what does this output? Derived *d = new Derived; delete d; and Base b; Derived d; given: class Base { public: Base() {std::cout << "Base Default Constructor" << std::endl;} Base(Base &base) {std::cout << "Base Copy Constructor" << std::endl;} virtual ~Base() {std::cout << "Base Destructor" << std::endl;} Base &operator=(const Base &base) {std::cout << "Base Overloaded Assignment" << std::endl; return *this;} };
class Derived : public Base { public: Derived() {std::cout << "Derived Default Constructor" << std::endl;} ~Derived() {std::cout << "Derived Destructor" << std::endl; };
Derived *d = new Derived; delete d;
Output of above code is

1. The copy constructor is used for one the following scenarios: I. Initialize one object from another of the same type. II. Copy an object to pass it as argument to a function. III. Copy an object to return it from a function. Read the following program and answer questions (20 points) #include <iostream> using namespace std; class Line public: int getLength( void); Line( int len // simple constructor Line( const Line &obj) 1/ copy constructor Line (); //...
C++ assignment help! The instructions are below, i included the main driver, i just need help with calling the functions in the main function This assignment will access your skills using C++ strings and dynamic arrays. After completing this assignment you will be able to do the following: (1) allocate memory dynamically, (2) implement a default constructor, (3) insert and remove an item from an unsorted dynamic array of strings, (4) use the string class member functions, (5) implement a...
