Arduino C++ 析构函数? [英] Arduino C++ destructor?

问题描述

我知道在 Arduino 中你不能使用 delete.那么C++类中定义的析构函数什么时候被调用?

I know that in Arduino you can't use delete. So when does the destructor defined in C++ classes gets called?

同样，如果我想创建一个指向数组的指针，我将不得不使用 malloc 和 free?

Similarly, if I want to create a pointer to array, I would have to use malloc and free?

推荐答案

析构函数在对象被销毁时被调用.对于自动(堆栈上)变量，它在离开其作用域 ({}) 后被调用.阅读有关自动变量的更多信息.

The destructor is called when the object is destroyed. For automatic (on stack) variables, it's called after leaving its scope ({}). Read more about automatic variables.
