Question

just wondering, how do you use global arrays of a structure’s?

For example:

int y = 0;
object objectArray [100];

typedef struct object{
    time_t objectTime;
    int objectNumber;
} object;

int main(void)
{
    while(1)
    {
        time_t time_now;
        time_now = time(NULL);

        object x = {time_now, objectNo}
        objectArray[y] = x;
        y++;

    }
}

This always throws an “error: array type has incomplete element type”, can anybody advise me of the problem and an appropriate solution?
Thanks

Answer 1

Move the definition of the struct to before your declaration of the array:

typedef struct object{
    time_t objectTime;
    int objectNumber;
} object;

object objectArray [100];

You’re getting that error because the compiler doesn’t know the size of object when it gets to the array declaration.
