Answer / m.shanmugasundaram,rjnsoftware
First of all, it is not ltti. Its RTTI
Run-time type information (RTTI) is a mechanism that allows
the type of an object to be determined during program
execution.
There are three main C++ language elements to run-time type
information:
The dynamic_cast operator. Used for conversion of
polymorphic types.
The typeid operator. Used for identifying the exact type of
an object.
The type_info class. Used to hold the type information
returned by the typeid operator.

Question In a class, there is a reference or pointer of an object of another class embedded, and the memory is either allocated or assigned to the new object created for this class. In the constructor, parameters are passed to initialize the data members and the embedded object reference to get inialized. What measures or design change should be advised for proper destruction and avioding memory leaks, getting pointers dangling for the embedded object memory allocation? Please suggest.

Answer # 1 use copy constructors 0 Shanthila There is something to be taken care in destructor, in copy constructor, suppose the memory is assigned to the embedded member object pointer with the parameter passed value, but if some other objects of different class also are pointing to this memory, then if some one deletes the object then this class member pointer object will become dangling, or if the object is not deleted properly then there will be memory leak. Please suggest the design change required to handle or avoid this situation
