Help with instance of one class in another
 

Hello everyone.

I need help using an instance of a class in another. Below are two header files. NumDays.h and TimeOff.h

I need to have instances of the NumDays class in the TimeOff class as members. When i try to create the instance called maxSickDays, i do not get access to the NumDays member functions. What is wrong with my code? Thanks in advance.

NumDays.h

#ifndef NUMDAYS

#define NUMDAYS

#include <iostream>



class NumDays

{



private:

        int hours;

        float days;

        float calcDays();



public:

        NumDays()

        { hours = 0; days = 0.0; }



        void setHours(int hrs)

        { hours = hrs; }

        int getHours()

        { return hours; }

        float getDays();

        

        NumDays operator + ( const NumDays& );

        NumDays operator - ( const NumDays& );

        NumDays operator --();

        NumDays operator ++();

        NumDays operator ++ ( int );

        NumDays operator -- ( int );



};



#endif

and now TimeOff.H

#ifndef TIMEOFF

#define TIMEOFF

#include <iostream>

#include "NumDays.h"

#include <string>

using namespace std;



class TimeOff

{

private:

        string name;

        int idNum;

        NumDays maxSickDays;

                

public:

        TimeOff();

        



        void setName ( string n )

        { name = n; }

        void setIdNum ( int id )

        { idNum = id; }



        string getName()

        { return name; }

        int getIdNum()

        { return idNum; }

        

};



#endif

Thank you!

Can I see the part where you try to access the NumDays()?

Oops. I took all the calls to that when it would not work. Below is TimeOff.h where i am trying to use the maxSickDays instance and then its setHours member function. Thank you.

#ifndef TIMEOFF

#define TIMEOFF

#include <iostream>

#include "NumDays.h"

#include <string>

using namespace std;



class TimeOff

{

private:

        string name;

        int idNum;

        NumDays maxSickDays;

                

public:

        TimeOff();

        



        void setName ( string n )

        { name = n; }

        void setIdNum ( int id )

        { idNum = id; }



        void setMaxSickDays( int h )

        { maxSickDays.setHours(h); }    /// trying to access this instance of NumDays





        string getName()

        { return name; }

        int getIdNum()

        { return idNum; }



        

        

};



#endif

Re: Help with instance of one class in another
 

I figured out my problem. When i defined the mutator and accessor functions in the cpp file instead of the header i was able to access the nested class' member variables and functions. Below are my revised header and cpp files.

TimeOff.h

#ifndef TIMEOFF

#define TIMEOFF

#include <iostream>

#include "NumDays.h"

#include <string>

using namespace std;



class TimeOff

{

private:

        string name;

        int idNum;

        NumDays maxSickDays;

        

                

public:

        TimeOff();

        



        void setName ( string n )

        { name = n; }

        void setIdNum ( int id )

        { idNum = id; }

        void setMaxSickDays( int );







        float getMaxSickDays();

        string getName()

        { return name; }

        int getIdNum()

        { return idNum; }





        

};



#endif

now TimeOff.cpp

#include "TimeOff.h"

#include "NumDays.h"

#include <iostream>

#include <string>

using namespace std;



TimeOff::TimeOff()

{

        name = "";

        idNum = 0;

        maxSickDays.setHours(0);

//        sickTaken.setHours(0);

//        maxVacation.setHours(0);

//        vacTaken.setHours(0);

//        maxUnpaid.setHours(0);

//        unpaidTaken.setHours(0);

}

void TimeOff::setMaxSickDays ( int hrs )

{

        maxSickDays.setHours(hrs);

        

}

float TimeOff::getMaxSickDays()

{

        return maxSickDays.getDays();

}
