Accessing to enum values by '::' in C++

Question

I have class like following:

class Car  
{  
public:  
    Car();  
    // Some functions and members and enums  
    enum Color
    {
              


        

Answer 1

Name the enum inside the nested class (as example one):

class Car
{
public:
    struct Color
    {
        enum Type
        {
            Red,
            Blue,
            Black
        };
    };

    Color::Type getColor();
    void setColor(Color::Type);
};
