There are several casting operators specific to the C++ language. These operators are intended to remove some of the ambiguity and danger inherent in old style C language casts. These operators are:

• dynamic_cast Used for conversion of polymorphic types.

• static_cast Used for conversion of nonpolymorphic types.

• const_cast Used to remove the const, volatile, and __unaligned attributes.

• reinterpret_cast Used for simple reinterpretation of bits.

• safe_cast Used in C++/CLI to produce verifiable MSIL.

Use const_cast and reinterpret_cast as a last resort, since these operators present the same dangers as old style casts. However, they are still necessary in order to completely replace old style casts.
