Review of Pointers

Count counter; // create counter object
Count *counterPtr = &counter; // create pointer to counter
Count &counterRef = counter; // create reference to counter

cout << "Set x to 1 and print using the object's name: ";
counter.setX( 1 ); // set data member x to 1
counter.print(); // call member function print

cout << "Set x to 2 and print using a reference to an object: ";
counterRef.setX( 2 ); // set data member x to 2
counterRef.print(); // call member function print

cout << "Set x to 3 and print using a pointer to an object: ";
counterPtr->setX( 3 ); // set data member x to 3
counterPtr->print(); // call member function print
