Overloaded Functions
  • int max(int x, int y) {
  • return (x <= y) ? y : x;
  • }


  • char* max(char* s1, char* s2) {
  • return (strcmp(s1,s2) < 0) ? s2 : s1;
  • }


  • Point max(Point p1, Point p2) {
  • d1 = sqrt(p1.x() * p1.x() + p1.y() * p1.y());
  • d2 = sqrt(p2.x() * p2.x() + p2.y() * p2.y())
  • return (d1 <= d2) ? p2 : p1
  • }
