How to find out next character alphabetically?

Question

How we can find out the next character of the entered one. For example, if I entered the character \"b\" then how do I get the answer \"c\"?

Answer 1

How about:

char first = 'c';
char nextChar = (char)((int) first + 1);

Answer 2

How does ä sort? In German (I think) it should sort after a, but in Swedish it should come after å, which in turn is after z. This is not a trivial question, unless you restrict yourself to English.

Answer 3

Try this :

public string GetNextAlphabetLetter(int indice) {
  return ((char)('A' + indice)).ToString();
}

Answer 4

Note that a char will implicitly cast to an int. Here's a simplified solution:

char incrementCharacter(char input)
{
    return (input == 'z'? 'a': (char)(input + 1));
}

Answer 5

This Change value useful for Excel application to find previous column

public static string PrevExecelColumn( string s)
    {
        s = s.ToUpper();
        char[] ac = s.ToCharArray();
        int ln = ac.Length;
        for (int i = ln - 1; i > -1; i--)
        {
            char c = ac[i];

            if (c == 'A')
            {
                ac[i] = 'Z';
                continue;
            }

            ac[i] = (char)(((int)ac[i]) - 1);
            break;

        }
        s = new string(ac);
        return s;
   }  

Answer 6

Try this:

char letter = 'c';

if (letter == 'z')
    nextChar = 'a';
else if (letter == 'Z')
    nextChar = 'A';

else
    nextChar = (char)(((int)letter) + 1);

This way you have no trouble when the char is the last of the alphabet.
