Class Inside a class

[mbouster]

Dear all, I would like to ask you how to initialize the following:

I want to initialize a class inside another class.
How I will be able to do so?

An example:

/*Class Date*/
class Date {
	public:
		Date(){} // default constructor
		int day;//day of the month valid till 31
		int month; //month of the year , valid till the 12
		int year;//year 
		
		/* function prototypes*/
		void setDate(int d, int m, int y);
		void printDate();
};
	/*functions*/
	void Date::setDate(int d, int m, int y){day=d;month=m;year=y;}// i must vallidate entries for days months etc
	void Date::printDate(){cout <<day<< "/" << month << "/" << year <<endl;}
/*end class Date*/

This is the class I want to include in another class implementation
I want to include this in the following class:

/*Class Flights*/
class Flights{
	public:
	Flights(){}
	string flight_code;
	string departure;
	string destination;
	FlightOperators FOperator;
	int seats; // avaliable seats based on the flight
	int meals; // available meals 
	int drinks; //available drinks in the flight
	Date departuredate; //departure date of type class Date
	Time departuretime; // departure time of type class Time
	//functions 
	void addFlights(string FC, string Dp,string Ds, int s,int dd);
	void getFlights();
	void searchFlights();
	void updateFlights();
};
void Flights::addFlights(string FC, string Dp,string Ds, int s,int dd){flight_code=FC;departure=Dp;destination=Ds;}
void Flights::getFlights(){cout<<"Get flights"<<endl;}
void Flights::searchFlights(){cout<<"Search flights"<<endl;}
void Flights::updateFlights(){cout<<"Updateflights"<<endl;}
/*end Class Flights*/

I will create a member function inside flights?
how I am going to implement this???

I also have another function to initialize 150 array objects of class flights

Flights *FL=new Flights[150];
FL[0] ....??????

Thanks

Do you want to use the object of 'Flights' inside the same class?

if, yes

Follow the following outline:

Class Flights
{
public:
Flights *FL;
.......
.......
void function() // use a non constructor function for this
{
FL=new Flights[150];
........
}
........
};

I need to use Date class and initialize it into flights class.
Is this possible or I need to implement somethig else?

[alexchen]

First use code tags.

Class Flights
{
public:
Flights *FL;
.......
.......
void function() // use a non constructor function for this
{
FL=new Flights[150];
........
}
........
};

You may also want to consider using a struct if it fits your needs. They are simple to put into a class.

You can include an object of class Date into Flights just like any other data types. Your initialization of the Flight classes are correct.

So how I am going to initialize the data class inside flights?

Flights *FL=new Flights[150];// use this to create 150 oblects of Flights
//to initialize
Flights[0].departuredate.setDate; //I will use something like this?

[chikkupa]

Your Flights class is already capable of handling the Date class

use following declaration

Flights FL[150];
Flights[0].departuredate.setDate;

or

Flights *FL=new Flights[150];
(Flights+0)->departuredate.setDate;

Many thanks
Thats clears a lot of things.
Many many thanks
Wish to all of you Happy and Prosperous New Year.
