What is the difference between constructor and destructor?

Constructor is used to initialize the class variable and create the object of the class.
Destructor is used to free the memory which was assigned to object while creating object.

ya its same as the answer but slight modification in destructor.
constructor initilises the object where as
destructor cleans up the object.

and we need to define destructor if u have pointers and DMA

Constructor is used to initialize variables. You can invoke a constructor becofe giving a call to any other method or program

Destructor is used to free the memomry by clearing up the variable values and setting them to NULL.

Characterstics of Constructor:
1)They should be declared in the public section.
2)They are invoked automatically when the objects are created.
3)They do not have return types,not even void and therefore,they cannot return values.
4)They cannot be inherited.through a derived class can call the base class constructor.
5)Like other C++ function,they can have default argument.
6)Constructor cannot be virtual.
7)We cannot refer to their address.
8)an object with a constructor connot be used as a member of a union.
9)They make implicit calls to the operators new and delete when memory allocation is required.

the specially linked attributes which are used in the under the same name, in which they have the access to the different member of the same.

Constructor is used to initialize the variables and destructor is used to free the memory of that variables.

constructor has the same name as the class use to initiate the objects. destructor has the tild and the same name as the class use to free the memory. Destructor is by default executed by garbage collector.
