Explanation:

• #include <stdio.h>: Includes the standard input-output header file for input/output functions.
• int main() { ... }: The main function where the program execution starts.
• int number, i;: Declares two integer variables number and i.
• printf("Enter a positive integer: ");: Displays a message asking the user to enter a positive integer.
• scanf("%d", &number);: Reads an integer input from the user and stores it in the number variable.
• printf("Factors of %d are: ", number);: Displays a message indicating the factors of the entered number.
• for (i = 1; i <= number; ++i) { ... }: Starts a loop that iterates from 1 to the entered number.
  • if (number % i == 0) { ... }: Checks if the current value of i is a factor of number using the modulo operator %.
    • printf("%d ", i);: If i is a factor of number, it prints the value of i.
• return 0;: Indicates the successful execution of the program. The main function returns 0 to the operating system.
