How is it right to count the length of the line containing the kirillian?

Analeea last edited by
```
std::string str1 = "Test";
std::string str2 = "тест";
```
I noticed that
str1.size() = 4♪ str2.size() = 8
How can you read that right?

Kirillica has two bays for each symbol, i.e., used by Yunikod. Latina and other symbols are on one side of the sign, i.e. code ASCII.
Maybe you need a length.
Look. https://ravesli.com/urok-202-dlina-i-yomkost-std-string/

PHP can be done for example:$text = "Допустим здесь ваш текст из 15 символов"; $text = mb_substr($text,0,12, 'UTF-8'); //12 это кол. знаков echo $text.'...'; https://ru.stackoverflow.com/questions/190970/%D0%9F%D0%BE%D1%81%D1%82%D0%B0%D0%B2%D0%B8%D1%82%D1%8C-%D1%82%D1%80%D0%BE%D0%B5%D1%82%D0%BE%D1%87%D0%B8%D0%B5-%D0%B2-%D0%BD%D0%B5-%D0%B2%D0%BC%D0%B5%D1%81%D1%82%D0%B8%D0%B2%D1%88%D0%B5%D0%B9%D1%81%D1%8F-%D0%B2-%D0%BF%D0%BE%D0%BB%D0%B5-%D1%82%D0%B5%D0%BA%D1%81%D1%82

Each container uses its internal use (nginx, www-data)It's not necessary in the container. You've got one container trial, you don't additional users. You don't need to segregate resources, you don't mind if the user goes into the system files because the broken container reset in a second.Containers are subject to a very large philosophy, one of whose planes is well reflected in the concept of the twelfth de facto annex. When you write the application correctly, the application itself does not use the file system at all - the logs go to stdout or the log collector, the files go to the file stores, the data to the database. If you have problems with access rights, you write something on the CD for some reason, and you do it for nothing. It's justified because the transition to a 12-factor application requires a good cost, but the truth remains the same - you just don't need to write anything on the CD, have a few users, start a few processes.

I fixed it. Maybe someone needs to:SpinBox'a code:SpinBox { id: spBox_gear_part1 x: 258 y: 157 width: 200 height: 40 font.pointSize: 19 from: 0 value: 0 to: 20000000 wrap: true editable: true wheelEnabled: true Material.theme: Material.Dark Material.foreground: "white" Material.accent: "#2196F3" property int decimals: 3 property real realValue: value / 1 validator: DoubleValidator { bottom: Math.min(spBox_gear_part1.from, spBox_gear_part1.to) top: Math.min(spBox_gear_part1.from, spBox_gear_part1.to) } textFromValue: function(value, locale) { return Number(value / 1000.0).toLocaleString(locale, 'f', spBox_gear_part1.decimals) } valueFromText: function(text, locale) { return Number.fromLocaleString(locale, text) * 1000.0 } } And for the C+++, I'm already doing this:In port:property double spBoxValue_Gear_Part1: mountForm.spinBox_Gear_Part1.value / 1000 To read from port:onSend_Gear_Part1: console.log(mountForm.spinBox_Gear_Part1.value = value * 1000

Replace the flag. QRegularExpression::MultilineOptionwhich changes the behaviour of metasymwalls ^ (first line) and $ (end of line), on http://doc.qt.io/qt-5/qregularexpression.html which alters the attitude of the point (which forces it to find signposts/returns).Also .+ replace by .+? to search the nearest right Continue your search on Amazon♪In addition, (?<=a).+?(?=b) Better rewrite as a(.+?)band then, instead of getting the right meaning throughQRegularExpression re("<div\\s+id=\"p0\"\\s+class=\"productContainer\"(.+?)Continue your search on Amazon", QRegularExpression::DotMatchesEverythingOption); QRegularExpressionMatch match = re.match(site); if (match.hasMatch()) { QString day = match.captured(1); // Группа №1 содержит искомое значение }

Use the operator. like:SELECT * FROM users WHERE user_name LIKE '%Петр%' On request sqlite3 It looks like this. % It's a specialty. liketo be searched in any part of the text)text = '%Петр%' connect.execute("SELECT * FROM users WHERE user_name LIKE ?", [text]).fetchall() Sqlite 3.7.15 can be used https://www.sqlite.org/lang_corefunc.html#instr (I don't need to add. %to find inside the line, different from liketext = 'Петр' connect.execute("SELECT * FROM users WHERE instr(user_name, ?) > 0", [text]).fetchall()

You should read about the function. http://php.net/unserialize ♪Next code: print_r(unserialize('a:7:{i:800;s:40:"2a5cc72ffea060a4548ae03d6076f4bd_800.jpg";i:500;s:40:"2a5cc72ffea060a4548ae03d6076f4bd_500.jpg";i:300;s:40:"2a5cc72ffea060a4548ae03d6076f4bd_300.jpg";i:295;s:40:"2a5cc72ffea060a4548ae03d6076f4bd_295.jpg";i:75;s:39:"2a5cc72ffea060a4548ae03d6076f4bd_75.jpg";i:40;s:39:"2a5cc72ffea060a4548ae03d6076f4bd_40.jpg";i:0;s:36:"2a5cc72ffea060a4548ae03d6076f4bd.jpg";}')); He'll find out:Array ( [800] => 2a5cc72ffea060a4548ae03d6076f4bd_800.jpg [500] => 2a5cc72ffea060a4548ae03d6076f4bd_500.jpg [300] => 2a5cc72ffea060a4548ae03d6076f4bd_300.jpg [295] => 2a5cc72ffea060a4548ae03d6076f4bd_295.jpg [75] => 2a5cc72ffea060a4548ae03d6076f4bd_75.jpg [40] => 2a5cc72ffea060a4548ae03d6076f4bd_40.jpg [0] => 2a5cc72ffea060a4548ae03d6076f4bd.jpg ) The information you need is stored in a mass under the key. 800♪ Save the performance of the function unserialize and work with him.For example:$images = unserialize('тут ваша строка'); print $images[800];

It's not very clear what you want. Replace the letters with random symbols? Something like that?char myChar[] = "Something"; for(char * c = myChar; *c; ++c) { *c = "&@?!#%^*"[rand()%8]; }

Elegant? remove_if + erase range.erase In general, the component is disabled by the terator: https://en.cppreference.com/w/cpp/container/deque/erase #include <deque> #include <iostream> #include <algorithm> const int value = 50; int main( ) { std::deque<int> c{0, 10, 20, 30, 40, 50, 60, 70, 80, 90}; for (auto &i : c) std::cout << i << " "; std::cout << '\n'; c.erase(std::remove_if(c.begin(),c.end(), [](auto x){ return x == value || x == value + 10; }), c.end()); for (auto &i : c) std::cout << i << " "; std::cout << '\n'; }

This behaviour occurs when the Ubuntu repository is installed - the module is not working correctly. ClangCodeModel You can turn it off. Справка -> О модулях...: But I recommend that you remove this version of Qt and set it off. https://www.qt.io/download-qt-installer?hsCtaTracking=99d9dd4f-5681-48d2-b096-470725510d34%7C074ddad0-fdef-4e53-8aa8-5e8a876d6ab4

There's no UTF8, there's just baytes. Lines, whole, UTF8 - interpretation of some blue sequence in memory. Next, the size of the blunt algorithm is the character of the algorithm. AES, for example, works with blocks in 128 battles (16 Byte), respectively the size depends on algorithm. The breakdown of data on blocks is a consistent sample of the corresponding number of byte. The removal of the block into two parts is a completely similar operation.

Your EDT method has a small big problem and I explain it to you by comment lines: void EDT(ifstream& arch_Datos){//EDT=Ejercicios con los DaTos string texto; int i=0; // Correcto i tiene un valor inicial = 0 int suma; // Variable no inicializada cualquier valor. float media; // Igual al anterior // int longitud[v]; // Arreglo sin inicializa int * longitud = new int[v]; // Nueva versión (ver comentario de @eferion while(!arch_Datos.eof()){ getline(arch_Datos,texto); longitud[i]=texto.length(); // Asigna un valor correcto. cout<<longitud[i]<<endl; i++; } int c=0; // Correcto. while(c<v){ // suma = suma + que valor puede tener esta variable no inicializada. Puede como no puede estar en 0. Por lo tanto, tu suma siempre debería salir como resultados diferentes suma=suma+longitud[c];//lugar donde le entro los datos a suma c++; } **cout<<suma<<endl;**//lugar del problema. El problema viene de mas arriba, aqui solo lo presenta arch_Datos.close(); } You have to initialize your variables: int suma = 0; float media = 0.0f;
