Objective C Vs C++

1. Declaration changes:Class declaration-in C++ each class is structure and variables, methods are in that structure.In Objective C variables are in one section and methods are in another section.Objective C uses + & - to differentiate between factory and instance methods,C++ uses static to specify a factory method.Method declaration varies,Objective C uses small talk approach.Method calls syntax varies,C++ uses arrow operator and objective C uses square operator.
2. In objective C same name for method and variable is allowed but in C++ it is not.
3. Objective C does not respect public and private(it knows about them but doesn't really use them) as it does in C++.
4. Objective C does not have constructor and destructor.Instead it has init and free methods,which must be called explicitly.
5. C++ uses strong typing and Objective C uses weak typing(run time binding).
6. Objective C does not allow stack based objects,C++ these are allowed.
7. Operator overloading is not supported in Objective C,C++ these are supported.
8. Templates are not allowed in Objective C,C++ these are allowed.
9. abstract objects when instantiated,Objective C generates runtime errors,C++ generates compile errors.
