have this program i need to write for class....having alot of trouble....this is a entry level class..... here is the program guidelines....

Write an Assembly program that reads a non-negative integer (0 - 32,767) in decimal and prints its equivalent in binary after making sure it's non-negative. The output must show all 16 bits. AND YOU MUST USE A LOOP and local variables for producing and outputing the bits. For example, if input is 120, output should be:
0000000001111000.
If input is -120, output should be:
Enter a non-negative number only.

Hint: To get the remainder of a number divided by 2, AND the number with 1. So, 13 % 2 is accomplished by doing 13 AND 1.


Thank you for any input or advice

Do you have any code to show?
