I know this is a really easy problem, but it's driving me up the wall. I"m writing a program that at a point I have to multiply something in an arry by -1 to mark that I have already been to that point, then when I finish what I am supposed to do I multiply by -1 again to change the array back to normal.
Anyways, my question is this. When I multiply by -1 which the code is squares[start] * -1, it give me the following error
'*': operator has no effect; expected operator with side-effect
