prices[i] の形でしか prices を参照していないため、コードをシンプルにするため、 for (int price : prices) { でループを回したほうが良いと思います。

手癖でインデックスを使うfor文で回してしまっていたので今後使い分けます。

個人的には std::numeric_limits<int>::max() を使いたいです。

CのマクロではなくC++の標準ライブラリから使う機能を選んだほうが良さそうですね、以後気をつけます。

関数名と同じ変数名を使うと、名前を隠してしまい、思わぬバグを入れる場合があります。できれば異なる名前を付けたほうが良いと思います。
