    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:
    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; 
    }
    
    A fragment of the data i am trying to read is :
