It's not clear what you're asking, because much of what you wrote doesn't make sense. Sockets require a listening endpoint, often called the "server", and a connecting endpoint, often called the "client". Any endpoint can act as either server, client, or both, according to its need. Multiple connections can be made at either endpoint. You should start with the documentation, as well as tangentsoft.net/wskfaq. The latter is targeted primarily at Winsock programmers, but much of the content applies to any socket API on any platform. — Peter Duniho 56 secs ago

@byxor Just for fun. I find it interesting to try to determine the simplest subset of a language instruction set that allows for solving any problem. As most programmers seem to think programming is basically combining loops, variable mutations, and testing conditions, I wonder if we can get rid of loops and variable mutations. I know for sure that it is possible, but my question is whether it is possible in Java. rather than answers such as "yes" or "no", which are 99% of the answers I usually receive when I ask this question, I am looking for the simplest counterexamples. — Pierre-Yves Saumont 25 secs ago

Your question may be better suited to the Software Engineering Stack Exchange site. Be sure to check what's considered "on topic", and note the part that states "Some questions, even if they appear to fit into one of the above categories, may still be off-topic" which lists "Questions asking 'What is the best way' without providing any criteria for evaluating what is best." — John 30 secs ago

Yes, just as the factory pattern itself sort of violates SOLID principles if implemented as it's meant to be. See softwareengineering.stackexchange.com/questions/302780/… — Martin Frøhlich 6 secs ago

@Teemu do you know a system where I can do UI and Graphics as easily? Then HTML/JS is the screwdriver. And we are programmers, our tools should do what we want them to do. Not vice versa. — Sens just now

Indeed, but we need to pick the right tools. There are a lot of good local server systems, maybe you should check softwarerecs.stackexchange.com . Ex. I've installed Bitnami WAPP-stack (runs PHP and PostgreSQL in Apache) for several years ago (for Windows), without much knowing about servers at that time. It has served well for all these years, and is not a pain to install. — Teemu 56 secs ago

utility recomendations maybe...I am writing a code and I need the structure of the tree that my code is building. I can generate the output I shown on my question and a some more forms. But I have non skills in image manipulations. By the way I found a very similar discussione here but I can't use Phyton language if I am off topic, never mind.

I raise your G-WAN to socket programming! There is where real programmers set apart from the rest. It's doable but you have to be not only good in C but as a programmer in general. — m4l490n 57 secs ago

@Giannis, yes and no, and it brings up another host of problems on its own. First the "%s" conversion specifier will stop reading when it encounters the first whitespace. Second, unless you provide the field-width modifier, it provides no check on the number of characters read (similar to the issue with gets). So if your buffer is 256-chars, you must provide a maximum field-width of "%255s" to limit what scanf will read to what fits in your buffer. Lastly, scanf is full of pitfalls for new programmers due to what remains in stdin after a matching-failure. — David C. Rankin 54 secs ago
