Hi there,

I am trying to write using Objective-C++. I have read the docs and 
understand what I can and can't do with it but I have a really basic 
problem. When I put #include <iostream> in my header files I get an 
error saying that the file cannot be found? Why is this?

Also when creating the file, do I create a C++ file or an Obj-C file 
or doesn't it matter?

Finally, I want to do some thing like this

#ifdef _MAC_OS_X
   //do some obj-c code
#endif

#ifdef _WIN32
   //use WIN32 API coding
#endif

Does anyone know how to do this? Is the above correct?

Many thanks for your help.

Phil.
