c - 为什么我的编辑器无法识别我的 typedef 结构？ C

Question

新问题:我必须将文件中的数据读入结构数组，并且我的 scanf 函数出现错误。我真的不确定扫描结构的细节。这是我写的:

#include <stdio.h>
#include <string.h>
#include <math.h>

#define runnum 500
#define charnum 20

typedef struct {
        unsigned long bibnum;
        char lastname[charnum];
        char fistname[charnum];
        int grade;
        char team[charnum];
        char state[charnum];
        int time1;
        float time2;
    } runner_t;

int main(void)
{
    int i;
    FILE *ifile, *jfile;

    ifile = fopen("20121006.boys.txt", "r");
    jfile = fopen("20121006.girls.txt", "r");

    runner_t runarray[runnum]; 

    i = 0;

    while  (i < runnum)
        {
            scanf(ifile, "%ul", &runarray[i].bibnum);
            scanf(ifile, "%s", &runarray[i].lastname);
            scanf(ifile, "%s", &runarray[i].firstname);
            scanf(ifile, "%d", &runarray[i].grade);
            scanf(ifile, "%s", &runarray[i].team);
            scanf(ifile, "%s", &runarray[i].state);
            scanf(ifile, "%d", &runarray[i].time1);
            scanf(ifile, "%f", &runarray[i].time2);
        printf("%d %s %s %d %s %s %d:%f", runarray[i].bibnum, runarray[i].lastname, runarray[i].firstname, runarray[i].grade, runarray[i].team, runarray[i].state, runarray[i].time1, runarray[i].time2); 
        i++;
     }

#include <stdio.h>
#include <string.h>
#include <math.h>

#define RUNNUM 500
#define CHARNUM 20

typedef struct {
        unsigned long bibnum;
        char lastname[CHARNUM];
        char firstname[CHARNUM];
        int grade;
        char team[CHARNUM];
        char state[CHARNUM];
        int time1;
        float time2;
    } runner_t;

int main(void)
{
    int i;
    FILE *ifile, *jfile;

    ifile = fopen("20121006.boys.txt", "r");
    jfile = fopen("20121006.girls.txt", "r");

    runner_t runarray[RUNNUM];

    for (i=0; i < RUNNUM; i++)
        {
            fscanf(ifile, "%lu", &runarray[i].bibnum);
            fscanf(ifile, "%s", runarray[i].lastname);
            fscanf(ifile, "%s", runarray[i].firstname);
            fscanf(ifile, "%d", &runarray[i].grade);
            fscanf(ifile, "%s", runarray[i].team);
            fscanf(ifile, "%s", runarray[i].state);
            fscanf(ifile, "%d", &runarray[i].time1);
            fscanf(ifile, "%f", &runarray[i].time2);
        printf("%lu %s %s %d %s %s %d:%f"
        , runarray[i].bibnum
        , runarray[i].lastname, runarray[i].firstname
        , runarray[i].grade, runarray[i].team
        , runarray[i].state
        , runarray[i].time1, runarray[i].time2);

     }
return 0;
}

在此处编译。
