What does a const cast do differently?

Question

Is there an actual difference between a const_cast and c style cast (ObjectType) ?

Answer 1

A const_cast can only add or remove const-ness (or volatile-ness, though this is much less common).

A C-style cast can do the same as any of the "new" casts, except for a dynamic_cast (and it can do a few things none of them can do, though it's not really relevant here).
