RELOAD! There are 6244 unanswered questions (90.0785% answered)
You are correct that this is not a good question for Stack Overflow and will likely be closed because of that. Additionally, code under review must be in the question itself, not only on an external site. If there is too much code, that is an indication that you are asking a question that is too broad in scope. Finally, if you want a review of all aspects of the code, and the code works as is, you might have better luck on Code Review, but I implore you to read their help center first before asking. — Heretic Monkey 11 secs ago

This week on the podcast, we sit down with Jess Lee, one of the co-founders of Dev.To, a social network where programmers come to learn, chat, and share ideas with a community of other coders. She explains her strange journey from working as a tour manager for Kidz Bop to building one of the fastest growing and most progressive online platforms for software developers.

Paul and Sara chat about what language is best to choose as your first when you’re just getting started on your journey as a programmer. Probably not Mathmatica, but it’s a neat one. …

You are missing “naïve” for instance. Also, this is an offtopic on this site, you’d better post it somewhere on codereview.stackexchange.com or like. — Aleksei Matiushkin just now

This turns into a code review but still: For a real program it is indispensable to check whether scanf("%i",&i); was successful. the scanf family of functions returns the numbers of items read successfully. In this case it must be 1, or else i will have an arbitrary value (and the program formally exposes undefined behavior, even though it will "work" on PCs, but with some unknown value for i). You should also check the input for values which seem to large or <= 0. — Peter - Reinstate Monica 31 secs ago

If the code is generally working well, you could ask to review it on Code Review. Maybe it turns out there is a better approach to solve the problem to begin with, which makes the code better readable.

@IgorRivin ThisWorkbook is indeed a class, and I never said you don't need any state. In fact nothing prevents you from adding a class module to your project and making it expose 50 public fields (that compiles down to 50 read/write properties on the class' default interface). Careful not to confuse state for data: VBA code hosted in an Excel document has the opportunity to leverage worksheets to persist data; state in code is fine, data in code isn't. I'd suggest posting your finished, working code to Code Review if you want feedback on any/all aspects of it. Cheers! — Mathieu Guindon 30 secs ago
