don't understand this code.. - ghiboz - 11-13-2008
Hi all (especially joe :wink: )
I'm looking your new code...
example cartire.h....
what means the T datatype?
template <typename>
??
i feel hard understand this...
thanks in advance!

I guess that it means that you can use it universally.
On objectcreation you specify what type you want to use e.g.
CARTYRE <int> tire;
And then all occurrences of T will be replaced by the specified type.
Others will probably explain it better

thanks, so in some part of the code is there a definition of T used by a double for example

Here's a pretty good introduction to templates (specifically see the section on Class Templates):
http://www.cplusplus.com/doc/tutorial/templates.html
In the car.h file you'll see CARDYNAMICS <double> dynamics, which means that for all of the car classes "double" gets substituted for T. I did it this way in case I wanted to try using a 32-bit float instead of a 64-bit double.
