OOPS means Object Oriented Programming Languages and
Systems and is different from the Structural programming in
the fact that in OOPS programming you take advantage of
Polymorphism, Multiple inheritance and Abstraction and
Encapsulation of the data by using Private and this helps
in Security of Data while giving you the levarage to
program your software system with the maximum flexibility.

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
