Const array in .hpp and .cpp file

Question

In my .hpp file I have

extern const double MY_CONST[44];

and in my .cpp file I have

const double MY_CONST[44];

and I get something like this:

error: uninitialized const 'MY_CONST' [-fpermissive]

Could you please tell me where the error is? Thanks

Remember that const object must be initialized. You can declare them extern, but you must assign them. You may like to do:

const double MY_CONST[44] ={0};

To default initialize them all to zero. But that doesn't mean anything, since they are const (and will always have value 0).
