#include<conio.h>
class worker
{
    int cno;
    public:
        void putno(int);
        void getno(void);
};

{
    cno=c;
}
void worker::getno()
{
    cout<<"\n Worker Number= "<<cno;
}
class money:public worker

    public:
    int salary,exp;

        void getmoney(void);
};

    salary=s;
    exp=e;
}
void money::getmoney()

    cout<<"\n Basic Salary= "<<salary;
    cout<<"\n Expence= "<<exp;
}

    cout<<"\n Monthly Salary= "<<total;
}
void main()
{
    clrscr();
    month t;
    t.putno(1);
    t.putmoney(5000,1000);

    getch();
}

Here Is The Output :)
