Ruby カロリー計算 アウトプット

Posted at

自分用のアウトプットです。

食べた食品のカロリー計算をするプログラムをしました。

M = 食品の品数
N = 人数
food = 1gあたりのカロリー
eat = 何g食べたか
carolie = トータルカロリー

qiita.rb
M,N = gets.chomp.split(" ").map{|i| i.to_i}

food = []
i = 0
M.times do 
  i = (gets.to_f / 100)
  food.push(i)
end


eat = []

N.times do
  i = gets.chomp.split(" ").map{|i| i.to_i}
  eat.push(i)
end

i = 0
f = 0
total = []
count = N
count1 = M - 1
calorie = 0

while count > 0 do
  for s in 0..count1 do
    calorie += (food[i] * eat[f][s]).floor
    i = i + 1
  end
  total.push(calorie)
  calorie = 0
  i = 0
  f = f + 1
  count = count - 1
end


puts total

あまりfor文使い慣れていないのでその点今回使えたのはよかったですかね。
おそらく今回2次元配列を使えばもっと凝縮できた感がありましたが、うまくいきませんでした。。。
