Answer / navin

Structure: Initially (in C) a structure was used to bundle
different type of data types together to perform a
particular functionality. But C++ extended the structure to
contain functions also. The major difference is that all
declarations inside a structure are by default public.
Class: Class is a successor of Structure. By default all
the members inside the class are private.

16 Answers   Lason,

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.
