Consider the following class definitions in a hypothetical Object Oriented language that supports inheritance and uses dynamic binding. The language should not be assumed to be either Java or C++, though the syntax is similar.Class P{ void f(int i) { print(i); }}Class Q subclass of P{ void f(int i) { print(2*i); }}Now consider the following program fragment:P x = new Q();Q y = new Q();P z = new Q();x.f(1); ((P)y).f(1); z.f(1); Here ((P)y) denotes a typecast of y to P. The output produced by executing the above program fragment will be(A) 1 2 1(B) 2 1 1(C) 2 1 2(D) 2 2 2 |
