What C data type should I use for array indices? Should it be something like int or long or should it be unsigned int and/or unsigned long?

    If you might have more than 2**32 elements in your array, you need unsigned long, otherwise it would be overkill.

    array indices can be negative numbers as well. But you must know that the elements preceding the base element are a part of your array. So it depends on you whether to make the indices unsigned or not.
