variable 

お題

受け取った引数ARGV[0]をnameという変数(variable)に代入してそれを打ち出すcodeを書け.

> ruby name_variable.rb
Ruby

Rubyでの変数

rubyの変数は型宣言の必要性がなく,文脈に合わせて適当に型が定められます.イコールで代入されます.

name = 'Rudy'

method

お題

> ruby hello_method.rb Rudy
Hell Rudy.

と返すhello methodを作りなさい.

解説

Rubyではfunctionやprocedureなどのまとまりはmethodを定義(definition)することになります.methodは0個以上の引数(argument)を取ることができます.

def hello name
  puts "Hello #{name}."
end

name =ARGV[0]
hello(name)
