Iterating through the Alphabet - C# a-caz

Question

I have a question about iterate through the Alphabet. I would like to have a loop that begins with \"a\" and ends with \"z\". After that, the loop begins \"aa\" and count to

Answer 1

This is like displaying an int, only using base 26 in stead of base 10. Try the following algorithm to find the nth entry of the array

q = n div 26;
r = n mod 26;
s = '';
while (q > 0 || r > 0) {
  s = alphabet[r] + s;
  q = q div 26;
  r = q mod 26;
}

Of course, if you want the first n entries, this is not the most efficient solution. In this case, try something like daniel's solution.
