Destructors
You
all must have heard about constructors, it's uses and properties. If you
haven't then I recommend you to first read the article about constructors (link
given below)
https://codingwinds.blogspot.com/2020/08/constructors-and-destructors-in-c-c.html
So,
A destructor, as the name suggests , is used to destroy the objects (free the
memory space) that have been created by constructor.Just like a constructor,
destructor is a member function whose name is same as class name but preceded
by a tilde(~) i.e we have to use a tilde before writing a class name to call a
destructor.
Now
for the betting understand of the concept l, let's talk about It's properties
to have a better insight.
Properties
-It
is called automatically whenever object is destroyed or removed from the
memory.
-It
is used to perform any operation at the time of destruction of any object.
-It
is called as per LIFO(Stack) method.(IMP)
-It
cannot have parameters. Thus, it cannot be overloaded.
-It
can be virtual.
Now
let's take an example how the objects are released from the memory.
Suppose
we have a class whose name is Complex.
Complex c1,c2,c3;
Here
c1, c2, c3 are objects of Complex class. So, c3 will be destructed first from
the memory, then after c2 will be destructed and finally c1 will be destructed.
I
hope after reading this article, the topic of destructor will be clear but If
you still face some kind of doubt or have any query then you can contact us.
Thank
you.
