我想知道如何打印出这个巨大的圆形缓冲区。前 3 个块是结构，而 while 循环在 main 中，这只是我的代码的一部分。我现在不关注格式或输出。这只是我应该得到的一个想法。这条线是我关注的地方：
// 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]);
我的输入是：
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
我的输出应该是：
患者 ID = 5 的读数为： 温度： 08:00:10: 98.6 心率： 08:00:00:60 08:05:24:61 08:07:21:58 收缩压 舒张压 呼吸频率 08:00:11:15
