little puzzle

[czerny]

Try to guess first what is the output of this little proggi!

Code Select Expand

#define SIZE 5

int size(int s[SIZE])
{
return sizeof(s);
}

int main(int argc, char **argv)
{
int x[SIZE],k,n=SIZE;

k=size(x)+sizeof(n++);
printf("%d\n",k+n);
return 0;
}

sizeof(n++); is a cheat

Array to pointer decay caught me off guard. At least C++ has references to arrays. 
Interesting how n remains 5 after sizeof(n++). I didn't know that.
