TAILIEUCHUNG - Object Oriented Programming (19)

CSC241: Object Oriented Programming. Lecture No 21. 1 Previous Lecture.•. Polymorphism Example program. – person class.•. Virtual destructor. – base class destructor is virtual, derived class. destructor also become virtual.•. Friend functions. – can access private member of a class. 2 Today’s Lecture.•. Friend function. – example program: Distance class. – Friend function for functional notation.•. Friend classes.•. static functions. 3 Distance Distance { Distance. private: Distance::operator +. int feet; float inches; ( Distance d2 ) const {. public: int f = feet + ;. Distance() : feet(0),. inches() float i = inches +. {} ;. Distance (float fltfeet) { if(i >= ) {. feet = fltfeet; i -= ;. inches = 12*(fltfeet-feet); } f++;. Distance(int ft, float in) : }. feet(ft), inches(in) { } When. returnsuch constructor.
