Event Controlled Looping in C++

Hi!
For an assignment I'm trying to read a set of integers from a file and store them in an array. Instead of reading ALL of them, we are suppose the loop is suppose to stop when we reach a -1. I'm attemping to do it with this:
(ps sin is the name of my file variable)
while (1)
{
sin >> x[a];
if (x[a] = -1)
break;
a++;
}

With no luck.

Is there a better way I can create an event controlled loop where my function will stop reading from the file when it reads a -1 as the integer?

Thanks!

Yes there is (try/throw/catch) but it's overkill here. You have an obvious problem with this loop that will cause it to break early. I'd tell you what that is but that would be against the rules (http://www.linuxquestions.org/rules.php; fifth from the bottom).

Please post the declarations of sin, a, and x.
