    i got some enum error cant find solution

    i tried retype the program that draw circle from the book beginner to c++ in 3 weeks
    but i cant get it to work, i have check from my code and the books code but i cant find the error the kompilator keep coming back to enum here is the kods

    Code:
    #include <iostream>
    using namespace std;
    enum CHOICE { DrawRect = 1, GetArea, 3: GetPerim, 
    ChangeDimensions, Quit};
    
    // Deklaration av klassen Rectangel
    
    class Rectangle
    
    {
          public:
                 //kontruerare
                 Rectangle(int width, int height);
                 ~Rectangle();
                 
                 //atkomster metoder
                 int GetHeight() const { return itsHeight;}
                 int GetWidth() const { return itsWidth;}
                 int GetArea() const { return itsHeight * itsWidth;}
                 int GetPerim() const { return 2 * itsHeight + 2 * itsWidth;}
                 void SetSize(int newWidth, int newHeight);
                 
                 //div.metoder

    It looks like this:
    Code:
    enum CHOICE { DrawRect = 1, GetArea, 3: GetPerim, 
    ChangeDimensions, Quit};
    should be:
    Code:
    enum CHOICE {DrawRect = 1, GetArea, GetPerim, ChangeDimensions, Quit};

    Well enum is typed incorrectly. You would do it like this:
    Code:
    enum CHOICE { DrawRect = 1, GetArea = 2, GetPerim = 3, 
    ChangeDimensions = 4, Quit = 5};
    Also you might not need to give enum an identifier ("CHOICE") unless you intend to use it as a type.
