C pointers vs. Objective-C pointers

Question

I\'m coming from an Objective-C background and am trying to expand my knowledge in C. One thing has me confused, however, and that\'s the difference between pointers in C and O

Answer 1

Your NSString *string is itself a pointer. Therefore, in order to point to it, you need to declare stringPointer as a pointer to a pointer. That is, declare stringPointer like this:

NSString **stringPointer;

Then everything should work. Note that the same pointer semantics apply in C and Objective-C.
