Answer / nakul sharma

Memory allocated for any structure is equal to the sum of
memory required by each structure member.

Example: In a structure 'abc' below, memory allocated will
be 7 Bytes (2 Bytes for int a + 1 Byte for char b + 4 Bytes
for float c ina 32 bit processor)
struct abc
{
int a;
char b;
float c;
}

But in union memory allocated for it is equal to the memory
required by the biggest (in terms of memory it use) union
member.

Example: In a union 'abc' below, memory allocated will be 4
Bytes as float c is the biggest union member here and it
uses 4 Bytes of memory in 32 bit processor.

union abc
{
int a;
char b;
float c;
}
