Member Access and Inheritance
Member Access and Inheritance: Although a subclass includes all of the members of its superclass, but cannot access those members of the superclass that declare as private. Here the Example : // This program uses inheritance to extend Box. class Box { double width; double height; double depth; // construct clone of an object Box(Box ob) { // pass object to constructor width = ob.width; height = ob.height; depth = ob.depth; } // constructor used when all dimensions specified Box(double w, double h, double d) { width = w; height = h; depth = d; } // constructor used when no dimensions specified Box() { width = -1; // use -1 to indicate height = -1; // an uninitialized depth = -1; // box } // constructor used when cube is created...
