difference between structure and union.
Answers were Sorted based on User's Feedback
Regarding the struct, each item in the struct is allocated
in a separated memory. And the size of a struct object is
total size of all its items.
But with the union, all its items are in the same memory.
And the size of an union object is size of its item which
has largest size.

Answer / siva sankari
struct employee
{
int a[20];// for tis size 20 was allocated in memory
char text;// for tis only 1byte of memory space is allocated
}
so totally 21 in size was allocated in memory space
union employee
{
int a[20];// for tis size 20 was allocated in memory
char text;// for tis only 1byte of memory space is allocated
}
but in union it takes only the maximum memory space so for each 20space totally 40 size was allocated in memory space
