Classes

I have a program which includes a class circuit, when i call it im using c1.series........
I want to be able to include c2.parallel........ how do i go about including a second class statement so that i cant use the c2. caller?

rephrase that

Something like this?

Code:

class Cseries
{
   ...
};

class Cparallel
{
   ...
};

class circuit
{
   Cseries series;
   Cparallel parallel;
};

doesnt matter now, sorted it. cheers
