Q.1)     Write a C++ program to create a class Person which contains data members as P_Name, P_City, P_Contact_Number.  Write member functions to accept and display five Persons information. Design User defined Manipulator to print P_Contact_Number. (For Contact Number set right justification, maximum width to 10 and fill remaining spaces with ‘*’)


#include<iostream.h>
#include<conio.h>
//#include<manip.h>
class person
{
                char p_name[20],p_city[10];
                long int p_c_no;
                public:
                void getdata()
                {
                                cout<<"\n enter person name\t";
                                cin>>p_name;
                                cout<<"\n enter persons city\t";
                                cin>>p_city;
                                cout<<"enter person contact no\t";
                                cin>>p_c_no;
                }


                void display()
                {
                                cout<<"\n\n*************OUTPUT******************\n";
                                cout<<"\nperson name =\t"<<p_name;
                                cout<<"\nperson city =\t"<<p_city;
                                //cout<<"\npersons contact number is\t"<<p_c_no;
                                cout.width(10);
                                cout.fill('*');
                                cout<<p_c_no;
                                //cout<<cout.setw(10)<<p_c_no;
                }
};
void main()
{
                int i;
                clrscr();
                person p[5];
                for(i=0;i<1;i++)
                {
                                p[i].getdata();
                }
                for(i=0;i<1;i++)
                {
                                p[i].display();
                }
                getch();
}
                                                                                                                                        

Q.2)     Create  two base classes Learning_Info( Roll_No, Stud_Name, Class, Percentage) and Earning_Info(No_of_hours_worked, Charges_per_hour). Derive a class Earn_Learn_info from above two classes. Write necessary member functions to accept and display Student information. Calculate total money earned by the student. (Use constructor in derived class) 

#include<iostream.h>
#include<conio.h>
class learning
{
public :
int roll_no;
char name[30],cclass[30];
float percenatge;

void getlearning()
{
cout<<"\nenter roll number\t";
cin>>roll_no;
cout<<"\nenter student name\t";
cin>>name;
cout<<"\nenter class\t";
cin>>cclass;
cout<<"\nenter percentage\t";
cin>>percenatge;
}
void putlearning()
{
cout<<"\n roll number is \t"<<roll_no;
cout<<"\n student name is \t"<<name;
cout<<"\n class is\t"<<cclass;
cout<<"\n percentage is\t"<<percenatge;
}

};
class earning
{
public :
int charge,no_of_hour;

void getearning()
{
cout<<"\nenter no of hour worked\t";
cin>>no_of_hour;
cout<<"\nenter charges\t ";
cin>>charge;
}
void putearning()
{
cout<<"\ no of hour worked\t"<<no_of_hour;
cout<<"\n charges is \t "<<charge;
}
};

class earnlearn: public learning, public earning
{
public:
float money;

earnlearn() {}
void tmoney()
{
money=no_of_hour*charge;
cout<<"\n total earing money is \t"<<money;
}

};
void main()
{
clrscr();
 earnlearn ec;


ec.getlearning();
ec.getearning();
cout<<"\n********learning detail ******\n";
ec.putlearning();
cout<<"\n********earning detail is***********\n";
ec.putearning();
ec.tmoney();
getch();
}
