How to Convert Every Letter in the Alphabet To an Integer - Objective-C

Question

I am trying to convert every letter in the alphabet to an integer like this

A = 1;
B = 2;
...
Z = 26;

I went through some forum questions but none of them worked well. Is there a way of doing this without Arrays?

what did the forum questions suggest and which parts didn't work? — wattson12, Jun 11 '14 at 16:10
Try something, if that fails think about the problem, the failure, search the docs and try again with the new knowledge. — zaph, Jun 11 '14 at 16:17

for lowercase letters you need to subtract 96 from its value. Like this:

int a = 'a' - 96; // 1

for uppercase ones subtract 64. Like this:

int A = 'A' - 64;// 1

This will work for any letter of English alphabet

What about `ç`, `Š` or `á`? – Cyrille Jun 11 '14 at 16:16
@Cyrille they don't belong to the English alphabet – Andrey Chernukha Jun 11 '14 at 16:17

Hence @Sulthan's question, "What is an alphabet for you?" Not everyone's mother tongue is English. – Cyrille Jun 11 '14 at 16:18
Heck, even the word "Alphabet" originates from the Greek alphabet (Alpha, Beta, ...) – Cyrille Jun 11 '14 at 16:19
but the questioner is obviously meaning the English alphabet, cause he gives example starting from A and B and ending with Z – Andrey Chernukha Jun 11 '14 at 16:20

@Cyrille but there are NO such letters in English alphabet – Andrey Chernukha Jun 11 '14 at 16:22
