alphabet

I am trying to create a function which will give me alphabet position when an index is passed. It will be same like how excel shows it's columns. A...Z, AA,AB.... I wrote the below function to get the results upto Z. It looks like static string GetColumnName(int index) { const int alphabetsCount = 26; if (index <= alphabetsCount) { int code = (index - 1) + (int)'A'; return char.ConvertFromUtf32(code); } return string.Empty; } This works fine until 'Z'. It return 'A' if I pass 1 and return 'B' if I pass 2 and so on. But, I am not able to figure out how will I get AA when I pass 27 to this

I'm 90% sure there is a built in function that does this. I need to find the position of a character in an alphabet. So the character "b" is position 1 (counting from 0), etc. Does anyone know what the function is called? Thanks in advance! EDIT: What i'm trying to do is to send all the characters X amount of "steps" back in the alpha bet, so if i have a string with "hi" it would be "gh" if i sent it back one step. There might be a better way of doing it, any tips? Senthil Kumaran It is called index . For e.g. >>> import string >>> string.lowercase.index('b') 1 >>> Note: in Python 3, string

First of all, this is not a duplicate of: Quickest way to enumerate the alphabet Because I need to get all the characters of the alphabet OF AN ARBITRARY (variable) LANGUAGE, and that in the correct ordering sequence. How can I do that without knowing the alphabet of every possible culture/language ? System.Gobalization.Cultureinfo for example has information on date format, and a sorting method, and codepage info. But not info on the alphabet itselfs. Forthermore 'A' to 'Z' ordering iterating won't do, because German for example has characters such as ÄÖÜ, which are after 'Z' in the codepage

I have an array of N elements (representing the N letters of a given alphabet), and each cell of the array holds an integer value, that integer value meaning the number of occurrences in a given text of that letter. Now I want to randomly choose a letter from all of the letters in the alphabet, based on his number of appearances with the given constraints: If the letter has a positive (nonzero) value, then it can be always chosen by the algorithm (with a bigger or smaller probability, of course). If a letter A has a higher value than a letter B, then it has to be more likely to be chosen by

Given any character from a to z, what is the most efficient way to get the next letter in the alphabet using PHP? The most efficient way of doing this in my opinion is to just increment the string variable. $str = 'a'; echo ++$str; // prints 'b' $str = 'z'; echo ++$str; // prints 'aa' As seen incrementing 'z' give 'aa' if you don't want this but instead want to reset to get an 'a' you can simply check the length of the resulting string and if its >1 reset it. $ch = 'a'; $next_ch = ++$ch; if (strlen($next_ch) > 1) { // if you go beyond z or Z reset to a or A $next_ch = $next_ch[0]; } It depends

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 "az". after that begins with "ba" up to "bz" and so on... Anybody know some solution? Thanks EDIT: I forgot that I give a char "a" to the function then the function must return b. if u give "bnc" then the function must return "bnd" Edit: Made it do exactly as the OP's latest edit wants This is the simplest solution, and tested: static void Main(string[] args) { Console.WriteLine(GetNextBase26("a")); Console.WriteLine

I want to iterate over the alphabet like so: foreach(char c in alphabet) { //do something with letter } Is an array of chars the best way to do this? (feels hacky) Edit: The metric is "least typing to implement whilst still being readable and robust" (Assumes ASCII, etc) for (char c = 'A'; c <= 'Z'; c++) { //do something with letter } Alternatively, you could split it out to a provider and use an iterator (if you're planning on supporting internationalisation): public class EnglishAlphabetProvider : IAlphabetProvider { public IEnumerable<char> GetAlphabet() { for (char c = 'A'; c <= 'Z'; c++)

Is there an easy way to generate an array containing the letters of the alphabet in C#? It's not too hard to do it by hand, but I was wondering if there was a built in way to do this. I don't think there is a built in way, but I think the easiest would be char[] alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".ToCharArray(); C# 3.0 : char[] az = Enumerable.Range('a', 'z' - 'a' + 1).Select(i => (Char)i).ToArray(); foreach (var c in az) { Console.WriteLine(c); } yes it does work even if the only overload of Enumerable.Range accepts int parameters ;-) for (char letter = 'A'; letter <= 'Z'; letter++) { Debug
