Info

Volatile/Mutable/const_cast S Keyword volatile means variable could be modified by hardware not known to the compiler. Key to tell compiler not to optimize it. S Cast const_cast adds or removes const <strong>and</strong> volatile modifiers S Useful when get const char* back from function, <strong>and</strong> you need to modify it. S Keyword mutable is an alternative to const_cast. S mutable member variable is always modifiable even with const member function or const object of that class. 82
const_cast< T > (v) S Adds or removes const or volatile modifiers S Single cast removes all modifiers S Result is an rvalue unless T is a reference S Types cannot be defined within const_cast const int a = 10; const int* b = &a; int* c = const_cast< int* > (b); *b = 20; //compiler error *c = 30; //OK 83
