当类型是类时，我需要一些关于向量向量的帮助。“loadTruck”是我的课。我想按以下顺序将我的类“loadTruck”中的值存储到二维向量中：向量（卡车，打印）。“卡车”和“打印”都是“loadTruck”类的类型。我想要访问这个向量：例如，让我们说“打印”是包装，“卡车”是卡车。我想获取有关卡车 1 中包裹的信息，包裹 ID 为 20。我对此感到非常困惑。

vector<vector <loadTruck>> jedinecTruck;
loadTruck truck;

while (warehouseIsEmpty == False)
{
    truck.resetTruck();
    for (int i = 0; i < numOfPackages; i++)
    {
        vector<loadTruck> print;
        if (store2D[i].checkIfPackageIsThere() == true)
        {
            truck.setPackageSize(store2D[i].getPackageWidth(), store2D[i].getPackageHeight());
            if (truck.checkIfPackageCanBeLoaded() == true)
            {
                print.push_back(truck);
                truck.loadPackageInTruck();
                store2D[i].deletePackage();
            }
        }
    }
    jedinecTruck.push_back(truck);

}

3D数组版本，\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\这不是一个好主意，但我希望它能帮助你理解我想要做什么。我需要使用向量，因为我无法定义数组的前 2 个元素，它取决于算法并且总是在变化。对于这个例子，我假设前两个元素将被静态定义。第三个元素总是有 4 个组件。

    vector<loadTruck> jedinecTruck;
loadTruck truck;

int array[1][3][4];

while (wharehouseIsEmpty == false)
{

    truck.resetTruck();
    for (int i = 0; i < numOfPackages; i++)
    {
        if (store2D[i].checkIfPackageIsThere() == true)
        {
            truck.setPackageSize(store2D[i].getPackageWidth(), store2D[i].getPackageHeight());
            if (truck.checkIfPackageCanBeLoaded() == true)
            {
                truck.loadPackageInTruck();
                store2D[i].deletePackage();
                array[0][i][0] = truck.getActualX1();
                array[0][i][1] = truck.getActualX2();
                array[0][i][2] = truck.getActualY1();
                array[0][i][3] = truck.getActualY2();
            }
        }
    }
    jedinecTruck.push_back(truck);
  }

也许这更接近你想要做的事情：

vector<vector <loadTruck>> jedinecTruck;
loadTruck truck;

while (warehouseIsEmpty == False)
{
    truck.resetTruck();
    vector<loadTruck> print;
    for (int i = 0; i < numOfPackages; i++)
    {
        if (store2D[i].checkIfPackageIsThere() == true)
        {
            truck.setPackageSize(store2D[i].getPackageWidth(), store2D[i].getPackageHeight());
            if (truck.checkIfPackageCanBeLoaded() == true)
            {
                print.push_back(truck);
                truck.loadPackageInTruck();
                store2D[i].deletePackage();
            }
        }
    }
    jedinecTruck.push_back(print);

}

不过，从你的问题中很难看出。
