Think negatively!

Look at the test that the code is doing:

while(n <= 8 && n >= 1 )

This checks that n is in the range that is valid. You want the loop to repeat if it isn't in the range. So, you need a test for the opposite.

Two ways to do that. Either negate the test :

while( !(n <= 8 && n >= 1) )    

or check for the opposite:

while(n > 8 || n < 1 )
