Thread: Problem regarding constructor inheritance

In this underlying code I have used parameterized constructor both in base class and in derived class but this is not working, I understand that I haven't passed any argument to the the constructor which has been inherited from A by B. How to get out of this mess?

Code:

#include<iostream>
using namespace std;
class A
    {
        int x;
        public:
        A(int x)
            {
                this->x=x;
                cout<<"I am in BASE CONSTRUCTOR "<<x<<endl;
            }
    };
class B:public A
    {
        int y;
        public:
        B(int y)
            {
                this->y=y;
                cout<<"I am in BASE CONSTRUCTOR "<<y<<endl;
            }
    };
int main()
    {
        A obj(123);
        B ob(345);
        return 0;
    }

Have you tried to use the constructor initialization list?

Code:

#include<iostream>
using namespace std;
class A
    {
        int x;
        public:
        A(int x) : x(x)
            {
                cout<<"I am in BASE CONSTRUCTOR "<<x<<endl;
            }
    };

class B:public A
    {
        int y;
        public:
        B(int y) : A(y), y(y)
            {

                cout<<"I am in BASE CONSTRUCTOR "<<y<<endl;
            }
    };

int main()
    {
        A obj(123);
        B ob(345);
        return 0;
    }

got it, but can we initialize PARAMATERIZED BASE constructor with NON-PARAMATERIZED DERIVED CLASS CONSTRUCTOR?
