Our task is to, for each letter of the (English) alphabet, write a program that prints the alphabet, in a language whose name starts with that letter.

Input: none

Output:

abcdefghijklmnopqrstuvwxyz

uppercase and trailing newline optional

Rules:

  • The scoring metric is the length of the programming language name, plus the length of the code. Hence, C will be assessed a "penalty" of 1, while GolfScript will be assessed a penalty of 10.
  • One language/implementation per answer. Multiple answers are encouraged.
  • The programming language should have existed prior to the writing of this post, on this eighteenth of April 2011.
  • If a programming language name's first letter is not an English letter, it should not be coerced into one. It will be treated as a separate letter (meaning less competition).
  • No answer will be accepted until every English letter has a solution.

Current rankings:

C is for Clojure - (39 or 53) + 7 = 46 or 60

No, it doesn't stand for C. In Clojure, all functions form closures, so I would argue this is a complete answer, in 39 bytes.

(doseq[c(range 97 123)](print(char c)))

But if you really want it with the main function, 53 bytes.

(defn -main[](doseq[c(range 97 123)](print(char c))))

But, this isn't a Clojuric way to solve this problem. Let's try something simpler (could be golfed for 4 bytes).

(print (apply str (map char (range 97 123))))

Much better, isn't it?

Mouse, 26 + 5 = 31

97a:(a.123<^a.&DUP !'1+a:)

Which outputs:

Note the lame way would be:

"abcdefghijklmnopqrstuvwxyz"

Which gets printed implicitly immediately (as string literals do, unfortunately), but it's 28 bytes.

J is for Java - score: 84 characters + 4 = 88

interface a{static void main(String[]A){for(char c=65;c<91;System.out.print(c++));}}

This prints ABCDEFGHIJKLMNOPQRSTUVWXYZ instead of abcdefghijklmnopqrstuvwxyz. If it's disallowed, one can simply set c to 97 (a) and loop until it reaches 123 ({) at the cost of one extra byte:

interface a{static void main(String[]A){for(char c=97;c<123;System.out.print(c++));}}

F is for Funge → 19 chars + 5 = 24

'\`#;1+::,"@9"+\`#@_;

Something that makes this unique is that it doesn't contain a single letter of the alphabet! Hence why I didn't shorten it by replacing "@9"+ with 'y. I'll take the points hit for it.

Try it with my interpreter here: BefungeSharp.
