Aiesha if you need a clue its find a code equivalent for the operation of proving prime.

Eg, (sorry again a little rusty code but here goes) when 'n' not 0; "prime" if 'n' divides by 1 and n only. Perhaps another line or 2 to cover all primes technically but that the point is, is a very accurate way to code a prime programme where 'In Alumni' it is very much a taboo area to be so confident as to technically be able to 100% get correct prime programme where there are many real logical arguments to say most common ways to code are evidently incorrect.

Other areas which are unique and fascinating by fact in HE / Honorary study Aisha is the area of Dentistry and Optology where it is still decided by institute not award what exactly the level of Profession is with regards to medicine. IE, you may be an Dental Surgeon with a very low salary indeed or an Optologist (eye expert) without any sort of medical education.

I mention this as it seems that you will not be a student forever on here wheras as a tutor I am and will be answering questions about Prime number programme or advanced calculus in my opinion limitlessly and it is important that you are referred to directions which will evidently be important for your level of education desired and professional employability in the long term. All the best, M Cover SE and Cambs.
