Passing An Array Of Structures To A Function

Hi everyone,

It seems my struggles with structures have continued. In my current program, I'm trying to pass an array of structures into a function. I've declared my structure in a separate header file using typedef to define a new type called 'flight'. But when I try to compile my program, I get the following error message:

"Syntax error before flight"

Here is my code for main(), my header file "defs.h", and my function "find_depart()", respectively:

------------------------------------------------------------------------------------------------------

Code:

---

#include "defs.h"

int main(int argc, char *argv[])
{

        int time, closest;

        puts("Enter a time in military hours and minutes:");
        scanf("%d", &time);

        flight schedule[] =  /*flight is a structure type*/
        {{800, 1016, "Jason Mackenzie"},
          {943, 1152, "Valerie Woods"},
          {1119, 1331, "Antonio Vasquez"},
          {1247, 1500, "Natalie McIver"},
          {1400, 1608, "Scott Curtis"},
          {1545, 1755, "Yvonne Vogelar"},
          {1900, 2120, "Mitch Matthews"},
          {2145, 2358, "Marcie Maddox"}};

        find_departure(time, flight schedule[]);

        return 0;
}

---

------------------------------------------------------------------------------------------------------

Code:

---

#include <stdio.h>
#include <string.h>
 
#define FLIGHTS 8
 
typedef struct
{
        int depart;
        int arrive;
        const char *attendant;
} flight;  /*flight is now a new structure type*/
 
int find_departure(int time, flight schedule[]);

---

------------------------------------------------------------------------------------------------------

Code:

---

/*function to search flight schedule for times closest to time put in by user*/

#include "defs.h"

int find_departure(int time, flight schedule[])
{
        int j = 0; /*counter to search schedule*/

        int closest = time - schedule.depart[0];
        /*initially, the closest flight time is the first departure*/

        int temp;
        /*used to compare each departure time with current closest flight time*/

        if (closest < 0)
        {
                closest *= -1;  /*set closest as absolute value if negative*/
        }

        while (j <= FLIGHTS)
        {
                temp = time - schedule.depart[j];

                if (temp < 0)
                {
                        temp *= -1;  /*temp is absolute value if negative*/
                }

                if (temp < closest)
                {
                        closest = schedule.depart[j];
                        /*current departure is now closest to user's input*/
                }

                j++; /*check next departure time*/
        }

        return closest;
}

If someone could please tell me what I could be doing wrong, I would greatly appreciate it--thanks!

schedule.depart[0]

should be

schedule[0].depart

Vart,

I made the change to my array subscripting and membership selection, but I'm still getting errors. I want to pass my array of structures into the function called in main ( ). Thanks.

Then just pass it:

Code:

---

find_departure(time, flight schedule);

---

Note that the array will be converted to a pointer to its first element when it is passed to find_departure().
