#include<stdio.h>
unsigned long AMOUNT=51520,DEPOSIT,WITHDRAW;
int CHOICE,PIN,K,TRY=0;
char TRANSACTION=’Y';
void main()
{
clrscr();
while(PIN!= 4567)
{
printf(“\nENTER YOUR PIN NUMBER :”);
scanf(“%d”,&PIN);
if(PIN!=4567)
{
printf(“\nYOU HAVE ENTERED INVALID PIN NUMBER!!\n”);
TRY++;
if(TRY==3)
{

getch();
exit();
}
}
}
do
{
clrscr();
printf(“*****WELCOME TO XYZ BANK*****\n”);
printf(“1.CHECK BALANCE\n”);

}
else if(WITHDRAW>(AMOUNT-1000))

break;
case 3:

case 4:
