    Objective C Vs C

    -   The Objective C class allows a method and a variable with the exact same name. In C++, they must be different.

    -   Objective C does not have a constructor or destructor, instead it has init and dealloc methods, which must be called explicitly.

    -   Objective C uses + and – to differentiate between factory and instance methods, C++ uses static to specify a factory method.

    -   Multiple inheritance is not allowed in Obj C, however we can use protocol to some extent.

    -   Obj C has runtime binding leading to dynamic linking.

    -   Obj C has got categories.

    -    Objective C has a work-around for method overloading, but none for operator overloading.

    -   Objective C also does not allow stack based objects. Each object must be a pointer to a block of memory.

    -   In Objective C the message overloading is faked by naming the parameters. C++ actually does the same thing but the compiler does the name mangling for us. In Objective C, we have to mangle the names manually.

    -   One of C++’s advantages and disadvantages is automatic type coercion.

    -   Another feature C++ has that is missing in Objective C is references. Because pointers can be used wherever a reference is used, there isn’t much need for references in general.

    -   Templates are another feature that C++ has that Objective C doesn’t. Templates are needed because C++ has strong typing and static binding that prevent generic classes, such as List and Array.
