1354 [BA1003] The Rectangle class

Description

Design a class named Rectangle to represent a rectangle. The class contains:
Two double data field named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height.
A no-arg constructor that creates a default rectangle.
A constructor that creates a rectangle with the specified width and height.
The accessor and mutator functions for all the data fields. (getWidth, getHeight, setWidth, setHeight)
A function name getArea() that returns the area of this rectangle.
A function named getPerimeter() that returns the perimeter.

class Rectangle{  private:    double width, height;  public:    Rectangle() ;    Rectangle(double width, double height);    double getWidth();    double getHeight();    void setWidth(double width);    void setHeight(double height);    double getArea();    double getPerimeter();  };
