“West-Const vs. East-Const”
West-Const (The common one)
int * num = new int(42); // Mutable ptr to a mutable int const int * num = new int(42); // Mutable ptr to a const int int * const num = new int(42); // Const ptr to a mutable int const int * const num = new int(42); // Const ptr to a const int
East-Const (Right to Left (RTL))
int * num = new int(42); // Mutable ptr to a mutable int int const * num = new int(42); // Mutable ptr to a const int int * const num = new int(42); // Const ptr to a mutable int int const * const num = new int(42); // Const ptr to a const int
