Answer 1

There are quite a few errors in this code. Some of them:

1. You didn't include Scanner library
2. Line 9 - min and max are uninitialized, but you use them later in code
3. min = max = n is invalid. What exactly was this supposed to do?

Answer 2

while expression has to be boolean type eg
while (b>0)
