While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

So is there no way to make it 0?

Thank you it works

But the option has be 0 when quitting

Or do I just have to deal with it lol

Cause its been annoying me

becausee I put choice != 3 so it will run as long as the vlue is not equal to 3

But when I do it as 0 it didnt work

I changed int choice = -1; to this from int choice = 0; and I made this while(choice != 0) from while(choice != 3)

So now we are pretty much there accpet it says not valid when its only meant to say that when you dont pick one of the options

Everything works fine but why is it printing not valid rather than quitting programme?

Ok I found out its because I needed to change case 3; to case 0; 😂

Always a mistake somewhere thank you

When you reopen the thread, try to use your time to improve the quality
of the question by elaborating, providing details, context, all relevant code
snippets, any errors you are getting, concrete examples and perhaps also some
screenshots. Share your attempt, explain the expected results and compare
them to the current results.

Also try to make the information easily accessible by sharing code
or assignment descriptions directly on Discord, not behind a link or
PDF-file; provide some guidance for long code snippets and ensure
the code is well formatted and has syntax highlighting. Kindly read through
