因此，也可以在析构函数中安全地使用断言。

Thus, the assertions can be used safely in destructors, too.

这是可能的析构函数抛出一个异常。

It is possible for the destructor to throw an exception.

我们还需要添加一个析构函数的类。

We also need to add a destructor to the class.

youdao

对错误类型的析构函数进行了调用。

A call is made to a destructor of incorrect type.

youdao

一个类只能有一个析构函数。

A class can only have one destructor.

youdao

如果析构函数为空，只会导致性能降低。

If the destructor is empty, this simply results in a loss of performance.

首先，调用将要被删除的对象的析构函数。

First, the destructor of the object that's being deleted is called.

youdao

尽管析构函数是一种方法，但它不能有参数。

Although a destructor is a method, it cannot have parameters.

youdao

当函数结束的时候，对象的析构函数就会被调用。

When the function end, the constructor of the object will be called.

youdao

构造函数和析构函数是面向对象程序设计中的难点。

The construction function and the destruction function are difficult parts in object-oriented programming design.

youdao

例如，无法在析构函数或终结器上请求一个新的槽。

For example, a new slot cannot be requested on a destructor or finalizer.

因此，从第一个例子不同，我们需要实现一个析构函数。

So, different from the first example, we need to implement a destructor.
