I have to create this program in c++ but I have many problems when I try to create can you help me please.
Create a class rectangle. The clas has attributes length and width, each of which defaults to 1. It has members function that calculate the perimeter and the area of the Rectangle. It has set and get functions for both length and width. The set functions should verify that length and width are floating-point numbers larger than 0.0 and less than 20.0. Create a program to test the Rectangle class.
