What is the output of the following C++ program?

#include #include

using namespace std;

class baseClass { public: void print() const; baseClass(string s = " ", int a = 0); //Postcondition: str = s; x = a;

protected: int x;

private: string str; };

class derivedClass: public baseClass { public: void print() const; derivedClass(string s = "", int a = 0, int b = 0); //Postcondition: str = s; x = a; y = b; private: int y; };

int main() { baseClass baseObject("This is the base class", 2); derivedClass derivedObject("DDDDDD", 3, 7);

baseObject.print(); derivedObject.print();

system("pause");

return 0; } void baseClass::print() const { cout << x << " " << str << endl; }

baseClass::baseClass(string s, int a) { str = s; x = a; }

void derivedClass::print() const { cout << "Derived class: " << y << endl; baseClass::print(); }

derivedClass::derivedClass(string s, int a, int b) : baseClass("Hello Base", a + b) { y = b; }
