全部问题

几个输入字段分别包含从 0 到 4 的数据。这些输入中总共输入了多少个单位，div 中总数的百分比被添加到这个div id="price1"输入中，input id="price"

假设价格是 500 卢布

在输入框中输入 5

一个单位的投入=2%

500+10% 或 500x1.1

结果四舍五入到十分位

执行该函数时，文本文件只是被简单地删除，也就是将整个文件转换为“”。我该如何解决这个问题，也许我错过了什么？在运行此功能之前我没有写任何可能导致此结果的内容。

我找不到代码中的错误，改变时数组输出不正确。

static void Main(string[] args)
{
    Console.WriteLine("Введите размерность массива");
    int n = Convert.ToInt32(Console.ReadLine());
    int[] m = new int[n * 2];
    int k = 0;
    Random r = new Random();
    Console.WriteLine("Начальный массив");

    for (int i = 0; i < n; i++)
    {
        m[i] = r.Next(-100, 100);
        Console.Write("{0,5}", m[i]);
    }
    Console.WriteLine();

    int a = 0;
    int count = 0;
    for (int i = 0; i < n; i++)  
    {
        int d = 0;
        a = Math.Abs(m[i]);
        while (a > 0)
        {
            if (a % 10 == 1)
            {
                d = 1;
            }
            a /= 10;
        }
        if (d == 1)
        {
            count++;

            for (int p = n + count - 1; p > i + count - 1; p--)
            {
                m[p] = m[p - 1];
            }

            m[i + count - 1] = k;
            i++;

        }
    }

    Console.WriteLine("Измененный массив");
    for (int i = 0; i < n + count; i++)

我在浏览器控制台中输入以下代码http://localhost:8080/
：

async function my() {

   document.getElementsByTagName("body")[0].innerHTML = "";     
   let p = document.createElement('pre');
   
   let cnt = 0;

   for (let i = 0; i < 10000000; i++) {
    
    let now = new Date();
    let start_sec = now.getSeconds();

    if (start_sec % 5 == 0) {
        cnt = cnt + 1;
        let dmy =  now.getDate() + "." +  (now.getMonth() + 1) + "." + now.getFullYear();
        let hms_ms = now.getHours() + ":" +  now.getMinutes() + ":" + start_sec + "__" + now.getMilliseconds();

        p.innerHTML = "{\"site\": \"site_01\", \"id\": " + cnt + ", \"data\": ["  + dmy + ", " + hms_ms  + "]}";
        document.body.append(p);
    }
    
    await sleep(1000);
   }
}

function sleep(ms) {
   return new Promise(resolve => setTimeout(resolve, ms));
}

my();

我每 5 秒更新一次时间并将其显示在浏览器窗口中，例如，如下所示：

{"site": "site_01", "id": 62, "data": [17.4.2025, 21:4:35__576]}

代码运行正常，但是当延迟时间减少（await sleep(1000);
例如 200 毫秒）时，数据id和__ms。

如何修复代码以使其以尽可能小的延迟工作，例如最多 100 毫秒？

剧透我不明白如何在这里做到这一点（对于代码的第二个版本）：

my();
function my() {
    
    document.getElementsByTagName("body")[0].innerHTML = "";     
    let p = document.createElement('pre');
    let cnt = 0;

    (function iterate(i) {
        
        if (i < 10000000) {
        let now = new Date();
        let start_sec = now.getSeconds();

        if (start_sec % 5 == 0) {
            cnt = cnt + 1;
            let dmy =  now.getDate() + "." +  (now.getMonth() + 1) + "." + now.getFullYear();
            let hms_ms = now.getHours() + ":" +  now.getMinutes() + ":" + start_sec + "__" + now.getMilliseconds();

            p.innerHTML = "{\"site\": \"site_01\", \"id\": " + cnt + ", \"data\": ["  + dmy + ", " + hms_ms  + "]}";
            document.body.append(p);
         }
         setTimeout(function() { iterate(i + 1); }, 10);
         }
    })(0);
}

我正在编写一个游戏并创建了一个地图加载器和日志。加载一个块只能有效一次，当再次加载时一切都会崩溃。代码：

    logout << "[CORE]: [LOAD]: [LOADCLUSTER]: <info>: in_time: [" << (GetTime().c_str()) << "]: Entered in LoadCluster function" << '\n';
    ifstream in_data;
    string nameclst = "files/worldinfo/cluster_" + to_string(x) + "_" + to_string(y) + ".clst";
    logout << "[CORE]: [LOAD]: [LOADCLUSTER]: <info>: in_time: [" << (GetTime().c_str()) << "]: Loading data from: " << nameclst << '\n';
    in_data.open(nameclst, ios::in);
    cout << "reading information from cluster: " << nameclst << "\n";
    string in_dstr = "";
    loadedCluster = {x, y};
    unsigned int line = 0;
    while(1)
    {
        getline(in_data, in_dstr);
        if(in_dstr == "end")
            break;
        if(in_dstr == "start")
            getline(in_data, in_dstr); line++;
        if(in_dstr == " "){
            logout << "[CORE]: [LOAD]: [LOADCLUSTER]: <error>: in_time: [" << (GetTime().c_str()) << "]: File: " << nameclst << " breaked or have no information" << '\n';
            MessageBox(NULL, (string("Cannot load information from cluster: ") + (nameclst)).c_str(), "Engine error", MB_ICONWARNING | MB_OK);
            return 1;
            break;
        }
        //обработка строки
        line++;
        _sleep(1);
    }

日志通常都很糟糕。如果通过 IDE 运行它，它会读取并重写所有日志，但如果在没有 IDE 的情况下通过 exe 运行它，则在进入该函数时一切都会崩溃。代码：

void CreateNewLog()
{
    string witinglogs = "";
    witinglogs += "[SYSTEM]: <info>: in_time: [" + string(GetTime().c_str()) + "]: CORE started" + '\n';
    witinglogs += "[CORE]: [LOGS]: <info>: in_time: [" + string(GetTime().c_str()) + "]: Mathing logs" + '\n';
    ifstream logCount("logs/logCount.math");
    logout.close();
    ifstream login("logs/latestLog.log");
    string logs;
    getline(logCount, logs);
    int logsc = stoi(logs);
    logCount.close();
    ofstream logCounte("logs/logCount.math");
    logCounte << logsc + 1;
    witinglogs += "[CORE]: [LOGS]: <info>: in_time: [" + string(GetTime().c_str()) + "]: Mathed " + to_string(logsc) + " logs" + "\n";
    string logtr = "logs/Log#" + to_string(logsc) + ".log";
    ofstream logOld(logtr);
    string readedLog = "";
    getline(login, readedLog);
    witinglogs += "[CORE]: [LOGS]: <info>: in_time: [" + string(GetTime().c_str()) + "]: Rewriting logs" + "\n";
    int lines = 0;
    while(readedLog != "[QUIT]")
    {
        lines++;
        if(readedLog == "[QUIT]" || lines >= 100000)
            break;
        logOld << readedLog << '\n';
        getline(login, readedLog);
    }
    logOld << "[QUIT]";
    witinglogs += "[CORE]: [LOGS]: <info>: in_time: [" + string(GetTime().c_str()) + "]: Rewrited " + to_string(lines) + " lines" + "\n";
    logOld.close();
    login.close();
    logout.open("logs\\latestLog.log", ios_base::trunc);
    logout << witinglogs;
}

我使用 IDE Code::Blocs。
