というような記述でMaeArrとUshiroArrが連結され、MaeArrの最終要素の後ろにUshiroArrの先頭要素が来るように連結されます。結果、RenketsuArrの配列が連結された結果の内容になります。MaeArrもUshiroArrはなくなりません。concatは英語のcon･catenate=連結から来ていると思います。 | というような記述でMaeArrとUshiroArrが連結され、MaeArrの最終要素の後ろにUshiroArrの先頭要素が来るように連結されます。結果、RenketsuArrの配列が連結された結果の内容になります。MaeArrもUshiroArrはなくなりません。concatは英語のcon･catenate=連結から来ていると思います。 | ||
