C++ 使用类和构造函数并创建数组大小为3的对象名

我正在尝试创建一个包含三个数组的主对象。当我运行它时，它会显示所需的输出，但它会给出一个错误，之后的任何代码都不会运行。Grocery.exe 0x775 FC41F未处理异常：微软C++异常：STD:：BADYOLL在内存位置0x00 36E590.< /P>

    class GroceryItem {

    void set_qty_on_hand(int);// Assigns a value to the data member quantity_on_hand.
    void set_qty_purchased(int); // Sets qty_purchased to zero before a customer begins shopping.

您没有与我们分享尺寸值；然而，我猜你可能不到10。如果是这样的话，那么当您在Kmart3中循环时，它会崩溃

进行此更改应至少在我的测试中停止崩溃：

for (int i = 0; i < SIZE; i++)
{
    if (Kmart3[i].get_item_name().length() > 0)
        cout << Kmart3[i].get_item_name().c_str() << "\t" << Kmart3[i].get_item_price() << "\t" << Kmart3[i].get_qty_on_hand() << "\t" << Kmart3[i].get_qty_purchased() << endl;
}

当然，在代码运行之前，您还需要解决一些其他问题，我认为您的意思是让它运行；但是，这应该可以停止崩溃。

错误来自Kmart3输出。感谢您的回复，我实际上是以10的大小进行的，但我更改了一些内容，将大小改为3。当我用10号而不是3号时，导致了崩溃。
