 Posted: Tue Jun 06, 2006 6:44 pm Post subject: simple c++ question for array |
 |
|
Hi,
I just started c++ programming. Could you please give some tips for how
to define this simple problem.
Say, I have 30 carriers from carrier number 35 to 65. Now these
carriers may be 1 bit,2 bit or 4 bits.
I can define this
b[]={1,2,4}; // b(bit loading information) is an int which can be 1,2
or 4 bits.
if c is the carrier then how do I relate this c to b. For example
carrier number 36 can be 1/2 or 4 bits.
Please help me. It might be a stupid question for you guys but beginner
like me want to learn the basics.

Unless you exclude one of the ends, it's 31 carriers. But it really
has no bearing on the problem, methinks.

I am not sure I understand the problem. Why not give each carrier
a data member that would define how many bits it carries?
Do you expect 'b' to be defined outside of the 'carrier' and possibly
change at run-time to something like {3,5,7} ? What's the relationship
between a carrier and 'b' in your model?

Why do you think you need to "relate" anything to anything? What is
it you're trying to model here?

You're starting from a wrong end. First design the interface of your
carrier, then define its implementation. What's the interface? How
is it going to be used? Apparently not enough information provided.
