当类型为类时,我需要一些矢量向量的帮助。 “loadTruck”是我的班级。我想按照以下顺序将我的类“loadTruck”中的值存储到2D矢量中:vector(truck,print)。 “truck”和“print”都是类“loadTruck”的类型。我想访问这个向量:例如,假设“print”是包,“truck”是卡车。我想获得有关包裹在卡车1中的信息,包裹号为20.我完全对此感到困惑。
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);
}
带3D阵列的版本,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ 现在programm运行良好,但数组并不是一个好主意,但我希望它能帮助你理解我想做什么。我需要使用向量,因为我无法定义数组的前2个元素,它依赖于algorythm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3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);
}
此致
答案 0 :(得分:0)
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);
}
但是很难从你的问题中看出来。
