Can Objective C compiler ignore them ?
I dont have much of experience with C++ mixed with Objective C, I was following a box2d tutorial which has the entire engine in c++ but the example is prior to ARC.

Do I have to do something special ?

    From your comment:

    If a C++ pointer is pointing to a memory location allocated using new in the c++ code, will ARC add a retain call for it ?

    You can’t retain-release C++ objects – they’re not Objective-C objects. Regarding this, the answer to your other questions are as follows:

    What happens to C++ pointers ?

    Nothing.

    Do I have to do something special ?

    No.
