    What is the use of declared properties in Objective C?
    The Objective-C declared properties feature provides a simple way to declare and implement an object’s accessor methods. Overview You typically access an object’s properties (in the sense of its attributes and relationships) through a pair of accessor (getter/setter) methods.

    How do you define a class in Objective C?
    Objective-C Class Definitions. A class definition starts with the keyword @interface followed by the interface (class) name; and the class body, enclosed by a pair of curly braces. In Objective-C, all classes are derived from the base class called NSObject. It is the superclass of all Objective-C classes.

    How are objects represented in Objective-C?
    In Objective-C, all objects are represented as pointers, and static initialization is not allowed. The simplest object is the type that id ( objc_obj *) points to, which only has an isa pointer describing its class. Other types from C, like values and structs, are unchanged because they are not part of the object system.

    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.

    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.
