C++ 传递类的指针数组时出现分段错误

我遇到了一个相当令人沮丧的问题，我试图将充满对象的指针数组的内容传递给另一个类，以便打印数组的内容，但无论我尝试如何改变传递数组的方式，我始终会遇到分段错误。我已经到处寻找有类似问题的人，但我没有找到有相同问题的人，但如果这是一个重复的问题，我仍然道歉！ 无论如何，我这两个类的代码是

在堆栈上创建一个新的
事件
e
。然后保存指向该局部变量的指针。一旦函数返回，该指针将不再有效，使用它将导致未定义的行为（例如seg错误，但它可以执行许多其他操作）

若要解决此问题，请确定这些数组是指针数组还是对象数组。如果您确实想使用指针，则需要确定如何控制指针的生命周期。或者，您可以使用智能指针，为您管理对象的生命周期

注意：这只是我突然想到的第一件事，可能还有其他问题。

添加返回类型之前在程序中乱搞时，我一定是删除了返回类型，忘记了将其添加回去…尽管如此，我仍然在返回类型中遇到分段错误，并且它也发生在我的deleteEvent函数中，这让我相信（可能完全错误？）这个问题与我传递信息的方式有关。您需要告诉我分段错误是何时发生的。分段错误是在我调用displayEvent函数中的printEvent函数时发生的。谢谢，这听起来似乎正是错误所在。我没有在arra上使用指针数组的具体附件指针的数组是我最先建议的，所以我就这么做了，你认为把指针数组转换成对象数组会有多困难？应该是很简单的。要考虑的是在特定的一天没有事件时发生的事情。对象您需要有另一种检查方法。这可能很简单，只需将
说明设置为空白，然后不打印任何带有空白说明的内容。好的，谢谢您的回复！
