(Rectangle Class) need help to convert java to c++

1. (Rectangle Class) Create a class Rectangle. The class has attributes length and width, each
of which defaults to 1. It has methods that calculate the perimeter and the area of the rectangle. It
has set and get methods for both length and width. The set methods should verify that length and
width are each floating-point numbers larger than 0.0 and less than 20.0. Write a program to test
class Rectangle.
