Answer / vishnu nayak
Union occupy same memory area for different members in a
union.
Same are is allocated for different data types of the
members of union
eg:
union
{
int a;
char c;
float f;
}temp;
Size of Float will be size of union.
same memory is used for char and int as well.
Advantages: Memory consumption is less.
Disadvanteges: if one of the member variable is updated the
it will be reflected in the remaining 2 variables.
