[LCP]macro execution

[Srinath Thiruvengadam]

please consider this macro,
 
*********************************
#define sqr(x) (x*x)

void main()
{
  int i=5;
  int j;
 
  j=sqr(++i);
  printf("%d",j);
}
*********************************

it prints 49. it should execute like this      ( ++i * ++i )
now, when this goes on to stack , shouldnt it go like this
 
|7 |
|* |
|6 |
 
the result should be only 42!
 

Thanks & Regards, 
Srinath Thiruvengadam
