Not here to do a code review - soz, not soz. Noted on KeyListener - removed. Admittedly I didn't test my solution but there's enough of a clue to make it work :) I've now tested the solution based on your feedback and updated my solutioin (which works for me). Considering this looks more like an introductory assignment I'm not too worried about throwing a correct exception back up the call-stack and having it handled correctly. Also SO doesn't reward for such comments so I keep my answers minimal. — Rob Evans 39 secs ago

codereview.stackexchange.com might be more suitable if you desire a breakdown of your code although it's still asking a bit much to have someone go through it "line by line" — Iain Shelvington 7 secs ago

Code Review is the right place, but just as note, you can get rid of the join by just using one string with all the fields and newlines in between. It is probably not much faster. If you care about run-time, you should do some profiling. — Jan Christoph Terasa 16 secs ago

This question appears to be off-topic because it is a code review request. This might be better suited to the Code Review Stack Exchange site. Before posting there be sure to read their FAQ to ensure that your question meets their guidelines. — John Conde 7 secs ago

@mediocrevegetable1, as for showing your code, you may want to ask your own question on Code Review, including the two macros in my answer that you've used to make your custom operator. Then, if you put a link to that question as a comment here, I can try to answer you. — Davide Cannizzo 55 secs ago
@DavideCannizzo Actually, just a litttle while ago I macro-ified John P's answer and that seemed to work for the same operator. Unfortunately, I don't think I have any more time today, but when I do, I'm gonna compare both macros to see where exactly the difference lies before I post a question on Code review. — mediocrevegetable1 27 secs ago

Please visit the help center, take the tour to see what and How to Ask. Do some research, search for related topics on SO; if you get stuck, post a minimal reproducible example of your attempt, noting input and expected output using the [<>] snippet editor. In this case the question MAY be a better fit at codereview — mplungjan 43 secs ago

Q: How to reduce the overhead and processing power required for this FIFO for a 2D array in ANSI C?

ChrisD91I have a 2D array of fixed size and I've implemented a FIFO function. So, the array will always be full before it reaches the FIFO function, then the FIFO will remove the oldest array, move all of the arrays up by one and then add the newest array to the other end. Basically a queue. Now, this co...

This is a question for Code Review, not Stack Overflow. Best practices are necessarily a personal or project or organizational preference. There is no one right answer here, and this could ignite a religious war. — jmarkmurphy 20 secs ago

@Peilonrayz cool- that redesign was rolled out recently to CR :) while it may be a bit of an adjustment I hope it is for the better
Oh wow that does look just a little different ;) NGL I like being able to see everything without having to click around so much.

They made the Tools button more visible.
I guess that's nice.

I know there might not be many users familiar with PHP and fewer with Yii here, but does anybody have any suggestions on how I could improve this answer?
@SᴀᴍOnᴇᴌᴀ You could add a bit about what's actually wrong with doing it like this and the benefits of your approach. Lay it on thick.
Talking about the first half.
I have no opinion on the second half.
Q: How to make this algorithm written in ANSI C more efficient?

ChrisD91Previous question with background here I would like advice on improving a FIFO algorithm for a 2D array that I've developed in ANSI C. I have written code that uses this algorithm for test purposes. Random numbers are put into an array until all elements are full. The program then asks the user w...

FYI the question isn't necessarily off-topic here (although arguably a bit broader than typical), but with a title like "Forcing uppercase in modified cells", this would make a very fine, well-received post on Code Review, where the "questions" are specifically asking for feedback on any/all aspects of the code that's put up for peer review. — Mathieu Guindon 23 secs ago
@SᴀᴍOnᴇᴌᴀ I agree with @Mast. But I don't think your answer is 'bad', your answer is good. Just one of the downsides of being a zombie hunter

@Mast Do you think it improves my post or is it still a poop?
8:59 PM
See comment.
How about a title like this:

class showing a format similar to var_dump - Some methods of this library require some improvements (see description)
"Some methods of this library require some improvements (see description)" is explicitly what we don't want to see in a title.
mmm this: class showing a format similar to var_dump
Most code on Code Review requires improvements. It's redundant to state that in the title.
is a short description of what the class does.
9:01 PM
@FranciscoNúñez Much better.
i have done the update
Q: Class showing a format similar to var_dump

Francisco NúñezSome methods of this library require some improvements (see this description): In the constructor I am trying to create the possibility that the user modifies the colors of the output. I think it can improve but I do not know if there is any standard or good practices in this regard, or if there...

I know :-)
@mast can i add some picture of output of the class???
@SᴀᴍOnᴇᴌᴀ ^ Should be better now.
@FranciscoNúñez A picture?
Why would you add a picture?
@Mast so users have a visual idea of what the class is currently doing.
9:06 PM
Would it be a picture of code or a terminal output?
@Mast the current output on browser is highlited like code ....
this is a example of output in browser...
i have a couple of themes see this:
it's like the parsed and comment-enriched version of var_dump; It even allows you to copy and paste as if it were code ...
You could add a picture. Ordinarily I'd think adding it as raw text in a code quote would be better, but I'm not sure you'd get the formatting right.
@Mast it will never get the correct format; because code appears but it is actually an output in the browser, using the highlight_string of php
