CppConstCast

---

(C++) const_cast

Keyword to enable you to cast away a constness of a variable.

You should avoid casting away const, except when using a non-const-correct API [1].

Don't use C-style casts [2].

Other casts are:

• static_cast, for casting between simple data types (e.g. between int and double)
• dynamic_cast, for casting between related classes
• reinterpret_cast, for casting between unrelated data types
