	*
	Use a transformation constructor to convert the data of a specified type to an object of a class with a
	type conversion function to convert an object of a class to a specified type of data
	The general form of a type conversion function is:
	operator type name ()
	{The statement that
	implements the transformation
	}
	cannot specify a function type before the function name, and the function has no parameters
	The following example function name is: operator int
	
	*
	/Operator int ()
	{return
		m_inum;
	}
	

Private:
	int m_inum;
};

int _tmain (int argc, _tchar* argv[])
{

	test test;
	int m = test; This can be compiled through, if there is no type conversion function, the compilation error here, because the class type can not assign value to the int, once we define the
	//type conversion function, it will implicitly call


	int i;
	cin>>i;
	return 0;
}

Conversion constructors enable you to convert data of a specified type to an object of the class

You can convert an object of a class to a specified type of data by using a type conversion function

The general form of a type conversion function is:

operator type name ()

{The statement that implements the transformation}

Function type cannot be specified before function name, function has no arguments
