Thread: Help calling a function

Alright this mite b kind of long so thx in advance if u can help me i really really appreciate this. my program was already done. its an association and containment program between pets and their owners and ive done all the stuff already except the owners birthdate.. I now have to use the schools Date class to output the owners birthdate and im havin trouble doing that. i had it working b4 using their class now icant get it. Its alot of diff files ill post what i think shows the prob and if u need more ill post it.

here is the date.cpp file i wont post the .h b/c its pretty much the same ig uess but w/ ou the definitions

Date.cpp - THIS CANT B CHANGED i didnt write this lol

Code:

#include "Date.h"
#include <iostream>
#include <cstdlib>	

// When we're not in a header file, it is ok to
// have "using namespace std"
using namespace std;
namespace CS1124{
Date::Date(string date) {
	// atoi comes
	month = atoi(date.substr(0,2).c_str());
	day = atoi(date.substr(3,2).c_str());
	year = atoi(date.substr(6,4).c_str());
}
void Date::display(std::ostream& os) const {
	os << month << '/' << day << '/' << year;
}
bool Date::earlierThan(Date d) const {
	if (year > d.year)
		return false;
	else if (year < d.year)
		return true;
	else if (month > d.month)
		return false;
	else if (month < d.month)
		return true;
	else if (day >= d.day)
		return false;
	else 
		return true;
}
int Date::getYear() const {
	return year;
}
void Date::setYear(int x) {
	year = x;
}
}

here is my owners.h - ive cut it down

Code:

 
#ifndef OWNER_H
#define OWNER_H
#include "Pet.h"
#include "Date.h"
#include <string>

namespace CS1124
{
	class Owner
	{
		public:
			//constructor initializes the name of the owner and the birthdate
			Owner(std::string ownerName, std::string date);

			
		void displayDate ();
			
		private:
			//int month, day, year;
			std::string ownerName; //owners name
			Date date; //from date class. will get the birthdate
			Pet* pet; // pointer to the pet class for a pet
	};
	//Overload << to output the information
	std::ostream& operator << (std::ostream & os,const Owner& owner);
	
}
#endif

and the cpp cut down as well

Code:

#include "Owner.h"
#include "Date.h"
using namespace std;

namespace CS1124
{
	//constructor intializes the owners name, the birthdate from the date class
	//as well as setting the owner to have no initial pet
	Owner::Owner(std::string ownerName, std::string date):
	ownerName(ownerName), date(date),	pet(NULL)
	{}

	//output the owners and pets names

	void Owner::displayDate()
	{
		date.display();
	}

	ostream& operator << (ostream & os,const Owner& owner)
	{
//--------------------------------------------
//THIS IS WHERE MY PROBLEM ISS!!!!!!!
//owner.displaydate in specific
//-----------------------------------------------
		//display the owner
		os<< "Owner: " << owner.getName() 
			<< " DOB: " <<" " << owner.displayDate();
		os << " My Pet: ";
		//Check if he has a pet
		if(owner.getPet())//display that pet
			os<<owner.getPet()->getName();
		else //if not say he doesnt
			os<<"I don't have a pet.";

		return os;
	}


}

im sorry its so long - basically i just want to display the date and i have to use the date class to get it and display... ive tried doing
date.display() in the overload << function that didnt work.
i tried now as u can c making a display func inside of owner that dislays the date but thast not working any help is appreciated.. im aslo going to attach the files incase any1 gets really bored.

BTW i coulnt upload Pet.h and pet.cpp b/c im liimted to 5 but i can in another post if any1 wants it lol i doubt it

i think i understand wat ure sayin ..but could u show me a lil im havin a hard time with this one

well i understand what u guys mean now but when i took that function and used it i get this error

this one points to date.display(os);

Code:

c:\Documents and Settings\Mine\Desktop\NEW HW03\HW03 NEW\hw03\Owner.cpp(17): error C2664: 'CS1124::Date::display' : cannot convert parameter 1 from 'std::ofstream' to 'std::ostream &'

and this one 2 <<owner.displaydate(os); of course

Code:

c:\Documents and Settings\Mine\Desktop\NEW HW03\HW03 NEW\hw03\Owner.cpp(25): error C2664: 'CS1124::Owner::displayDate' : cannot convert parameter 1 from 'std::ostream' to 'std::ofstream &'

ok ive got it working .. well almost

it displays the date for example like this
5/1/192600460778
that 00460778 i have not idea what that it but it displays it afta each date... any ideas...

ive zipped the program just rename it.

I was tryin to debug this thing this morn and when it gets to the line

Code:

Owner mm("marilyn", "05/01/1926");

thats when the junk 0490809 blah gets initialized.
I'm guessing then it could be something with the constructor of Owner when try to initiliaze date. Any clues? im so close!! lol

heres the code btw

Code:

class Owner
	{
		public:
			//constructor initializes the name of the owner and the birthdate
			Owner(std::string ownerName, std::string date);

			//getters
			//get the name of the owner
			std::string getName()const{return ownerName;}
			//get the pet if he has one
			Pet* getPet()const{return pet;}
		
			//when he buys the pet, the owner needs the name of the pet
			//change the status of the pet owner
			void buyPet(Pet& p,const std::string name);
	
			//Again change status for the pet running away
			void runaway();
			
			//ostream output for display() from date.h
			//displays the date
			
			std::ostream& displayDate (std:: ostream& os) const;
	
		private:
			//int month, day, year;
			std::string ownerName; //owners name
			Date date; //from date class. will get the birthdate
			Pet* pet; // pointer to the pet class for a pet
	};
	//Overload << to output the information
	std::ostream& operator << (std::ostream & os,const Owner& owner);

and owner.cpp

Code:

//constructor intializes the owners name, the birthdate from the date class
	//as well as setting the owner to have no initial pet
	Owner::Owner(std::string ownerName, std::string date):
	ownerName(ownerName), date(date), pet(NULL)
	{}

	std::ostream& Owner::displayDate (std::ostream& os) const
	{
		date.display(os);
		return os;
	}

	//output the owners and pets names
	ostream& operator << (ostream & os, const Owner& owner)
	{
		//display the owner
		os<< "Owner: " << owner.getName() 
				<< " DOB: " <<" "; 
		os << owner.displayDate(os);
		os << " My Pet: ";
		//Check if he has a pet
		if(owner.getPet())//display that pet
			os<<owner.getPet()->getName();
		else //if not say he doesnt
			os<<"I don't have a pet.";

		return os;
	}

i cut it down again for posting purposes.. the file stuff is in the zip in my previous post thx

thx every1 its working good now
