Code: Select all

/*
***Automated Teller Machine with authentication routine***
*/
#include <iostream>
#include <cstdlib>
using namespace std;

int main()

{
    int password;
    double balance = 10000;
    double withdraw, deposit;
    int option,i,tries=3;
    for (i=0;i<=3;i++)
    {
        cout <<"Enter password: ";
        cin>>password;
        if (password==123456)
        {
        cout<<"korek!!!\n";
        break;
        }
        else
        {
            tries--;
            cout<<"\nWrong password. "<<tries<<" tries left.\n\n";
            if(tries==0)
            {
            exit(0);
            }
        }
    }




   cout<<"\n";
   cout<<"           ***MOGOL***\n";
   cout<<"*** Automated Teller Machine***"<<endl;
   cout<<"Choose a Transaction:\n";
   cout<<"\n";
   cout<<"[1] Inquire Balance \n";
   cout<<"[2] Withdraw \n";
   cout<<"[3] Deposit \n";
   cout<<"[4] Quit \n";
   cout<<"\n";
   cout<<"Enter Option:";
   cin>>option;

   switch(option)
   {
   case 1:
      cout<<"\n[[[BALANCE INQUIRY]]]\n";
      cout.setf(ios::fixed);
      cout.setf(ios::showpoint);
      cout.precision(2);
      cout<<"\n Your current balance is $"<<balance<<endl;
      break;
   case 2:
      cout<<"\n[[[WITHDRAW]]]\n";
      cout<<"Enter amount: $";
      cin>>withdraw;

      balance = balance - withdraw;

      cout.setf(ios::fixed);
      cout.setf(ios::showpoint);
      cout.precision(2);

      cout<<"You withdrew $"<<withdraw<<endl;
      cout<<"Your remaining balance is $"<<balance<<endl;
   break;
   case 3:
      cout<<"\n[[[DEPOSIT]]]\n";
      cout<<"Enter amount: $";
      cin>>deposit;

      balance = balance + deposit;

      cout.setf(ios::fixed);
      cout.setf(ios::showpoint);
      cout.precision(2);

      cout<<"You deposited $"<<deposit<<endl;
      cout<<"Your new balance is $"<<balance<<endl;
      break;
      case 4:
