Re: initialization failure

Hi,

------------code--------------------------------------
#include<iostream>
using namespace std;

class B{
        int y;
public:
        B(int b=3):y(b){}
        int getInt(){
                return y;
        }

};

class A{
        int x;
public:
        A(const int &x_){ //Line 1
                x=x_;
        }
        A(B *b){
                A(b->getInt()); //Line =

        }
        int getInt(){
                return x;
        }

};

int main(){
        B *b = new B;
        A *a = new A(b);
        cout<<a->getInt()<<endl;}

---------------------------------------------------------
I expected that in line 2, "b->getInt()" is 3, and by calling
construction function of Line 1, the printed result should be 2;

But it's 0, can anyone tell me the reason? Thanks in advance.
