Difference Between Constructor and Destructor

In this post, we will understand the difference between constructor and destructor.

Constructor

It helps allocate memory to an object.
It can take arguments.
It is called automatically when an object is created.
It allows an object to initialize a value before it is used.
They are called in the successive order of their creation.
There can be multiple constructors in a single class.
The copy constructor allows the constructor to declare and initialize an object from another object.
It can be overloaded.

class_name( arguments if any )
{
};

It deallocates the memory of an object.
It doesn’t take any argument.
It is called automatically when the block is exited or when the program terminates.
They allow objects to execute code when it is being destroyed.
They are called in the reverse order of their creation.
There is a single destructor in a class.
Destructor can’t be overloaded.

~ class_name( no arguments )
{
};
