputStream Overload

[jnneson]

Hello,
Please I want to get an input of string, like mm/dd/yyyy hh/mm/ss
where first mm is month,.... and second mm is minutes....
then want to split each into date object.. like ... month day year.... after each / ....
I am lost here...
thanks

istream &operator>>(istream& inputStream, Date& dateObject)
{
    string inVariable[20];
    inputStream.getline(inVariable, 20, "\n" );
    //inputStream >> inVariable;

}

How is your Date class defined?

[jnneson]

Following an interface of

class Date;

ostream &operator<<(ostream&, const Date&);
istream &operator>>(istream&, Date&);

class Date {

  private:
    int month;
    int day;
    int year;
    int hour;
    int minute;
    int second;

  public:

    Date(void);
    Date (int month, int day, int year, int hour, int minute, int second);

    virtual void setMonth(int&);
    virtual void setDay(int&);
    virtual void setYear(int&);
    virtual void setHour(int&);
    virtual void setMinute(int&);
    virtual void setSecond(int&);

    virtual int getMonth(void) const;
    virtual int getDay(void) const;
    virtual int getYear(void) const;
    virtual int getHour(void) const;
    virtual int getMinute(void) const;
    virtual int getSecond(void) const;

    virtual bool operator== (const Date &rhs);
    virtual bool operator< (const Date &rhs);

//    friend ostream &operator<<(ostream&, const Date&);
//    friend istream &operator>>(istream&, Date&);

};

#endif

Then I implement the below code...

/** Class Date models a date and time.
//This class contains private data members to store the day, month, and year of a date
//and the hour, minute, and second of a time.
//The class declaration includes the following public members

**/
#include <iostream>
#include <cstdlib>
#include <cctype>
#include <sstream>

#include "Date.h"

using namespace std;

{
    month(0), day(0), year(0), hour(0), minute(0), second(0);
    /**Default constructor, all variable are set to Zero..  **/
};

Date::Date(int theMonth, int theDay, int theYear, int theHour, int theMinute, int theSeconds)
{
    if(theHour < 0 || theHour > 24 || theMinute < 0 || theMinute > 59 || theSeconds < 0 || theSeconds >59
        || theDay < 1|| theDay >31 || theMonth <1 || theMonth > 12 )
    {
        cout << "Illegal argument to Date Class constructor.";
        exit(1);
    }
    else
    {
        month   = theMonth;
        day     = theDay;
        year    = theYear;
        hour    = theHour;
        minute  = theMinute;
        second  = theSeconds;
    }
    if(theHour == 24)
    {
        theHour = 0; //Standardize midnight Time as 0:00
    }
}

    if(newMonthValue <1 || newMonthValue >12)
    {
        cout << "Illegal argument to Date Class constructor.";

    }
    else{
        if(newHour == 24)
            hour = 0;
        hour = newHour;
    }
}

void Date::setMinute(int& newMinutes)
{
    if(newMinutes <0 || newMinutes> 59)
    {
        cout << "Illegal argument to Date Class constructor.";
        exit(1);

I am lost with the overloading of >> and << , Since the TestDrive.cpp, is not compling
please help pointer out my error..
Thanks
