It seems that every object is a pointer in the sample code I have
seen.  Is there any distinction between an object and its pointer?

In C++,  C* c; would be an uninitialized pointer. But the following
line will creates an object with the constructor C().

C c;

It seems that there is no such equivalent syntax in Objective-C.
objects are created either from factory pattern or  [[A alloc]
someInitMethod ....];
so, is it possible to write?

NSString a;
NSNumber b;
