HiLo game
 
I have students writing a simple HiLo game where they generate a random number from 1 to 100 and then some object tries to guess it. Sometimes when the guess is equal to the number and the two are compared in a while loop (while guess != number) the loop keeps going and the bject says too high or too low. How can I remedy this situation?

The random number generator [I]occasionally[/I] doesn't generate an integer even when it is supposed to (a bug listed in the official bug list). This doesn't always happen (in one class I know of, for a specific program only about 4 people out of 20 had a problem) so it can be very discouraging to debug.

The fix is to basically multipy the result from the random number generator by 1.0 before making the test - for more detail do a forum search or look at the bug list on the Alice home page.
