定义的结构体形式为
struct IRIS
{
\x05int Serial_number;
double parameter[4];
\x05int type;
}sample[30];
利用C语言的fread函数读取文件中每行数据到结构体数组中…………

用fread不方便,fscanf快
直接循环
fscanf(fp,"%d %lf %lf %lf %lf",
&sample[i].Serial_number,
&sample[i].parameter[0],
&sample[i].parameter[1],
&sample[i].parameter[2],
&sample[i].parameter[3]);
