pointer to array of structs

Nedenstående program udskriver alle 100 records.
Hvilken pointer type skal der bruges i den kommenterede linie??

Mvh smackers

===================
#include <stdio.h>

struct record {
  char name[30];
  char company[40];
  char address[50];
  int acctno;
  float balance;
}customer[100];

int main(void) {
   
  int i;
   
  struct record[] * ptr;  // virker ikke
  //struct customer * ptr
  //struct customer[] *ptr
   
  for (i = 0; i < 100; i++) {
      ptr = customer[i];
       
      printf("Name: %s, Company: %s, Address: %s\n", ptr->name, ptr->company, ptr->address);
      printf("Account no.: %d, Balance: %f\n", ptr->acctno, ptr->balance);
       
  }
 
  getchar();
  return 0;
}
