D言語を初めて書いてみた。挨拶します。

greeting.d

import std.stdio;

void main()
{
  writeln("Hello, world!");
  Person kawachi = new Person(16, "Shinichi Kawachi");
  kawachi.greeting();
}

class Person
{
  int age;
  string name;

  this(int age, string name)
  {
    this.age = age;
    this.name = name;
  }

  void greeting()
  {
    writefln("My name is %s, I am %d years old.", this.name, this.age);
  }
}
