c++ Function to return an enum?

So I have this namespace called paddleNS for the class called paddle, inside paddleNS I have an enum known as colour

namespace paddleNS
{
   enum COLOUR {WHITE = 0, RED = 1, PURPLE = 2, BLUE = 3, GREEN = 4, YELLOW = 5, ORANGE = 6};
}

class Paddle : public Entity
{
private:
    paddleNS::COLOUR colour;
public:
    void NextColour();
    void PreviousColour();
    void PaddleColour(paddleNS::COLOUR col) { colour = col; }
};

Now then, what I was wondering is how would I go about creating a function that will return what the colour currently is also is there an easier way to return it in text form instead of a value or am I better of just using a switch to figure out what the colour is?

Hey you can make your function in header that look like this:

enum COLOUR function();

and when you define a function:

enum Paddle::COLOUR Paddle::function(){
        // return some variable that hold enum of COLOUR
}

in main.cpp i enter code herethink you can manage it

Keep an array of strings where the indix in to this array of strings matches the enum value you are using.

So if you have: 

enum COLOUR {WHITE = 0, RED = 1, PURPLE = 2, BLUE = 3, GREEN = 4, YELLOW = 5, ORANGE = 6};

I would then have an array defined:

String colors[] = {white, red, purple, blue, green, yellow, orange}

Then when you have a function return an enum of this type you can just put it into your array and get the correct color in string format.

class Paddle : public Entity
{
  // ----

  const char* currentColour() const { 
switch(couleur)
{
 case WHITE:
   return "white";
   break;
//And so on
}
}
};

Just return the enum by value:

class Paddle : public Entity
{
  // as before...

  paddleNS::COLOUR currentColour() const { return colour; }
};
