How to separate the line and insert a vector on c+

The python could use a map and split method to separate the line into words. Maybe there's a built-in role in the pros?

May be:

std::vector<std::string> res;
std::istringstream ss(text);
std::string word;
while (ss >> word)

{

res.push_back(word);

}

Example of implementation, as I see. In detail, everything tried to describe how to organize and use methods and classes. It's an example, but not a solution. I'll show you how to use it, but put the logic on your own. from random import randint as ri from random import choice as ch класс дверь, при инициализации добавляем instance - имеется в виду либо артефакт, либо монстр class Door: def init(self, instance): self.instance = instance в данный класс мы передаем героя с его здоровьем и в зависимости от того что за дверью получаем результат его здоровья def openDoor(self, hero): if isinstance(self.instance, Artefact): hero.health += self.instance.force else: hero.health -= self.instance.damage что мы будем возвращить когда вызовем str() для объекта класса def __str__(self): return "Что за дверью: " + str(self.instance) класс для артефакта, ri это ранодмный Int в диапазоне см. import force - это сила, которая будет плюсоваться к силе героя class Artefact: def init(self): self.force = ri(10,80) def __str__(self): return "Artefact with " + str(self.force) класс для монстра, если все комментарии прочитаны, то тут будет ясно class Monster: def init(self): self.damage = ri(5,100) def __str__(self): return "Monster with " + str(self.damage) + " damage" class Hero: def init(self, health): self.health = health def __str__(self): return "Здоровье героя:" + str(self.health) создание игрового поля с дверьми doorSet = {} for i in range(10): instances = [Artefact(), Monster()] doorSet[i] = Door(ch(instances)) # см. import вверху что такое ch в переменной doorSet у нас набор с различными дверьми создадим героя c 25 hp hero = Hero(25) Now the hero is created, try to open the door and see what happens to health:# пример открытия двери doorSet[0].openDoor(hero) print(hero) >>Здоровье героя:45 It works. A few words about the main logic. I see that it is necessary to write a method to look at doors without opening them, i.e. not attached to the health of a hero and to compare to the health of a hero. How it looks to you.I.e. We have a door-to-door kit for the moment. How do you open them? Find the smallest monster, further compare to health, and if it goes to minus, find artifact, etc. The verification of the death of a hero can be used in the same method openDoorAnd in the hero's class itself, add a field of "alive" with a logical meaning, for example. Write classes and methods, and in basic logic, create objects and manipulate them through methods.

Segmentation fault is a mistake that occurs when there is a recording in a non-processed memory area.When str[i] is inserted, more symbols are likely to be inserted than 100, which is not sufficient. The number of symbols imposed must be checked. To meet this challenge, it is necessary to remembrance dynamically through calloc(s) or malloc(s), and if the capacity of the mass is not sufficient to double by realloc(s).#include <stdio.h> #include <stdlib.h> int main() { size_t capacity = 20, counter = 0; char str = (char)calloc(capacity, sizeof(char)); str[counter] = getchar(); while(str[counter] != '\n') { ++counter; if(counter == capacity) { capacity *= 2; str = (char*)realloc(str, capacity * sizeof(char)); } str[counter] = getchar(); } printf("the string is: >>%s<<\n", str); free(str); return 0; } I also recommend gettingchar(s) instead of scanf(s)That is how I promised to do this, there must be a very long line.

It worked out after I changed the python crypt code to ANSI.How am I supposed toFirst, the violin started without mistakes, but somehow the task planner couldn't get him straight. That's the situation I described.But then, after the computer's reboot, after a while, the violin has been launched with that mistake, no matter how manual I start it or through the planner.I was a little stumbled in the notebook trying to fix it, and while the violin kept, I got this:This file contains a Junicod version that will be lost if You keep this file as a ANSI file. To maintain data Junikod, press the button, and select one of the options. Continuation in the Junicode format. Continue.I did what it said, pressed the button. Cancellation and kept the file at utf-8, but the mistake remained. But after I changed the code of the text itself, not the file, everything worked out as well as the task planner, too. :'Oh, that's a great variety of coding, so much trouble it's delivered and delivered to date.

Here's a little LINQ:var uri = new Uri("http://frostsecurity.net/frost/frostupdater/version.txt"); var request = WebRequest.CreateHttp(uri); using (var responce = (HttpWebResponse)request.GetResponse()) using (var responceStream = responce.GetResponseStream()) using (var reader = new StreamReader(responceStream)) { var dict = reader.ReadToEnd() .Split(new[] {'\n'}, StringSplitOptions.RemoveEmptyEntries) .Select(l => l.Split(new[] {' ', '\t'}, StringSplitOptions.RemoveEmptyEntries)) .ToDictionary(a => a[0], a => a[1]); var result = dict["pb_live"]; } Hold it without LINQ, here's the inside. var dict = new Dictionary<string, string>(); string line; while ((line = reader.ReadLine()) != null) { if (string.IsNullOrWhiteSpace(line)) continue; var parts = line.Split(new[] {' ', '\t'}, StringSplitOptions.RemoveEmptyEntries); dict[parts[0]] = parts[1]; } var result = dict["pb_live"]; And https://ru.stackoverflow.com/q/416584/10105 the development of questions on SO does not justify itself.

If you can get your hands out of the line, you can use it. http://en.cppreference.com/w/cpp/regex :#include <ostream> #include <regex> #include <string> #include <vector> std::ostream& print(std::ostream& out, const std::string& format, const std::vector<std::string>& args) { std::regex re("[^%]+|%%|%\d+"); for (std::sregex_token_iterator i {format.begin(), format.end(), re, 0}, end; i != end; ++i) { std::string token {*i}; if (token == "%%") { // escaped % out << '%'; } else if (token[0] == '%') { // positional parameter unsigned long index = std::stoul(token.substr(1)); out << args.at(index-1); } else { // print as is out << token; } } return out; } Example of use:#include <iostream> int main() { char array[] = u8"Антон|15|Архангельске"; print(std::cout, u8"Привет, меня зовут %1, мне %2 лет. Я живу в %3", split(array, '|')) << std::endl; } where split() may also be determined using regex, or simply when the divider char♪ https://stackoverflow.com/q/5167625/4279 :#include <sstream> #include <string> #include <vector> std::vector<std::string> split(const std::string& s, char sep) { std::vector<std::string> args; std::istringstream ss {s}; for (std::string arg; std::getline(ss, arg, sep); ) args.push_back(arg); return args; } Example of launch:$ c++ -std=c++11 *.cc && ./a.out Привет, меня зовут Антон, мне 15 лет. Я живу в Архангельске For comparison, it is possible to look at the (intelligent) version which, by hand, handles the format:std::ostream& print(std::ostream& out, const std::string& format, const std::vector<std::string>& args) { bool in_format = false; size_t index = 0; for (char c : format) { if (in_format) { if (std::isdigit(static_cast<unsigned char>(c))) { // build up index index *= 10; index += c - '0'; } else { in_format = false; if (index) { // full number, print corresponding arg out << args[index-1]; index = 0; if (c != '%') { out << c; // print as is } } else if (c == '%') { // %% case -- print % literally out << c; } else { // error XXX ignore out << c; } } } else if (c == '%') { in_format = true; } else { // print as is out << c; } } if (index) out << args[index-1]; return out; } This option makes it easier to make a mistake and makes it more difficult to trace as extreme cases.

I know how you can do with opencv-python in real time.from cv2 import cv2 from pyzbar.pyzbar import decode cap = cv2.VideoCapture(0) cap.set(3, 360) cap.set(4, 360) while True: _, frame = cap.read() for code in decode(frame): data = code.data.decode('utf-8') print(data) cv2.imshow('QrLinkDetection', frame) cv2.waitKey(1) When this code is launched, you'll have a window of translating images of your web camera if you show you to QrCode's web camera, you'll have a consol where it leads. I think that's possible with a picture like that. ♪ ♪

First, the data you provide are not correct json - the brackets and commas are not correctly displayed.Secondly, why do you need all this "if you're on the list, so if you don't have it, it's an edac"?You need to find the maximum val, so you're looking for it:import json data = ''' {"fig": { "types": { "sizes": [{ "type": "a", "val": 200 }, { "type": "b", "val": 500 }, { "type": "c", "val": 600} ] }}} ''' data = json.loads(data) max_item = max(data['fig']['types']['sizes'], key = lambda item: int(item['val']) ) print("Тип с максимальным значением: %s" % max_item['type']) print("Максимальное значение: %s" % max_item['val'])

First in the tags you put that is maptolib, however the error message clearly indicates that the error comes from the struct function.In accordance with the documentation of this function:The buffer’s size in bytes must match the size required by the format, as reflected by calcsize().Therefore the error must come from "sound_data = wave_file.readframes(data_size)" which in turn depends on "data_size = wave_file.getnframes()"Since you don't matter any modules that call the wave I imagine you do it from another point of the code, also attending again to the documentation of struct the buffer is determined by the value that removes "struct.calcsize(fmt)" so that it would investigate that values and what type of data return "sound_data" and "data_sfize", it would also be good to see that it returns "apackt_ and corresponding to what returns calcsize()

I wouldn't expect any kind of acceptance prognosis just on the date. People ' s attitudes will depend more on the weather (sand, pastur, rain) on some news, personal circumstances, etc. The only thing that comes to mind is to smash the day of the week as a separate sign, because on Friday and Saturday, people tend to feel better than, say, Monday.In addition, you should transpose DataFrame, add a date as a number (most algorithms of machine can't work with a type of data. datetime) and add the day of the week as a sign (the table):df = (df.T .assign(date=(pd.to_datetime(df.columns).astype(np.int64)//10**9), week_day=pd.to_datetime(df.columns).weekday) .reset_index(drop=True)) result:In [74]: df Out[74]: angry disgust fear happy neutral sad surprise date week_day 0 8.00 0.0 8.00 0.00 12.00 68.00 4.00 1522972800 4 1 0.00 0.0 0.00 0.00 71.43 28.57 0.00 1523059200 5 2 0.00 0.0 38.89 5.56 5.56 50.00 0.00 1523145600 6 3 33.33 0.0 8.33 0.00 16.67 41.67 0.00 1523232000 0 4 0.38 0.0 48.11 1.52 46.97 2.65 0.38 1523318400 1 5 0.00 0.0 14.00 0.00 55.00 30.00 1.00 1523404800 2 6 5.00 0.0 18.33 5.00 26.67 45.00 0.00 1523491200 3 7 0.00 0.0 40.00 0.00 30.00 30.00 0.00 1523750400 6 8 0.00 0.0 20.00 0.00 53.33 26.67 0.00 1523836800 0 9 9.52 0.0 28.57 0.00 19.05 42.86 0.00 1523923200 1 Poles date and week_day will be your input data.Xand the rest are your weekends / predicted data.Y)

You can add the description column conditionally, that is, only if your variable representing the description value is filled that we will enter the data in the column.MySqlCommand command = new MySqlCommand("INSERT INTO item (id_item, " + "nome, " + (!string.IsNullOrWhiteSpace(descricao) ? "descricao, " : "") + "imagem, " + "categoria, " + "VALUES(@id_item, " + "@nome, " + (!string.IsNullOrWhiteSpace(descricao) ? "@descricao, " : "") + "@imagem, " + "@categoria); ", conexao); In this example I considered that its variable is called descricao.
