@ Nawed Nabi Zada This is a programmer's question to programmers. We're not writers 😁. I was looking for an answer to this question myself and found it and decided to share it. In my example, variable names and function names tell everything about themselves! — KUL 5 secs ago

Please see How do I ask and answer homework questions? for asking homework questions. You should include what you have tried, example inputs, example outputs, actual outputs and why you want the example outputs. Also, include possible error messages. Also, you may want to look at this open letter to students with homework problems. — dan1st 29 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 Minimal Reproducible Example then edit your post. — itprorh66 51 secs ago

@Flimzy "but if your question generally covers…software tools commonly used by programmers...then you’re in the right place to ask your question!" stackoverflow.com/help/on-topic — tuskiomi 41 secs ago

Yes, that's also true. So you can't ask about how to bake a pie, since that's not generally realted to software tools commonly used by programmers. But you also can't ask about resource requests. — Flimzy 36 secs ago

Welcome to Stack Overflow. Please take the tour to learn how Stack Overflow works and read How to Ask on how to improve the quality of your question. Then check the help center to see what questions you can ask. Please see: Why is “Is it possible to…” a poorly worded question? (don't just change your question to "How"). — Progman 1 min ago

Well, many years ago there were no sites here except SO. Now there are many sites under the Stack Exchange brand, and topics here are not as lax because there are now other more suitable sites. This site is specifically for questions related to programming (code) and use of programmers tools (IDEs, compilers, etc.). As I said, you should take the tour and read the help center pages to learn what is appropriate to ask here now, which is not the same as used to be years ago. And also, SO is not a forum - it's a question and answer site for a specific group of topics. Tool recs are not among them. — Ken White 52 secs ago

How to ask homework question and Open letter to students with homework problems — Barmar 50 secs ago

This question is too broad and vague for Stack Overflow. It might be on-topic for Software Engineering — Barmar 42 secs ago

Wrong site for two reasons. First, it's not a programming related question. Second, it's asking for a tool recommendation, which is off-topic here. You might try Software Recommendations, but I'd suggest (like I do with every SE site) that you first read the site's help center pages to make sure your question is appropriate to ask on that site. Here's our help center link. Also, as something to ponder: If you could do what you're asking, wouldn't that make it useless for a firewall to exist in the first place? — Ken White 1 min ago

@RogerArc I'm sorry about other users that doesn't have patience with new programmers, your question was clear and it shouldn't be closed, shame on moderators. 1. Use %y instead of %Y for your strptime function to match the desired format. 2. From the package datetime, you are importing datetime, change it to from datetime import datetime, timedelta and then call var1 = timedelta(days - 30). If in doubt, just copy and paste your question again, I edited it a bit and the question is pretty clear. — rorra 30 secs ago

Welcome to Stack Overflow! Please take the tour, read what's on-topic here, How to Ask, and the question checklist, and provide a minimal reproducible example. "Implement this feature for me" is off-topic for this site. You have to make an honest attempt, and then ask a specific question about your algorithm or technique.

If an implementation bundles and statically links functions like printf, scanf, etc. then it can let programmers select from different versions of the function which are maximally suitable for their particular use cases. While it might be nice to be able to fix some C runtime bugs or quirks, having corner-case behaviors change spontaneously is often not a good thing. — supercat 17 secs ago

@monsto, thanks, pretty interesting Q/A! Although, as highlighted by the accepted answer: Nevertheless, some JavaScript programmers such as Douglas Crockford believe that neither should be used unless absolutely necessary, and evaling/using the Function constructor on untrusted data is insecure and unwise.. For example, in case of user input the app would suffer an XSS security flaw from either eval(string) or new Function(string). — Pandaiolo 35 secs ago

waitpid() is not C++ ... note that you can find it described in the Linux Programmer's Manual (as is the compiler apps c++ and gcc, and the make tool, etc.) On linux, you simply type man waitpid. Futhermore, C++ provides std::thread. If you want to learn and program in C++(or get support from C++ programmers), std::thread can probably support what you are trying to do. You say your code is C++, but waitpid() is provided by the c++ tools. — 2785528 41 secs ago

Agreed, and you have marked your post for Linux. I guess I'm suggesting you move this post to ask the talented c programmers that are not interested in C++. — 2785528 5 secs ago

@Dan: There's only one wrapper, and Section 2 is its primary documentation. The man page in 3p (again, that's 3p not 3!!!) documents how POSIX says this function is supposed to behave. Section 2 documents how it actually behaves under Linux, which may be different (though hopefully compatible). Section 3p is meant as a convenient resource for programmers trying to write code that is portable to POSIX systems other than Linux. — Nate Eldredge 37 secs ago
