I'm a student. I'm trying to make an app/C++ program that can acknowledge a user and when a 2nd person uses the same identity, it should deny.
Like as an organizer of events, someone filled out a Google form to attend my event after paying  (and adding a screenshot of) payment. He should now get a unique QR code 
 (an organizer should get its copy). At the time of entry (in the event), the participant just scans the QR code and enters the event (his name cuts out from the list). Another one with the same QR (if the participant has shared the QR with his friend) should not able to attend.

It'll create a revolution in the field of booking online tickets. Will remove fakeness. I'll be thankful to you if you design such an app/program although it is not difficult at all.


What I have tried:

I've tried to make it. I think arrays will be used.

You're not creating a revolution with this. You're actually way behind what's actually in production use today.

And if it's "not difficult at all", why are you YOU not designing and writing this?

This smells a lot like a homework assignment. If you're trying to get someone to do your work for you, you're making a HUGE mistake and will only end up failing the class.

I wrote "easy" because I discussed it with my teacher and he said that but I couldn't get his point at all.
It is not at all my project. The real thing is that I'm going to organize an event at my university and I want to use (even after making) a fool-proof online ticket-booking system on my own. This is just because I asked this question. This is not my assignment, not my homework at all. Even I'm a student of Mechanical Engineering.

So, when is this event?

This still reeks of homework.

at the end of the semester. most probably

...whenever that is...

While we are more than willing to help those that are stuck, 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.

If you are having problems getting started at all, then this may help: How to Write Code to Solve a Problem, A Beginner's Guide[^]

I'm a Mechanical Engineering student studying Fundamentals of Programming as an optional subject. So if you may guide me, I'll be thankful to u.

"Guide you"? You haven't done anything that we are aware of, or if you have we have no idea what.
Muhammad Hamza Dec2022 29-Dec-22 13:32pm    
I wrote "easy" because I discussed it with my teacher and he said that but I couldn't get his point at all. If u can explain, you're more than welcome. Otherwise, plz don't waste mine and your time.

Translation: "It's my homework and I don't want to do it". :sigh:

Well, this site is not here to design your application for you. and although you seem to think this would not be difficult, I think you need to learn more about how such applications actually work. And finally, I think the world has many such applications already.

Please share just one or two. I've searched and didn't get a single one.

You need to do one of two things:
1. Do some serious research into the different elements that you will need to create such an application. Note, that it is likely to include Web pages, database, QR code reading (where?) ...
2. Forget this and find a project that is within your current skill set.
