Counting a string
in [Ruby]
|
From: Benedikt Müller on 26 Feb 2010 08:30 Hi I want to âcountâ a string. I don't know, how to express it better, because of that I'll try to explain it. I have a string, say 'a'. Now I want to increase it, so it would be 'b'. I increase it again, it would be 'c' and so on. Is there a method for this task? -- GruÃ, Benedikt

From: Benedikt Müller on 26 Feb 2010 08:37 thx Sorry I looked in ruby-doc in the String class but I didn't saw it so I thought that isn't in the standard lib. :( -- GruÃ, Benedikt
From: Benedikt Müller on 26 Feb 2010 09:46 Is there a possibility to say what chars can be in the string? I want to have upper chars and lower chars but i want to start with only one char. -- GruÃ, Benedikt
