C++ | Inheritance | Question 1

#include<iostream>

using namespace std;
class Base1 {
 public:
     Base1()
     { cout << " Base1's constructor called" << endl;  }
};

class Base2 {
 public:
     Base2()
     { cout << "Base2's constructor called" << endl;  }
};

class Derived: public Base1, public Base2 {
   public:
     Derived()
     {  cout << "Derived's constructor called" << endl;  }
};

int main()
{
   Derived d;
   return 0;
}

(A) Compiler Dependent

(B) Base1′s constructor called
Base2′s constructor called
Derived’s constructor called
(C) Base2′s constructor called
Base1′s constructor called
Derived’s constructor called
(D) Compiler Error

Answer: (B)
Explanation: When a class inherits from multiple classes, constructors of base classes are called in the same order as they are specified in inheritance.
