この巨大な循環バッファをどのように出力するのだろうかと思っています。最初の 3 つのブロックは構造体であり、while ループはメインにあります。これは私のコードの一部にすぎません。私は今、フォーマットや出力に焦点を当てていません。これは、私が何を得るべきかという単なるアイデアです。この行は、私が焦点を当てている場所です:
// copies from and to destination of the string of the timestamp and the value.
strcpy(chart.buffer[asci].reading[chart.buffer[asci].end].timestamp,
current.field[1]);
私の入力は次のとおりです。
5, 08:00:00, 2, 60 5、08:00:01、5、15 5, 08:00:10, 1, 986 5, 08:05:24, 2, 61 5, 08:07:21, 2, 58 5、08:10:11、6、0
私の出力は次のようになります。
患者 ID = 5 の測定値は次のとおりです。 温度： 08:00:10: 98.6 心拍数： 08:00:00: 60 08:05:24:61 08:07:21:58 収縮期血圧 拡張期血圧 呼吸数 08:00:11:15
