Consider the following class definitions: class baseClass { public: void print() const; int getX() const; baseClass(int a = 0); protected: int x; }; class derivedClass: public baseClass { public: void print() const; int getResult() const; derivedClass(int a = 0, int b = 0); private: int y; }; Suppose the definitions of the member functions of these classes are as follows: void baseClass::print() const { cout << "In base: x = " << x << endl; } baseClass::baseClass(int a) { x = a; } int baseClass::getX() const { return x; } void derivedClass::print() const { cout << "In derived: x = " << x << ", y = " << y << "; x + y = " << x + y << endl; } int derivedClass::getResult() const { return x + y; } derivedClass::derivedClass(int a, int b) : baseClass(a) { y = b; } What is the output of the following function main? int main() { baseClass baseObject(7); derivedClass derivedObject(3, 8); baseObject.print(); derivedObject.print(); cout << "****" << baseObject.getX() << endl; cout << "" << derivedObject.getResult() << endl; return 0; }
