If that's what you think, then why are you wasting your time on this course?
That is exactly what you will be expected to do as a real programmer in the real world - if that's not what you want to do, then drop this course and find something more appropriate to your intended career path...
this is something you might need to do more often that you think; companies do backward engineering all the time trying to figure out how their competitor are doing better! it goes all the way from electronics, through heavy machinery and - yes, hi-tech (and lo-tech) weapons!
Which brand or product.
