Comparison of casting between Objective-C and C ++

Good, so this may be a bit of an academic question. Can someone tell me if / how C ++ casting operators can translate to Objective-C ... or how / why they are not needed?

I have not seen C ++ for several years now, and it seems that every time I turn around, they add a few new keywords. I recently introduced C ++ to various casting operators reinterpret_cast, static_cast, dynamic_cast, and const_cast. I'm a little vague when situations arise that you will need to use all of these types of ghosts.

I've been using Objective-C for a year or two and feel pretty comfortable with it. (Before that, he was the main person of C). I am trying to understand why C ++ seems to have all this complexity. Or, in another way, that Objective-C is missing, that it does not (or need?) This many casting types?

See this answer to the question When to use static_cast, dynamic_castand reinterpret_cast? by value, each type of cast.
