From what I read in C++ Primer Plus this wouldn't work since ptr2,ptr3, and ptr4 are not considered pointers but ordinary int variables, the statement would have to be:
int* ptr1 = NULL, *ptr2 = NULL, *ptr3 = Null, etc...
why are you trying to create a bounding box within the method that your creating a new random object? Your object class should already be able to create a bounding box for itself using the vector location that you provide for it. If you use the code code above provided by Andy474 and pass that into your call for a 'New Object' it should have it's bounding box otherwise the question your asking is not what your looking for.
If your dead set on the c family, you may want to look at Monogame, it's based in C# and you can port that to iOS or Android with their development kits. Although, I would really look into HTML5 and Javascript as thats the upcoming mobile platforms.
