MIT AITI 2003 Lecture 8. Class And Object II. Objective. Represent a Point object The state includes point coordinates, a point label, etc. The “behavior” of a point : Finding the x, y properties, finding distance to another point, etc. We want to write our own data type called Point.

attributes. A class is a concept of something. Classes:. Vehicle 4 wheels, seats, engine, windows, color…… accelerate, start, stop, turn, lock,. methods. Truck …………. Sedan …………. Focus …………. Matrix …………. SUV …………. class:. Method & Attribute.

struct v.s. class. struct point { double x; double y; }; void main() { point p; double distance; p.x = 3.0; p.y = 4.0; distance = sqrt( p.x * p.x + p.y * p.y ); ....... }. class point { public: point(double x, double y); double xcoord();

To write a program is to:. Procedure v.s. Object. find a way to manipulate data -- We design procedures Procedure-Oriented Programming Statements + functions  programs. find data to manipulate – We choose data (object) Object-Oriented Programming Classes + Objects  programs

Constructors & Destructors. Controlling initialization & destruction. Operator Overloading. Most operators in C++ can be overloaded Two ways: Member function of user defined class Non-member "stand alone" function Any operator overloading has to involve a user-defined class object
