plz tell me the output of this program??

Hello frnz..
I'm a newbie here but not to programming.
I've got a small doubt with this porgram..

Code:

main()
{
int *ptr=(int*)malloc(sizeof(int));
*ptr=4;
printf("%d",(*ptr)+++*ptr++);
}

In this the output it shows is : 16

But due to operator sideeffect it should be 36..
am i right??
plz correct me if I'm wrong.


waiting for ur replies...
