new[]和delete[]调用多少次来分配和释放内存?

C++ ,每次 new [] 使用或 delete []

例如,参加以下课程:

#include <iostream>

class Cell
{
public:
    Cell() : _value(2)
    {
        std::cout << "Cell being made!\n";
    }
    ~Cell()
    {
        std::cout << "Cell being freed!\n";
    }

    const int& getVal() const
    {
        return _value;
    }
private:
    int _value;
};

new[] 使用,如下所示

Cell* cells = new Cell[5];

Cell being made!
Cell being made!
Cell being made!
Cell being made!
Cell being made!

后来什么时候 delete[] 是在 cells 指针,我明白了:

Cell being freed!
Cell being freed!
Cell being freed!
Cell being freed!
Cell being freed!

我的问题是,在每个构造函数调用中,内存大小是否等于分配的一个类实例?就像你做的那样 new Cell[5] 分配内存5次?或者它只分配一次,然后作为一个函数调用对构造函数进行5次调用?与相同 ,它是否在每次析构函数调用时释放?
