The 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!

Perhaps I should've taken a second glance. :smirk:

At first glance, I see three things:

  • 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

Thank you!

Thank you!
