Q: Hot Dog Cookout Calculator

Jims-RcHiii... Can you please check the code and see whether I might have done a mistake ? Beginner's eyes can be misleading quite easily. I feel like there's something wrong in this solution. I can't figure out what. so please check the solution and let me know. keep in mind i'm native sinhala speaker...

 
I like this and would suggest separating seach env into it's own file and then include them here, esp if you use git and code review system. Keeps things tidy. — Sgnl 11 secs ago
 
> I'll tell you what I'm doing. I want to buy eight hot dogs and eight hot dog buns to go with them. But no one sells eight hot dog buns. They only sell twelve hot dog buns. So I end up paying for four buns I don't need.
 
@SᴀᴍOnᴇᴌᴀ I like how he takes 3 packs of buns... he only needed 2 full ones
 
I've cut a hamburger patty in half and put it into a hot dog bun to use up the bun
 
12:32 AM
Yeah we're normally left with left over buns too. I think the film's being ironic here since 8 + 8 + 8 = 12 + 12

Yes, and you said you have working code that is slow, but you have working code. It is not a question about fixing code, it's a question about optimising it. Code optimisation is more on topic for Code Review. — Llama 38 secs ago

Q: Implementation of Dynamic Array with allocators and C++20

PavelDevTo train my skills in C++, I decided to implement the well-known "Dynamic array" data structure on my own. I realized early on that using pointers or smart pointers is wrong, as it leads to calling default constructor on reallocation. A naive approach for the push_back function would include: T* ...

Q: Python Library for Random Collections

The collections are tuples of 2, tuples of 3, a list, a 2d list, a set, and a dictionary. The odds are all equal in the random library. Notably, the collect...

 
Hi, your post should only contain one question, so you should probably remove the second two questions. I also second the suggestion to check out Code Review. Once your code is functional, you can post there about how to improve it — C_Z_ 21 secs ago

StackOverflow is not a Code Review site. There is a Code Review StackExchange site, but you'll have to read their rules before posting, unlike what you did here. — Random Davis 7 secs ago
 
8:55 PM
@RandomDavis If a user has not read rules when posting on SO why would you expect the user to read the rules of another site? Only suggest sites when you know the question would be a good fit - "Be familiar with the destination site". — Peilonrayz 15 mins ago
@Peilonrayz I did not say this question would be a good fit there. I implied that they might be able to get help at that site, but that they'd have to read the rules regardless, and follow them, unlike what they did here. I specifically said that they should read the rules, so I'm not sure what else I could say. I purposefully didn't link the site because, again, I'm not saying or implying that they should re-post this question there. — Random Davis 3 mins ago

I have not even used continue Your code works then maybe go to codereview ? If I had wrote what you did my IF would have flags and then I would build an pscustomobject with the flags and not have the continuedcaz 55 secs ago
Glad to hear you're not alone, hopefully you all can fix it. Also, I know this isn't Code Review and I'm no complete expert yet either. But I thought I would suggest a few things as you mentioned you're a first time programmer. Your Program.cs file is pretty cumbersome, consider refactoring your code and splitting up your methods into easier to manage classes. Also, I noticed you have some repetitive code, for example in your ReadItems(), ReadSales() and SaveItems(), SaveSales() methods. — The2Step 27 secs ago
@dcaz that link seems to just explain 'continue', there are more legit uses for it but it works in this example just fine and is being used correctly. Is there a site for code review I can use ? — Mike Q 56 secs ago
