CSE 112-Lab #13 Object Oriented Exception Handling with Classes Pages 1003, 1004, and 1005 - Rectangle (Version 3) and Program 16-5 Modify the Circle Class from Lab #6 to add exception handling for negative radius inputs. Modify the main program to use a try/catch as shown below (Ref: page 1005). This will require creating a NegativeRadius class in the Circle class as shown on page 1002/3. This will also require creating an instance of the circle before trying to set the radius in main. Submit a text file with the modified main, and header file. int main() double radius 0; //To hold a radius Circle userCircle; // create an instance of the circle cout >radius; try userCircle.setRadius(radius); // Display the circle's data. cout >radius; try userCircle.setRadius(radius); // Display the circle's data. cout
