Introduction to OOP Chapter 16: Overriding : next previous audio real text

Simulating Refinement with Replacement

In most languages the most important features of a refinement can be simulated, even if the language uses replacement.
void Parent::example (int a) {
    cout << "in parent code\n";

void Child::example (int a) {
    Parent::example(12); // do parent code
    cout << "in child code\n"; // then child code
Note that this is not quite the same as Beta, as here the child wraps around the parent, while in Beta the parent wraps around the child.
