Windows platform, console application. I've been through a class, but it's making a mistake, as far as I'm concerned, refilling the line. I'm still swimming. Please help me as detailed as possible.

Example of my decision:

filesystem::path my_path(path);
 if (filesystem::exists(my_path) && filesystem::is_directory(my_path)) {
   if (is_correct_extension(ext)) {
      for (filesystem::recursive_directory_iterator i(path), end; i != end; i++) {
         if (!filesystem::is_directory(i->path()) && i->path().extension() == ext) {
                       fout << i->path() << "\n";
                   }
               }
           }

He's making a mistake about the exception.

If I don't confuse anything, file system: the path on the list will return, among other things, the kataloges and ".." Add these values
UPD: And steak refilling because of endless recurrence.

Friend, your doubt was not very precise about your problem.However, taking into account your last paragraph, the error contained where you want to import the file to the program is as follows:Has two statements of equal variables file_ent. One being a vector float and another being FILE *.The function fscanf receives as 1st argument the potter FILE* and the rest of the parameters are equal to scanf.If you want to check if the FILE* already reached the end of the file should be checked with EOF (which means End-of-file), I also suggest using the function feof() - set in the header <stdio.h>.Other than that, other errors that will appear will be due to previous errors. For example, you probably want to give one scanf in the file and store it in the vector float, in this way you must indicate which índice do vetor you want to go through referência for function fscanf.In addition, your vector float file_ent is created with size 1, considering the startup you made and by not containing numbers in the brackets. If you know what the size of the vector is necessary for this task, put it in the brackets, otherwise you will have to manipulate it as ponteiro and use tools alocação dinâmica.

Use ID instead. Set<>♪ This will expedite the ID verificationIf it's not enough, you'll have a problem. Build a pool of several streams (but not more than a processor kernel) and let every flow search for files in one folderThe number of kernels in the system can be found by calling the functionRuntime.getRuntime().availableProcessors();

Mistake in these lines:rename("Schoolboy.txt", "Schoolboyold.txt"); remove("Schoolboy.txt"); rename("Schoolboycopy.txt", "Schoolboy.txt"); remove("Schoolboy.txt"); First you rename the file. SchoolboyAnd then you try to remove the file with the same name, and then rename it. Schoolboycopy And then you deactivate that file.If I understand you correctly, you need to Schoolboycopy Changed to SchoolboyAnd after the copy, it's gone.Then this is an example:remove("Schoolboy.txt"); rename("Schoolboycopy.txt", "Schoolboy.txt"); First, we take out the old version, and the new copy we're renamed. Schoolboy

The point is, there's a need to indicate ROI on the exit.And the size of ROI shall be the same in all three images. If, however, the image of size other than the area where it is to be inserted is to be cut off, the pre-cuted image shall lead to this dimension ( http://docs.opencv.org/master/da/d54/group__imgproc__transform.html )That's how it works.//открытие изображений IplImage* image = cvLoadImage(filename, 1); IplImage* temple = cvLoadImage(filename2, 1); //создание окон cvNamedWindow("origianl", CV_WINDOW_AUTOSIZE); cvNamedWindow("template", CV_WINDOW_AUTOSIZE); cvNamedWindow("res", CV_WINDOW_AUTOSIZE); //копирование IplImage* dst1 = cvCloneImage(image); const int widthROI = 200; //<------измененная строчка const int heightROI = 200; //<------измененная строчка cvSetImageROI(image, cvRect(0, 0, widthROI, heightROI)); cvSetImageROI(temple, cvRect(100, 100, widthROI, heightROI)); cvSetImageROI(dst1, cvRect(0, 0, widthROI, heightROI)); //<------измененная строчка //сумма cvAddWeighted(image, 0.5, temple, 0.5, 0.5, dst1); //сброс областей cvResetImageROI(temple); cvResetImageROI(image); cvResetImageROI(dst1); //<------измененная строчка //вывод cvShowImage("origianl", image); cvShowImage("template", temple); cvShowImage("res", dst1); cvWaitKey(0);

Best option is just to encrypt the Linux partition, e.g. with LUKS. That way the Windows 7 partition can't actually access any of the data on the other partition. Technically it can still read and write to the partition (there's no way to prevent this) but the data it sees is all encrypted.

You obviously need a database, but if you want it that way,$dir = 'users'; $files = scandir($dir); // получаем список всех файлов $maxId = 0; foreach ($files as $file) { $id = (int)$file; if ($id === 0) { // отсеиваем те файлы, которые не начинаются с числа (а это, как минимум, '..' и '.' continue; } else if ($maxId < $id) { $maxId = $Id; // записываем максимальный айдишник } } $filename = $dir.DIRECTORY_SEPARATOR.($maxId + 1).'.php'; // формируем имя файла, прибавляя к максимальному айди 1 $fileHandle = fopen($filename, 'w'); There's actually a smarter approach, but I have to run now.

Problem.The problem of your function obtener_longitud_array is that you lose the size information by passing the parameter array_enteros (unless you can only calculate the size of integer arrangements).Explanation.C++ is a language (translation and highlighting mine):4.2 Settlement-to-point conversionA value of the right or left side you type “arrangement of N T” or “unknown extension range of T” can be converted to a pure value of the right side of type “pointer to T”. The result is a pointer to the first element of the arrangement.Arrangement of N T It would be:T arreglo[N]; Where T It would be any guy. N any value.Arrangement of unknown extension T It would be:T arreglo[] = { ... } Where T It would be any kind, and it's the kind of arrangement you're using in your example.Passing the settlement array_enteros to function obtener_longitud_arraythe arrangement passes through the conversion mentioned ( and loses its original type. The original type of arrangement contains the size.Size as part of the guy.A settlement N T or an unknown extension arrangement T contain the size as part of its type:/* Tipo int */ int i; /* Tipo int[10] */ int a[10]; /* Tipo double[3] */ double d[] { .0, .1, .2 }; This is why, the size can be detected using function overloads:void f(int[10]) { std::cout << "Arreglo 10.\n"; } void f(int) { std::cout << "Entero.\n"; } f(a); // Muestra "Arreglo 10" f(i); // Muestra "Entero" f(d); // Error de compilacion, no existe funcion que acepte double[3] So your function obtener_longitud_array it could be a template that got the size of the arrangement this way:template <std::size_t N> std::size_t obtener_longitud_array(int[N]) { return N; } Or you could generalize it for different types https://es.stackoverflow.com/a/74499/2742 . But instead of re-inventing the wheel I would use the utility http://es.cppreference.com/w/cpp/types/extent belonging to the header http://es.cppreference.com/w/cpp/header/type_traits standard library:#include <iostream> #include <type_traits> int main() { int array_enteros[]={'9','8','7','6','5','4','3','2'}; std::cout << std::extent_v<decltype(array_enteros)> << '\n'; // 8 return 0; }

Let's start by texting it in a normal way.typedef std::map<std::string,int> arr; std::map<arr> array; // массив arr* pointer = &array["orange"]; // указатель I want you to agree on a way better and more beautiful. By the way, this code will be compiled by a majority of ++ compilators, and yours will not be, because not all compilators are properly transported. >> In the announcement. We need to write through the gap.I mean, it's just an element indicator. There's a need to stop and say that it's best to use the heterans, because they're meant for that. But at the lower level of the iterators, they're the same indexes, just the compiler has more information.The terator on the element map doesn't change unless you touch the map. Citation http://www.cplusplus.com/reference/map/map/operator%5B%5D/ The function accesses an element and returns a reference that can be used to modify its mapped value. i.e. with a map element index, the element itself can be modifiedConcurrently accessing other elements is safe.Moreover, this will not affect the fact that other functions modify other elements of this map.If the function inserts a new element, concurrently iterating ranges in the container is not safe.But if there's an element in the original map, the index can be damaged (and may not. The original says it's not safe.We'll follow up.The situation described will not change. In general, the variable "indicator" won't change, because changes in any map do not affect it. Even if the map is removed. The index is just a memory address. What's hiding behind the index is a separate story.The index, as I said above, is exactly the same. And the element's address on the map can change if you modify the parent's map. The operational memory system is certainly optimizing, but it does it at the level of physical addresses. And those addresses you work with are virtual. They do not change as a result of LO actions. It's not Java or NET, but it's hard to do that in Java, for example, there are no signs: There are unsafe operations at NET, there's probably a way to do that, but unsafe use is someone who understands what they're doing. I mean, just physically, in a microchemical memory, data can be stored in different places, even on a disc can be moved (apping). But the operating system makes it transparent for a applied software player. If you're going down to the Driver level, it's not that simple.Yes, the address will be the same until the parent card is modified.I don't think anyone's gonna answer that question. There's nothing wrong with changing the design of the compiler. With different LOs, you're out of the way. The visual studio is still compiling only one OS. (Yeah, I know you can do gcc, but this is another story.) But most likely, in the foreseeable future, even on different DSs, the situation will be stable. It is important that the compiler adhere to the standard and the library as well. You may well take/write a side-by-step map for which all the above will be wrong.
