Simplified question : Can I use the ternary operator in a new object declaration.

For example, if I have a two player game, and depending on whose turn it is:

classA { ... }

classB : classA {...}

classC : classA {...}

classA _Object = ((_turn % 2 == 0) ? new classB : new classC);

When I do this, I'm told that the operands are incompatible. I could have sworn that I've seen this working before, but I can't seem to get it to work. I tried restructuring and had the same results with this:

classA { ... }

classB : classA {...}

classC : classA {...}

classB cb;

classC cc;

classA _Object = ((_turn % 2 == 0) ? cb : cc);

Any insight would be appreciated. Thanks!

Then you can get it to work by static_cast'ing each of the operands to A*.

  Base *b = (turn % 2 == 0) ? static_cast<Base *>(new Derived1) : static_cast<Base *>(new Derived2);

Thanks for your replies.

@Phil - it wasn't my actual code, I simplified, but it was the basic idea that I couldn't get to work. The second attempt was based on something I read in another forum and didn't think would work as it was (turns out I was right).

@Alvaro - thanks for the sample code. At first I wasn't getting it to work, then realized that I wasn't static casting to a pointer of the base class.

Sometimes one needs to really stop looking at code, then come back with a fresh mind. Appreciate the help! Thanks.
