Hey, all I am currently doing an assignment and I am having a tough time with managing my output. What I am trying to do is that when the program ends it asks the user if they would want to try again if yes it loops back to the beginning if no it exits. So my problem here is whenever I loop back to the beginning the output gets destroyed. I am a beginner programmer, and it is just now I've tried C# (I came from C++). I think the problem is coming from my console.writeline(), I think it leaves a phantom character(? not sure) like in c++'s getline(). The following snippets are my main class and the abstract data type that I created.

}I have not implemented any data hiding for my professor told us not to do so yet. I also asked him if I should create a destructor and he just said that garbage collector should do the job for me, but my problem is when I loop I THINK I can't rely with garbage collector.
Also, what is better parse or convert.to? I find them the same but some of my peers say parse is better than convert.to because it has exception handling (but, as I have read convert.to also has that).
Thanks to those who'll be reading this and replying! Thank you so much!
