look , that '-' operator being unary was a stupid thing.forget it.it was the binary '-' , i realise.
when 2 is converted to unsigned int it becomes unsigned 2 , so TOTAL_ELEMENTS-2 has a value equal to unsigned 5 , and then when d is being converted to an unsigned int it gets a large positive value and
so the loop fails.
is that happening here??
and yes, i didn't write this code,this is some c puzzle i found on the web.
thank ya all.
