} contact;

typedef struct contact_array
{
    int size;
    contact *data;
} contact_array;

void print_contact(contact *to_print)
{
    printf("%s (%s) age %i\n", to_print->name.str, 
    to_print->email.str, to_print->age);
}

int main()
{
    int i;
    contact_array contacts = { 0, NULL };
    for(i = 0; i < contacts.size; i++)
    {
        print_contact(contacts.data[i]);
    }

    return 0;
}

我收到以下错误:
