TAILIEUCHUNG - Lecture Object oriented programming - Lecture no 10

This section repeats the above two sections using a fmmal mathematical style. Its purpose is to illustrate the power of denotational semantics to enable the full specification of a programming languages type system and semantics. Since it is machine independent, this notation can be used by language and compiler designers as they define and implement new programming languages. | CSC241: Object Oriented Programming Lecture No 10 Previous Lecture Example : Distance class overloading ++ and – ++ add 1 in feet and 1 in inches, -- subtract 1 from feet and 1 from inches Prefix and postfix Overloading binary operator Distance operator + (Distance d2) { float i = inches + ; int f = feet + ; return Distance(f, i); } d3= d1+d2; Today’s Lecture Overloading binary operator +, – and = operator for ThreeD class < operator for distance class += operator for distance class Subscript operator [] for Safe array class Data conversion Overloading -, + and = binary Operators class ThreeD { int x, y, z; public: ThreeD() { x = y = z = 0; } ThreeD(int i, int j, int k) { x = i; y = j; z = k; } ThreeD operator+(ThreeD op2); ThreeD operator=(ThreeD op2); ThreeD operator-(ThreeD op2); void show() ; }; // Overload subtraction.
