Strange Result on Struct

[Roby]

My friend of mine ask me about this code and I was unable to answer it why. Here's the code:

Code: Select all

#include<stdio.h>

struct da{
int a;
short b;
}asd;

void main(){
printf("%d",sizeof(asd));
}

It supposed to be 6 bytes, didn't it? But when my friend compiled it with GCC and VC++ 6, he got 8 bytes? Why?

Thanx in advance
