c++ - 在构造函数 C++ 中创建指向对象的指针

Question

我想知道如何在 C++ 的构造函数中创建指向新创建对象的指针？

一个类的地址是什么？

class MyClass
{
    public:
};

class MyClass2
{
    public:
    //I need a pointer to the created object
    MyClass2 *pObjectName;

    //Constructor
    MyClass2()
    {
        pObjectName = &//I have no clue how to get the adress of the (not yet) created object.
    }
};

int main()
{
    //The way it works
    //Makes Object
    MyClass *pObject;
    MyClass Object;
    //pObject points to Object
    pObject = &Object;
    //Prints adress of Object
    printf("%p", pObject);


    //The way I would like to see it work
    MyClass2 Object2;
    //Prints adress of Object
    printf("%p", Object2.pObjectName);

}

Answer 1

应该是:

MyClass2()
{
    pObjectName = this;
}

但是您不需要那样做。 this 指针被隐式传递给类的每个非静态成员函数。
