ATM trouble???

OK here is a piece of my program:

Code:

---

#include<stdio.h>
#include<math.h>
#define PIN 2424
#define TRUE 1

/* Function Prototypes */
void bank_logo(void);

void validate_pin(void);

int get_data(int money);

int get_balance(double balance, int bal_cash);

void fifties_twenties_tens(int tot_bal, int *fifty, int *twenty, int *ten);

int main(void)
{
double open_bal;
int cash;
int new_cash;
int money;
int balance_cash;
int fif;
int twen;
int tens;
int remaining_balance;

bank_logo();
validate_pin();

printf("Enter the opening balance of your account  $");
scanf("%lf", &open_bal);
 printf("Enter how much cash you need?  $");
scanf("%d", &cash);

 balance_cash = get_data(cash);
printf("\nThe amount you are withdrawing =  %d\n", balance_cash);

remaining_balance = get_balance(open_bal, balance_cash);
printf("Remaining Balance in your account = %d\n\n", remaining_balance); 
printf("    *** Take your cash as $$$ bills ***    \n\n");

fifties_twenties_tens(balance_cash, &fif, &twen, &tens);

printf(" %5d fifty %5d twenties and %5d tens\n\n", fif, twen, tens);
/*
printf(" %5d fifty %5d twenties and %5d tens", fifties_twenties_tens(balance_cash, &fif, &twen, &tens);
*/
return(0);
}


void validate_pin(void)
{
int id; /* input of user's PIN number */
int count;

for (count = 0; count < 3; ++count){

printf("Enter your 4-digit personal identification (PIN) >>  ");
scanf("%d", &id);
        if (id != PIN)
        printf("Sorry! Invalid PIN number !\n");
        else if (count == 3)
        printf("\nYour chances are up.  Better luck next time.\n\n");
        else
        break;
      }

}

What I want it to do in function validate_pin is if the user fails to enter the the PIN number after 3 tries, I want it to print Your chances are up. Better luck next time. And then end the program. But if the enter the PIN within 3 tries to continue with the program.

wrap it in a while statement, while(pin != correctpin && trys < 3)

I'm sorry I'm confused. What am I wrapping in a while statement??

Instead of using the for loop, use a while loop:

Code:

---

for (count = 0; count < 3; ++count){

printf("Enter your 4-digit personal identification (PIN) >>  ");
scanf("%d", &id);
        if (id != PIN)
        printf("Sorry! Invalid PIN number !\n");
        else if (count == 3)
        printf("\nYour chances are up.  Better luck next time.\n\n");
        else
        break;
      }

---

How about:

Code:

---

for(count = 0;count < 3;++count)
{
  ask for PIN
  if the entered PIN matches then break out of the loop with break statement
}
if count equals 3
  print they're out of turns and exit
