Inheritance - General Questions

Which type of inheritance has one derived class with several base classes?

What will be the output of the program?

#include <iostream>
using namespace std;
class A {
public:
    A() { cout << "A"; }
    ~A() { cout << "~A"; }
};
class B : public A {
public:
    B() { cout << "B"; }
    ~B() { cout << "~B"; }
};
int main() {
    { B b; }
    cout << endl;
    return 0;
}

With public inheritance, public members of the base class become:

What will be the output of the program?

#include <iostream>
using namespace std;
class A { public: A(int v) { cout << v; } };
class B : public A { public: B() : A(7) { cout << 8; } };
int main() {
    B b;
    cout << endl;
    return 0;
}

What will be the output of the program?

#include <iostream>
using namespace std;
class A { public: A() { cout << "A"; } };
class B { public: B() { cout << "B"; } };
class C : public B, public A { public: C() { cout << "C"; } };
int main() { C c; return 0; }
