我遇到了这样一个问题：我用PyQt5写了一个程序，它运行良好，我在pyinstaller的帮助下制作了一个.exe文件，因为我会经常使用它，当我运行可执行文件时，除了它，控制台打开。是否有可能以某种方式阻止控制台的打开？

先感谢您

面临这样一个问题：是否有可能以某种方式转换以下代码使用string

#include <iostream>
#include <string>

using namespace std;

int main()
{
    string str[3] = { "Anna", "Max", "Dan" };
    for (int i = 0; i < strlen(str); i++) {
        cout << str[i] << " ";
    }
}

编码使用char？我知道是什么char将单词分成字符，所以我不确定这是否可能。请帮我弄清楚！

任务设置如下：你需要在一个棋场上放置8个皇后，这样它们就不会受到对方的攻击。

我在 C++ 中实现了这个任务，如下所示：

#include <iostream> 
using namespace std;

int main() {
    setlocale(LC_ALL, "ru");
    int q[8], c, i;
    int count = 1;
    q[0] = 0;
    c = 0;


NC:
    c++;
    if (c == 8) goto print;
    q[c] = -1;


NR:
    q[c]++;
    if (q[c] == 8) goto back;

    for (i = 0; i < c; i++) {
        if ((q[i] == q[c]) || ((c - i) == abs(q[c] - q[i]))) goto NR;
    }
    goto NC;


back:
    c--;
    if (c == -1) return 0;
    goto NR;

print:
    cout << "---------------------------------";
    cout << endl;
    for (int i = 0; i < 8; i++) {
        for (int j = 0; j < 8; j++) {
            if (j == q[i]) {
                cout << "| Ф ";
            }
            else {
                cout << "|   ";
            }
        }
        cout << "|";
        cout << endl;
        cout << "---------------------------------";
        cout << endl;
    }
    system("pause");

    return 0;
}

告诉我如何修复我的代码以便我不使用goto？我将不胜感激。

如何在 Python 中找到 .txt 类型的文件，同时文件的名称以“result”开头。也就是说，在我的文件夹中的文件是：result_275.txt, result_351.txt,task.txt

程序如何找到这些文件并例如显示它们的名称？

如何构建每秒更新的已用磁盘空间的散点图？我很乐意提供帮助！

我们需要这样的时间表，因为对于应用程序的运行，磁盘空间不会发生显着变化（除非我们删除一些东西）。

单击按钮时是否可以执行两个功能？我请求你的帮助！

我能够实现太平庸的代码，以便将数组循环移动一个值。您需要以某种方式通过 k 值实现移位，并且您不能使用任何函数，只能使用循环。我请求你的帮助！

我的代码：

#include <iostream>

using namespace std;

int main()
{
    const int N = 4;
    int arr[N] = { 1, 2, 3, 4 };

    int el = arr[0];
    for (int i = 1; i < N; ++i)
        arr[i - 1] = arr[i];
    arr[N - 1] = el;

    for (int i = 0; i < N; ++i)
        cout << arr[i] << " ";
}

我最近开始学习 C++，我的代码很蹩脚。您需要输出以下内容：

我怎样才能缩短我的代码（我相信你可以）？

#include <iostream>
#include <string>

using namespace std;

int main() {
    setlocale(LC_ALL, "ru");

    string simvol = "*";
    
    int control = 7;

    for (int j = 0; j < control; j++) {
        cout << simvol << " ";
    }
    cout << endl;
    for (int j = 0; j < control; j++) {
        if ((j == 0) || (j == control - 1)) {
            cout << "  ";
        }
        else {
            cout << simvol << " ";
        }   
    }
    cout << endl;
    for (int j = 0; j < control; j++) {
        if ((j == 0) || (j == 1) || (j == control - 1) || (j == control - 2)) {
            cout << "  ";
        }
        else {

        }
    }

如何跟踪应用程序的打开副本并关闭主要副本？

我读到互斥量和信号量用于此目的，但我不知道如何将其与PyQt5连接起来。

例如，我启动一个应用程序，启动它后，我再次打开它。例如，我如何警告应用程序已经在运行？

我希望能得到你的帮助。

以下情况：我需要以某种方式，使用注册表，在5工作几分钟后关闭程序并要求，例如，购买主要订阅。

我所做的最多是在一定数量的启动后实施关闭。
