Write a Rectangle class, the private data members are the length (len) and width (wid) of the rectangle, the parameterless constructor sets len and wid to 0, and the parameterized constructor sets the value of length (len) and width (wid). In addition, the class also includes common methods such as calculating the perimeter of the rectangle, calculating the area of the rectangle, obtaining the length value of the rectangle, obtaining the width value of the rectangle, and modifying the length and width values of the rectangle to the corresponding formal parameter values.
