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

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.
