UNION

UNION:

                                                ======

            The Union is also the same like structure. But only one ,main different

            is it will allocate the memory in commanly for the all members.And

            it will share the memory for all members.

            Defining:-

            ==========

                                    union <tag-name>

                                    {

                                                members;

                                    };

            When ever we execute in our program at that time, the processor will

            allocate the memory equal to the highest variable size.In here the

            memory space will take very less only. But we can not be able to access the

            all members at a time.
