As D. Susman pointed out, this does not look like what you asked for,
perhaps you meant something like this:

class A {
virtual void foo();
};

class B : public A {
void foo() { bar(); }; // Call B::bar() in B::foo()
void bar();
};

int main() {
A* a = new B;
a->foo(); // This will call B::bar();
}
