A nice tutorial is at: http://www.zentut.com/c-tutorial/c-linked-list/ From a programming perspective, normally your LinkedList class would have some methods to do the things you asked about, for example: Add – create a new entry at the end of the linked list InsertAfter(Node *n) – create a new entry after indicated node in the listed list Remove(Node … Read more
Optimization comes usually comes in steps. You start off with the obvious solution. iterate_fibs_mod10; remove_odds(n); Then you realize that you really only need the expensive modulus once for one element. nth_fib(remove_odds(n))%10; Then you realize you don’t need to remove the nodes if you can deterministically find which one would have remained. nth_fib(as_if_remove_odds(n))%10; Then you figure … Read more
You have a number of not just quite right beginning to each of your functions. Firstly, let’s think about the returns for each. myStrlen should return size_t instead of int. C++ designates a size_type for counters, measuring, etc.. The remaining functions should return char* (or nullptr on failure). Looking at your myStrlen function where you … Read more
Presumably, you are looking for GROUP BY: SELECT id_rt, COUNT(*) FROM krt GROUP BY id_rt; solved how to count multiple row (separately)
It’s because you are using sc.nextInt() to get input from the user and it doesn’t consume the line so when you use switcher = sc.nextLine(); it still reads the number that the user entered before. You can add this after catcher = sc.nextInt(); to consume the line: if (sc.hasNextLine()){ sc.nextLine(); } Or alternatively you could … Read more
That’s a fairly nasty bit of corruption you’ve got in your file; it looks like CDATA is malformed in several different ways. This catches all of the errors you’ve described: <tag>.*?\K((?:<!|!<)CDATA\[.*?\]+>+)(?=.*<\/tag>) This regex checks that the string starts with <tag>, gets text up to the “start” of your CDATA tag, and then uses \K to … Read more

string adPicturesPath = ConfigurationManager.AppSettings[“AdPicturesPath”]; List<string> files = new List<string> { “235253325_23522.jpg” }; var allFiles = files.SelectMany(fn => Directory.EnumerateFiles(adPicturesPath, fn, System.IO.SearchOption.AllDirectories)); long allFileSizeBytes = allFiles.Sum(fn => new FileInfo(fn).Length); 1 solved Searching folders and subfolders for a file and get its size depending on the name
CSVReader headerReader = new CSVReader(new FileReader(this.getClass().getResource(filePath).getPath()), delimiter); solved CSVReader headerReader = new CSVReader(new FileReader(this.getClass().getResource(filePath).getPath()), delimiter);
Try this, will it work for you? https://jsfiddle.net/gwxhz3pe/6/ var width; $(‘#content’).click(function(){ if($(this).hasClass(‘open’)){ $(this).removeClass(‘open’); width = “10px”; } else { $(this).addClass(‘open’); width = “300px”; } $(this).animate({ width: width }, 200, function() { }); }); 2 solved Create a sliding div on click [closed]
change RegistryInterface.doDeleteStudent(studentID); // Static error here. with this.doDeleteStudent(studentID); Hope helped you! solved Non-static methods cannot be referenced from a static context from within the same class [duplicate]
It depends what is your purpose: implementing Agile just because it is the newest ‘fashion’ might prove to be very costly for your existing business. In my experience (almost 15 years, now) it is better to implement Agile all around the company, not only at Tech level (or DevOps as they are now calling it). … Read more
You really should learn to use the console in your browser. I just played it for a little bit with the console open, and got an error: Uncaught ReferenceError: reppS is not defined In your computePwr function, you have a variable named repS, but one time you typed it as reppS. repS = reppS + … Read more
Just change to line if (List == NULL || List->data < d) to if (List == NULL || List->data > d) And change the line while ((ptr->next != NULL) && (ptr->next->data>d)){ to while ((ptr->next != NULL) && (ptr->next->data<d)){ And you have not added 0 check.Please add that, rest is fine. For this modify the for … Read more
You’re using $this in a static function. This is why you got the error. Remove the “static” in front of “insert()” and then call $insert->insert(); solved using $this when not in object’s context error [duplicate]
