Are the elements in this numbered 1-4 or 0-3 as I am making modifications to similar things and wish to use number_range rather than number_bits for selecting the random strings.

Why does the compiler complain if I change 4 to 3 then. 4 elements would be 0,1,2,3, but putting 3 instead of 4 gives error: too many initializers for ‘const char* [3]’
};

Kind of confused with what is happening, because i have some arrays that have 5 elements but with them, const char* [4] the compiler likes.

You have 4 elements, I can see them.

As you say, they are 0, 1, 2, 3.

Total of 4, and thus you can have up to 4 initializers.
