Include Standard I/O Library: #include <stdio.h> allows the program to use printf() for output and scanf() for input handling.
Variable Declaration: The int number; variable is declared to store the user-input number.
User Input: scanf("%d", &number); reads an integer from the user and stores it in the number variable.
Conditional Logic:

Positive Check: If number > 0, it is positive, and printf() displays that it is a positive number.
Negative Check: If number < 0, it is negative, and printf() outputs that it is a negative number.
Zero Check: If neither condition is met, the number is zero, and printf() confirms it.
Display Result: Based on the conditions checked, the program outputs whether the number is positive, negative, or zero.
