    Pointers
    The closest thing C (and thus Objective-C) has to a reference type is pointers. As the name implies, pointers point to data that exists somewhere else. In order to get the thing being pointed to, you have to dereference the pointer.

    What is the difference between Objective C and C++?
    Objective-C++. Objective-C++ is a language variant accepted by the front-end to the GNU Compiler Collection and Clang, which can compile source files that use a combination of C++ and Objective-C syntax. Objective-C++ adds to C++ the extensions that Objective-C adds to C.

    How can Objective-C be implemented on top of C?
    Likewise, the language can be implemented atop extant C compilers (in GCC, first as a preprocessor, then as a module) rather than as a new compiler. This allows Objective-C to leverage the huge existing collection of C code, libraries, tools, etc. Existing C libraries can be wrapped in Objective-C wrappers to provide an OO-style interface.

    What is the difference between @interface and @interface in Objective-C/C++?
    In Objective-C, the names for classes and categories live in separate namespaces. That is, both @interface fooand @interface(foo)can exist in the same source code. In Objective-C++, you can also have a category whose name matches that of a C++ class or structure. Protocol and template specifiers use the same syntax for different purposes:

    What are class methods in Objective C?
    CHAPTER 3 The Objective-C Language There’s a tendency to do just that in definitions of class methods. Class methods are often concerned, not with the class object, but with instances of the class. For example, many class methods combine allocation and initialization of an instance, often setting up instance variable values at the same time.

    Objective-C++ is a language variant accepted by the front-end to the GNU Compiler Collection and Clang, which can compile source files that use a combination of C++ and Objective-C syntax. Objective-C++ adds to C++ the extensions that Objective-C adds to C. As nothing is done to unify the semantics behind the various language features, certain restrictions apply:
    • A C++ class cannot derive from an Objective-C class and vice versa.
