    Hi i am quite new to C.Wanted help on a segmenation fault in the foll program >>
    Am simply trying to read file contents into variables defined in struct data
    Code:
    #include<stdio.h>
    int main()
    {
    const MAX = 1000;
    struct data
    {
    float *lat[MAX];
    float *lon[MAX];
    float *hc100[MAX];
    int day[MAX];
    int month[MAX];
    int year[MAX];
    int jd[MAX];
    int n[MAX];
    char *d[MAX];
    };
    int i;
    struct data data1;
    FILE* fp;
    
    fp = fopen("hc100-Ebox.par","rw");
    if(fp == NULL) 
    {
    printf("FILE DOESNT EXIST");
    goto l1;
    }
    
    while(!feof(fp)||i<MAX)
    {
    fscanf(fp,"%f %f %d %d %d %f %d %c %d",data1.lat[i],data1.lon[i],&data1.day[i],&data1.month[i],&data1.year[i],data1.hc100[i],&data1.jd[i],data1.d[i],&data1.n[i]);
    i++;
    }
    fclose(fp);
    l1:return 0;
    }
