What's going on

This program demonstrates basic conditional logic using if-elif-else.

Key Concepts:

Use > to check if number is greater than 0 (positive)
Use < to check if number is less than 0 (negative)
Use else for the case when number equals 0

Logic Flow:

1.Check if num > 0 → Print "Positive"
2.Else if num < 0 → Print "Negative"
3.Else (num == 0) → Print "Zero"
