Structures - A tool for handling a group of logically related data. For example:: struct book { char bookname char authorname int no_of_pages } This is a example of structure coz it is logically related to the object books but at the same time, it has diff data types - char int. UNION:: It is juz a concept borrowed from structures. Diff between structure & union is storage. In structure, each member has its own storage location whereas all the members of a union use the same location. Union can handle only one member at a time, coz only one location is allocated for a union, var irrespective of size

Structures and unions share the following characteristics: * Their members can be objects of any type, including other structures and unions or arrays. A member can also consist of a bit field. * The only operators valid for use with entire structures and unions are the simple assignment (=) and sizeof operators. In particular, structures and unions cannot appear as operands of the equality ( == ), inequality (!=), or cast operators. The two structures or unions in the assignment must have the same members and member types. * A structure or a union can be passed by value to functions and returned by value by functions. The argument must have the same type as the function parameter. A structure or union is passed by value just like a scalar variable; that is, the entire structure or union is copied into the corresponding parameter. similarity is all three are user defined data types.
