はい、ここにはたくさんの方法があることを知っています。課題の一部です。このコードでは、合計が 100 以下の数値が入力された場合に「平均」出力が間違っていることを除いて、すべてが意図したとおりに機能します。例: 8,10,19 を入力し、0 を入力して出力を終了すると、count 3 sum 37 average 9.25.... 平均は 12.3333 になります。ここで、8、10、99 を入力すると、出力はカウント 3 合計 117 と平均 39 になり、これは正しいです。sum>100 で動作するのに、sum<=100 で動作しないのはなぜですか? 理解できません。私は何が欠けていますか?
