C++ allows you to specify more than one definition for a function name or an operator in the same. Examples on Xiith are made easier to make a better or basic understanding. geeksforgeeks. Note: A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal). We declared Rectangle as a friend of Square so that Rectangle member functions could have access to the private member, Square::side. A parallelogram is a simple object in 2D space having two parallel sides. 48,using a printf statement. By using the length and width, this program finds the perimeter of a rectangle. First method named as 'setDim' takes length and breadth of rectangle as parameters and the second method named as 'getArea' returns the area of the rectangle. * A constructor that creates a rectangle with the specified width and height.
