Question

I have to 2 constant arrays in header files, say

const TPair<char, char> array1[] =
{
    {'V', rV},      
    {'v', rv},
    {'H', rH},
    {'h', rg},
    {0, 0}
};

and array2 similar to array1.
Now I need a function that will choose one of these arrays and return pointer to appropriate array.
How should signature of this function look like? And what do I return: array1 or array1&?

Answer 1

typedefs make this kind of code much more readable:

typedef TPair<char, char> pair_of_chars;

Then, …

const pair_of_chars array1[] =
{
    // [...]
};

Your choosing function may look a bit like this:

const pair_of_chars* choose(int number)
{
    if (number == 1)
    {
        return array1;
    }
    return array2;
}
