Compileert het onderstaande programma (motiveer uw antwoord)? Indien
ja: wat is de output. Indien neen: waarom niet? 

#include <iostream>

class A {
  public:
    A(int i): data(i) { std::cout << "A::A(" << i << ")" << std::endl; }
    A(const char* s): data(0) { std::cout << "A::A(" << s << ")" << std::endl; }
    ~A() { std::cout << "A::~A()" << std::endl; }
  private:
    int data;
};

class B: public A {
  public:
    B(const A& a): A(a) { std::cout << "B::B(const A& a)" << std::endl; }
    ~B() { std::cout << "B::~B()" << std::endl; }
};

int
main(int, char**) {
  B b0(1);
  B b1("abc");
}
