Hi guys, could someone help me with this exam?
I really need these 2 parts and i don't know how to do them.
Please, help me, please.
1)In a modularized C project, take from a file done by the student records of medical prescriptions made in this way:
#prescriptioncode#doctorsurname#exemption#issueday#issuehour
(int, char[], char[], int, int)
2)verify that there aren't more than 3 prescriptions with the same surname in the same the day, if there are this prescriptions need to be moved to another day and saved in the file "prescrizioni.txt"
3)sort the prescriptions by the relaction's order <issuedate, issuehour,="" surname="">.
The increasing or decreasing parameter is choosen by from input. Save the sorted prescriptions in the output file "Ordinamento.txt".
I'll send the full project

What I have tried:

What is the problem?

Chris Miccione 28-Jan-21 6:51am

i don't know how to do the point number 2 and 3

Richard MacCutchan 28-Jan-21 7:34am

I cannot figure out where in the code tyou are saving all the prescription data after you read it from the input file. The logical thing would be to create a struct to hold the details of each prescription, and build an array of these as you read the input. You can then count the entries that look the same, sort them into different order etc.

We are more than willing to help those that are stuck: but that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

The easiest way is to aquire the needed skills, solver the task in excellent quality and impress your teacher and mates with your knowledge. By the way: girls prefer sucessful man. ;-)

So start with learning to use the debugger with some tutorial.

tip: learn to break down issue to small and solvable task which you can implement as functions and classes. Test every pieces of code to be sure it works fine.

If I take your exam for you do I also get your diploma if/when you graduate?
