	    What is a destructor?
	        --> It is an instance member function of a class hence can never be static
	        --> Destructor name is same as class name preceded by ~(pronounced tilde) symbol
	        --> No return type
	        --> No arguments, hence no overloading is possible
	        --> It is invoked implicitly when object is going to get destroyed

	    Use of destructor?
	        --> It should be defined to release resources allocated to an object

	    Some important points:
	        --> If a programmer does not explicitly create a destructor, compiler creates one.
	        --> But if the programmer creates one explicitly, the compiler does not create one.
