Your answer is only a piece of code, provided without context. To help other programmers improve, it would be better to add some explanations on what your code snippet is supposed to address and how. — Laurent Jospin 31 secs ago

You're asking for recommendations for libraries or packages, which is not the kind of question StackOverflow is for. Try softwarerecs.stackexchange.com, or post an example of code you cannot get to work with the solution you would like to use, and someone will be able to help you to get it to work. — Grismar 23 secs ago

welcome zkoza the any 11year old programmer can tell r,g,b stands for varibles being used to set int r,g,b; so i tell you this that in setpixel x,y is an pos and then colors1 stands for the color ref we made and if jr programmers want to use their own imagination and write code they should know what is c++ or any other programming language int x,y is used for pos — AlanTheGameEngine 36 secs ago

@khelwood, it would be much better to use elifs rather than rapid if usages, the code is not easy to read at the moment but it would be much better when the changes are applied, also, use indentation for you if statements, the form you are using is not common among programmers. link This link briefly explains if statements. — pouya_ghahari 16 secs ago

The website you've got this code from is not giving you high-quality C. There's several defects in their code -- sizeof(char), missing consts, needless casts, casting the value returned from malloc, use of int instead of size_t. Even the "expected ciphertext" is wrong, as the ciphertext is not unicode (it's bytes). Maybe none of things is an absolute mistake, it's just that it's not good C as is practiced by experienced C-programmers. — Paul Hankin just now

Please note, that this site is not a free code/script writing service! Rather is it a question and answer site for programmers about specific coding issues. So you are expected to do your own efforts. Please take the tour, visit the help center and learn How to Ask here! Once you have tried something on your own but failed, come back here, edit your post and provide a minimal reproducible example of your coding attempts! Thanks! — aschipfl 20 secs ago

I should address a few of your points. Before I do so, I should mention that you may have the wrong idea; I'm a pro software engineer with decades of experience, do my research, and rarely ask questions online. When I do so, it is because I truly have not been able to find the solutions myself. As part of that, I readily admit I'm not very good at doing searches. So I did not ask these questions out of lack or research or the desire for others to do my work for me, but rather because it seems like the problem is a very basic one that should have been solved a number of times in the past. — ag87 51 secs ago

@O.Jones the problem is that the crux of the question (is this fine under GDPR) is not a programming question, it is a legal one. Although I think the OP and yourself are correct in the approach, I don't think this is the right forum (programmers as audience) to provide guidance on this. — Shadow 41 secs ago

Questions that ask "where do I start?" are typically too broad and are not a good fit for this site. People have their own method for approaching the problem and because of this there cannot be a correct answer. Give a good read over Where to Start and edit your post. — gre_gor 27 secs ago

@JDB Though [unrelated to the answer] the title you linked is just wrong--read the full quote by Knuth to understand why: "Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%." wiki.c2.com/?PrematureOptimization — jfs 43 secs ago

You need to create a 2D array of pointers, each of which points to a string. Your return type probably needs to be char *** (Beware of Three-Star Programmers), and you need to allocate space for an alternative to gets() to read into. Beware of using fflush(stdin)! What you've got supports a vector (1D matrix) of strings and not a 2D matrix. — Jonathan Leffler 6 secs ago

Your post literally starts with "first rule of optimization: don't do it". Too many programmers have come to believe that any optimization is evil and, as the article I linked argues, too many senior engineers don't even understand the basic costs of various algorithms and data structures to be able to make a good judgment about how they will affect performance (either CPU cycles or memory management). — JDB 55 secs ago

MemSQL has a built-in Kafka ingestion tool, so if that's what you're running, then use that. Otherwise, asking for software recommendations is off-topic per help center — OneCricketeer 50 secs ago

When querying the data with a tool such as DbVisualizer there are non-printable characters at the beginning of the column that are rendered like □□. Those characters don't get automatically added when I add data using a normal INSERT. I've been told by our COBOL programmers that those characters are the length of the text in the column. When I read the data with JDBC into a byte array it does appear that those first characters represent the length of the remaining data. — Andy Kurtz 42 secs ago

Please review Clarification of "avoid if-else" advice on software engineering StackExchange. Apply what you learned to the code in your question. Then, if you can, contact the C++ instructor and discuss what you learned with them, that way I think you will better understand the true intent of their instruction. — jewelsea 28 secs ago
