Answer Posted / shashidhar
array can contain single data type
Structure is collection of different data types
Unions can also contain different data types, but here the
different date types share the same memory within the
computers memory
ex:
==========================
|| ||
==========================
in the above the memory between || || is shared by int,
float, double declarations in a UNION.
where as in struture || || || the memory
declared for int and float and double are different.
which implies memory utilization is better in union.
When you come to pointers, well it can point to a data type
(like int) can point to a structure (struct xyz{ };) , it
can point to a union (union item { }; ) so its like a honey
BEE it can sit on anything
