| 4 An lvalue of type T1 can be explicitly converted to an lvalue of type |
| T2 using the cast const_cast<T2&> (where T1 and T2 are object types) |
| if a pointer to T1 can be explicitly converted to the type pointer to |
| T2 using a const_cast. The result of a reference const_cast refers to |
| the original object. |
