    Question hit a wall

    I am writing a program that is supposed to read info from a file clock.txt that has the number of employees then a name and then payrate and then another name and payrate. I have a struct

    struct employee {
           char* first[MAX_LEN];
           char* last [MAX_LEN];
           double payperhr;
           double taxes;
           double hours_in_week;
    the information im suppose to read in is
    john slacker 5.15
    jane worker 10

    now i have

    void scanclock(struct employee a){
       int i;
       int week, employee_day;
       double minin,hrin;
       double minout,hrout;
       int num_employee;
       FILE* fp;
     fp = fopen("clock.txt", "r");
     fscanf(fp, "%d", num_employee);
     for(i=0; i<=num_employee; i++)
     fscanf(fp, "%s%s%d", &a.first[i], &a.last[i], &a.payperhr);
     fscanf(fp, "%d", &week);
     for(i=1; i<=week; i++)
          fscanf(fp, "%d", &employee_day);
          fscanf(fp, "lf%lf%lf%lf", &minin, &hrin, &minout, &hrout); 
    I wanted to see if this either looks ok... and does it seem like im going down the right path? a.payperhr does that need to be strcpy and.... and should i keep it in a function or possibly better to do this in int main?

    It's always good to do things in functions.
    The parameter struct employee a should be struct employee *a since it represents an array of employee structs.
    Your first for loop condition should be i < num_employee, otherwise it will read once more than you want.
    Your second fscanf format should be "%s%s%lf" since payperhr is a double not an int.
    As for the other data you're reading, you haven't shown that in the data you posted.

    ahh ok thanks.. does any one know what would the basic format of sending a structure though a fucntion be? kinda as in the case above but not really important more for just trying to see another example.
