Hi all.

I am quite new to C++ and object oriented programming. Although I understand the concepts well enough, one question has been bothering me. Is there a way to name an object using the contents of a variable?

An example of how I would want to use would probably help. Say I wanted to create an object called jeep1 when a user presses a key and then when the key is pressed again, I would want to create jeep2, then jeep 3, etc.

So far I have just been using:
CODE
Vehicle jeep;
to create my objects but I think that there are other ways.

Any help is apreciated.

You can accomplish this in a few different ways.
If you know the total # of jeeps in advance you can use an array.
vehicle jeep[20] ; // max 20 jeeps
if not you can use a linked list of some type or a container class.
You CANNOT name variables dynamically but there is such a thing as an associative container which holds name/value-object pairs. You could say:

prog: what do you want to name your jeep?
user: OldBlue
prog: your jeep has been created, to access it, call it by name.
user: start_jeep OldBlue
prog: OldBlue is now running

The template libraries work well but if you're learning I'd do my own linked list for the experience. You can list all jeeps, sort them by name, mileage, year and learn a lot doing the programming.
