Topic: Structures and union

which one is better structure or union?(other than the space occupied )

structure is always better than union. there are to reasons
1.union occupies incorrect memory. e.g. if the lower memory space data is preceded by higher one. Then memory should be allotted is addition of these two, but the memory will be allotted will be any one out of higher and lower there is no way to assure what memory would be occupied.
2.the data given in union is not necessarily be(maybe/may not be) extracted properly but in structure correct amount of memory space will be occupied and extracting element is easy.
