This assignment is due on Monday 10/9/17 at 11:55 p.m. You can work on this assignment in pairs, in which case you must include both your names in the header of the assembly language program you submit. Both members of a pair must submit a program and answer the quiz.
Problem 1
Assignment
- Using the 231Lib.asm library, write an assembly language program that prompts the user for an integer (positive) number of seconds, which it then translates in a number of days, hours, minutes and seconds.
- Call your program hw3.asm.
- The format of your output should be similar to the format illustrated in the examples shown below.
cs231a@aurora ~/ $ ./hw3sol > 1 0 days 0 hours 0 minutes 1 seconds cs231a@aurora ~/ $ ./hw3sol > 0 0 days 0 hours 0 minutes 0 seconds cs231a@aurora ~/ $ ./hw3sol > 3601 0 days 1 hours 0 minutes 1 seconds cs231a@aurora ~/ $ ./hw3sol > 8641 0 days 2 hours 24 minutes 1 seconds cs231a@aurora ~/ $ ./hw3sol > 86401 1 days 0 hours 0 minutes 1 seconds cs231a@aurora ~/ $ 864001 864001: command not found cs231a@aurora ~/ $ ./hw3sol > 864001 10 days 0 hours 0 minutes 1 seconds cs231a@aurora ~/ $
Additional Information
- Use the DIV instruction
- Do not worry about whether words should be singular or plural. We do not know how to test quantities yet. Make your program output all the words in their plural form.
- Make your program output all the quantities on one line.
- You can use WolfranAlpha to convert seconds to day/hours/minutes/seconds, to test your program. WolframAlpha will correctly understand what to do if you enter something like "864001 seconds" in the search bar.
Submission
- Document your program well, and submit it on Moodle, in the Homework 3, Problem 1 section. Be careful as Moodle gives only 5-minute increments for the closing time, which means you have until 11:55 p.m. on Monday to submit the program.
Problem 2
- Answer the quiz on Moodle, in the Homework 3 Problem 2 section.
