Why is output -2?

Question

signed int i=10;
while(i>0)
i=i-4;
printf("%d",i);

Answer 1

Also a loop without parentheses runs the only first statement ,

Answer 2

It is easy pissy

The while condition will false when the i is less than 0 so in 3rd iteration (repeatation) i become -2 a while loop end

And prints -2
