{ ID = I; Rate = R; }
void Change( int New, int DT )
{ Rate+= New ; Date = DT; }
void Show( )
{ cout<< “Date:”<< Date << endl ;
cout<<< ID << “#”<< Rate << endl ;
} };
void main( )
{ Stock A,B,C,D;
A.Initialize( ) ; B.Initilalize( ) ; C.Initialize( ) ; D.Initialize( ) ;
A.RegCode(1024,150) ; B.RegCode(2015,300) ; B.Change(100,29) ;
C.Change(-20,20) ; D.Change(30,15) ; A.Show( ); B.Show( ); C.Show( ); D.Show( ) ;

6. Write the definition of a class RING in C++ with following description:
Private Members:
Rno - data member of integer type
Radius - data member of float type
Area - data member of float type
CalcArea( ) - Member function to calculate and assign Area as 3.14 * Radius*Radius.
Public Members:
GetInfo( ) - A function to allow user to enter values of Rno and Radius. Also, this
function should call CalcArea() to calculate Area.
ShowInfo( ) - A function to display Rno, Radius and Area.
 
7. Define a class BUS in C++ with following description:
Private Members
- A data member Busnumber of type integer
- A data member Destination of type string(25 characters)
- A data member Distance of type float

- A member function CALCFUEL() to calculate the value of Fuel as per the following criteria
 
Distance                                  Fuel
<=1000                                   500
more than 1000 and <=2000    1100
more than 2000                       2200
Public Members
A function FEEDINFO( ) to allow user to enter values for Bus Number, Destination,Distance & call function CALCFUEL( ) to calculate the quantity of Fuel.
A function SHOWINFO( ) to allow user to view the content of all the data members.
