you will have to study through structure padding concepts.
It depends on the compiler.
struct
{
char a;
int b;
}
The above struct size will be 8 in standard compilers (Turbo
C is a non-standard compiler). bcoz between a and b there
will be 3 pad bytes placed..

Refer this link you will know everything about structure
padding..All d best :)
