- Try to run this program.
- Uh oh! Something's wrong here? Why?
- It's because when you input 0 to x, computer will say:
x is positive, which is wrong. Zero is supposedly neither positive nor negative.
- So, how can we fix this program? Can we insert another if
inside the existing if's curly braces?
- Yes, you can. Let's see how.
