What happens when you attempt to compile and run the following code?

#include <iostream>
#include <string>
using namespace std;

const int size = 3;
class A {
public:
string name;
A() { name = "Bob";}
A(string s) { name = s;}
A(A &a) { name = a.name;}
};
class B : public A {
public:

int *tab;
B() { tab = new int[size]; for (int i=0; i<size; i++) tab[i]=1;} B(string s) : A(s) { tab = new int[size]; for (int i=0; i<size; i++) tab[i]=1;} ~B() { delete tab; }
void Print() {
for (int i=0; i<size; i++) cout << tab[i];
cout << name;
}
};
int main () {
B b1("Alan");
B b2;
b1.tab[0]=0;
b1.Print(); b2.Print();
return 0;
}
