How do you declare arrays in a c++ header?

Question

This is related to some other questions, such as: this, and some of my other questions.

In this question, and others, we see we can declare and initialise string arrays

Answer 1

Use the keyword static and external initialization to make the array a static member of the class:

In the header file:

class DataProvider : public SomethingElse
{
    static const char* const mStringData[];

public:
    DataProvider();
    ~DataProvider();

    const char* const GetData()
    {
        int index = GetCurrentIndex(); //work out the index based on some other data
        return mStringData[index]; //error checking and what have you omitted
    }

};

In the .cpp file:

const char* const DataProvider::mStringData[] = {"Name1", "Name2", "Name3", ... "NameX"};
