Simple ATM Machine Codding in C++

Simple ATM Machine Codding in C++:-

Here is a Simple ATM Machine Coding in c++(Automated teller machine).The code is written in c++ language. Dev  is used to compile the code. The code carry out all the functions that all standard atm machines do

INSTRUCTIONS:

PIN CODE is "1111"

TASKS:-

 It performs following functions:-
1.To check Balance
2.To Withdraw
3.To Deposit
4.To Exit

CODING:-


#include <iostream>

#include <conio.h>

#include <string.h>
using namespace std;

int main ()
{
system("color F0");
    int deposit=0;
    double amount=5000;
    int withdraw= 0;
    int choice=0;
    int pin=0;

   int keypin = 1111;
    
    
    cout << "Enter your pin code: ";
    cin >> pin;
    
  
    
    if (pin==keypin)
    {
    cout << "\nyour Pin is Approved!\n";
        
    cout << "\n\t====================================";
    cout << "\n\n\n\t  **** Welcome to ATM MACHINE ****";

    cout << "\n\n\n\t====================================";
    cout << "\n\n";
        
        int balance=1;
        int withdraw=2;
        int deposit=3;
        int Exit=4;
      char c;
  
    do{

        cout << "\nEnter Number of your choice: "<<endl;
        cout<<"1. To Check Balance   "<<endl;
          cout<<"2. To Withdraw "<<endl;
            cout<<"3. To deposit "<<endl;
            cout<<"4. To exit "<<endl;
       
        cin >> choice;
        
        if (choice==1)
        {
            cout <<"\nYour current balance is: \n" << amount<<endl;
       cout<<"enter y if you want to continue.";
       cin>>c;
        }
        
        else if (choice==2)
        {
            cout << "\nEnter the amount you want to withdraw: ";
            cin >> withdraw;
            
            if (withdraw>amount)
            {
                cout << "\nYou don't have sufficient balance.\n";
            cout<<"enter y if you want to continue.";
       cin>>c;
            }
            
            else
            {
            amount=amount-withdraw;    
            cout << "\nYour current balance is: \n" << amount;
             cout<<"enter y if you want to continue.";
       cin>>c;
            }
        }
        
        else if (choice==3)
        {
            cout << "\nEnter the amount you want to deposit: ";
            cin >> deposit;
            
            amount=amount+deposit;
            
            cout << "\nYour current balance is: \n" << amount;
               cout<<"\nenter y if you want to continue.";
       cin>>c;
       
        }
        
        else if (choice==4)
        {
            cout << "\nTHANK YOU! FOR BANKING WITH US......!!!!";
        }
        
    }while(c=='y');
} //if


    else if (pin!=0)
    {
        cout << "\nInvalid pin!" << "\nPlease try again.";
    }
    
    return 0;
    getch();
