Line g(b) works as follow: - b has been previously created with the line B b(10), where it's member b.x was initialized with the parameter 10. -g(b) attempts to cast type B into type A by calling the operator A method in class B - this calls the A constructor with parameter b.x, which is 10, and initializes the resulting object's member i. - Then the method show() of the classA object is called, that displays its member i,which is now 10

line g(20) does the following: As 20 is passed as parameter to the function g, the integer g is casted into class A. So A constructor is called with parameter 20 to create object a, this initializes the member a.i to 20. Then the function A.show() prints i, which is 20.
