Q. Which class constructor is called in the following C++ code?

#include<iostream>

using namespace std;

class A {
public:
A()
{ cout << " The constructor of class A is called." << endl; }
};

class B {
public:
B()
{ cout << " The constructor of class B is called." << endl; }
};

class C: public A, public B {
public:
C()
{ cout << " The constructor of class C is called." << endl; }
};

int main()
{
C c;
return 0;
}
