AdaでFizzbuzz

More than 1 year has passed since last update.

なぜにAda

初投稿Adaだったのにずっと手つけてなかったので。
色々文法試したかったので、無駄に長いコードになってるよ。

コード

ada_online_compiler

--GNAT 4.9.3

-- 使用するライブラリの宣言with Ada.Text_IO;
use Ada.Text_IO;
with Ada.Integer_Text_IO;

-- mainとなる関数名は何でもよい
procedure FizBuz is
   -- サブプロは宣言部に記載
   function ModFB(I: in Integer) return Integer is
      ret: Integer := 0;
   begin
      if I mod 3 = 0 and i mod 5 = 0 then
         ret := 3;
      elsif I mod 3 = 0 then
         ret := 2;
      elsif I mod 5 = 0 then
         ret := 1;
      end if;
      return ret;
   end ModFB;

   procedure FizzBuzz(I: in Integer) is
   begin
      -- パターン網羅出来てないとコンパイラが怒る。なかなかやるやん。
      case ModFB(I) is 
         when 3      => Put_Line("FizzBuzz");
         when 2      => Put_Line("Fizz");
         when 1      => Put_Line("Buzz");
         when Others => Ada.Integer_Text_IO.Put(I,1);
                        New_Line(1);
      end case;
   end FizzBuzz;
begin
   for I in Integer range 1 .. 100 loop
      FizzBuzz(I);
   end loop;
end FizBuz;

感想

なかなか読みやすいね。リファレンスは読みにくいけど。
このサイトがなければ即死だった

一番時間かかったのは、サブプロをどう定義するかで、悩みまくり。
このサイトを見つけるまでが長かった。

ClassとかGenericsとかもあるみたいなので、
そのあたりうまく使ってDomemo作ろうかしら。
