c++ - 嵌套的 for 循环没有完成它们的循环

Question

当我运行程序的这一部分时，唯一可以工作的循环是最后一个涉及“week”变量的 for 循环。

cout << "Enter Building: ";
    cin >> building;
    cout << "\n";

    cout << "Enter Room: ";
    cin >> room;
    cout << "\n";

    cout << "Enter Numeric Month: ";
    cin >> monthIndex;
    monthIndex = monthIndex - 1;
    cout << "\n";

    cout << "Enter Week: ";
    cin >> week;
    cout << "\n";

    for (;building <= 30; building++)
    {
        for (;room <= 24; room++)
        {
            for (;monthIndex <= 11; monthIndex++)
            {
                for (;week <= 4; week++)
                {
                    cout << "Building: " << building << "\n";
                    cout << "Room: " << room << "\n";
                    cout << "Month: " << month[monthIndex] << "\n";
                    cout << "Week: " << week << "\n\n";
                }
            }
        }
    }

示例输出:

按1打印所有票本

按 2 打印特定票簿

按3退出程序

2 菜单选择

进入大楼:26

进入房间:20

输入数字月份:8

输入星期:2

建筑:26房间:20月份:八月周:2

建筑:26房间:20月份:八月周:3

建筑:26房间:20月份:八月周:4

Answer 1

您需要在最后一个 for 循环结束时将 week 设置为 1。
