Explanation:

To check if a given number is positive, the program compares the number with 0:

  • If the number is greater than 0, it is positive.
  • If the number is equal to 0, it is neither positive nor negative.
  • If the number is less than 0, it is negative.

General Algorithm

  1. Take the input number.
  2. Compare the number:
    • If number > 0, it is positive.
    • If number == 0, it is neither positive nor negative.
    • If number < 0, it is negative.
  3. Display the result
