Currency Conversion using OO

[Willing 2 Learn]

I'm trying to learn how to use C++, the OO way. I need help with a
simple program im doing to convert currency by creating a class for
this ADT. I know it should have a header file, main program,program
with functions, Constructor with arguments; default constructor with no
arguments;add, subtract, scalar multiply;show. Also I want it to show
all the #'s in cents and not round to 2 decimal places. I am struggling
to see how to use all 3 of these to convert cents to dollars and vice
versa. I already have 2 variables dollars & cents & im thinking i need
to convert both to a single variable then do the math. After this point
im stuck. Could you help me please, I would be very grateful.

2) Also, do u have any idea how to do dot product, scalar product,
magnitude, direction operations on a vector using OO?

The class should have only one datum:

long cents;

Convert as necessary, both input and output. The long might be a problem in
a real program (too small) but it is OK to use in learning the
fundamentals.

Yes.

Also, don't know the OP motivation, but have a look at the
numeric and money capabilities found in <locale>
