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.
