Treehouse TeacherThe line of code that increments the variable i
, i += 1;
, needs to be placed inside of the while
loop, otherwise the variable i
will never be incremented which results in an infinite loop (i.e. it never ends).
This is what your while loop should look like:
while(i < count)
{
i += 1;
Console.WriteLine("Yay!");
}
That'll resolve the error that you're currently receiving. Then you'll need to sort out the conditional expression that you're using to check if the user has entered a negative number.
Good luck!

- zero is a valid entry and should be allowed
- negative numbers should not be allowed
- the message given for a negative number should be different from the one given for parse errors
