you were almost there. Why not compile it and find out?

--------------------  experiment.cpp -----------------------

#include <iostream>

using namespace std;

class A
{
  public:
    A(){x=5; cout << "constructing A" << endl;}
    int x;
};


class B:public A
{
  public:
    B(){y=7; cout << "constructing B" << endl;}
    int y;
};




int main() {
 cout << "in main" << endl;
 A * ob;
 cout << "creating a new B" << endl;
 ob = new B();
 cout << "leaving main" << endl;
 return 0;
}
