Question

I’m wonder to know is it possible to delete an object through destructor method?

Constructor and destructor of my class:

class cal
{
    public:
        cal()
        {
            days = 0;
            day = 1;
            month = 1;
            year = 1300;
            leap = true;
        };
        ~cal()
        {
            delete this;
        }
}*calendar = new cal;

How can I delete this pointer through class?

P.S

I forgot to write the following code

cal *calandar = new cal[];

I want to use it in heap not stack

I want to use this class (objects) frequently (many of that object) imagine how many time should I write delete and it make hard understanding, troubleshooting and tracing codes I want them to been destroyed automatically (in heap)

I used following code in my class when I exec “delete[] calendar” it reduce my rams occupied (amount of ram that is used) does it work properly (destroy all objects) by exiting program? Because I use GNU/Linus and it destructs all objects with or without that lines I’m concern about leaking in windows

void DisposeObject() { delete this; }

You can write the code like this:

class cal
{
    public:
        cal()
        {
        };
        ~cal()
        {
        }
        void DisposeObject()
        {
           delete this;
        }
}

And it will call your destructor.

You should not call delete this from your destructor since it will call the destructor recursively, possibly leading to a stack overflow. Anyway, the code you wrote suffers from undefined behavior.
