BDO ATM Simulation in C++

This ATM Simulation was programmed in Dev C++ and I will teach you to create an automatic teller machine.

Step 1:

Lets start creating a file, so Open your Dev C++ Application then go to menu bar and click File, Click New > Source File.

Step 2:

Lets start coding!.
First, you need to include the following header files or the libraries.

#include <iostream>
#include <iomanip>
#include <stdlib.h>
#include <string>
#include <conio.h>
#include <time.h>
#include <string.h>
using namespace std;

Step 3:

Declare the user defined functions.

void showMenu();
int mainMenuSelection(int);
void welcomeScreen();
void receipt();
void showLogo();
void waiting();
double enterAmountScreen(double);

Step 4:

Create a functions with a delay time by seconds.

void waiting(unsigned int mseconds)
{
clock_t goal = mseconds + clock();
while (goal > clock());
}

Step 5:

and then the main method. In main method we are going to put the variable declarations, calling all the user defined functions, loops and conditions.. Just copy the code and paste it in your editor.

int main()
{
int choice, account;
string pin = "";
char ast;
cout << fixed << showpoint << setprecision(2);
welcomeScreen();
system("cls");
showLogo();
cout << "\n\n\t\t\t  Please type your Bank Account Number : ";
cin >> account;
cout << "\n\t\t\t  Please type Personal Identification Number(PIN) : ";
ast = _getch();
//cin >> pin;
while(ast!=13)
{
      pin.push_back(ast);
      cout << '*';
      ast = _getch();
}
 if (account!=301215 && pin!="301215")
 {
  cout << "\n\t\t\tInvalid Bank Account and PIN. Please try again!"<<endl;
getch();
   }  else
  {
//Create a do\while loop
do
{
//Display the menu and get the user's choice.
showMenu();
cin >> choice;
//Validate the menu selection.
while (choice < 1 || choice > 5)
{
cout << "\n\t\t\tPlease enter your choice 1, 2, 3, 4, or 5: ";
cin >> choice;
}
//Function to choose in the main menu selection
int withdrawChoice, depositChoice;

double money = 0.0;

 }

}

Step 6:

Create a function for Welcome Screen..

void welcomeScreen()
{
cout<<"\n\t\t\t _____________________________________________"
<<"\n\t\t\t|\t\t\t\t\t      |\n\t\t\t| \xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\t\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\t \xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2  |"

cin.get();
}

Step 7:

Create a function for Logo Screen..

void showLogo()
{
cout<<"\n\t\t\t + ************** WELCOME TO *************** + ";
cout<<"\n\t\t\t _____________________________________________"
<<"\n\t\t\t|\t\t\t\t\t      |\n\t\t\t| \xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\t\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\t \xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2  |"

   <<"\n\t\t\t|\t\t\t\t\t      |\n\t\t\t| =============== We Find Ways ===============|"; }

Step 8:

Function for menu.

void showMenu()
{
system("cls");
showLogo();
cout << endl <<" \t\t\t \xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2 MAIN MENU TRANSACTION \xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2";
cout << "\n\n\t\t\t [ 1 ] Withdrawal" << endl;
cout << "\t\t\t [ 2 ] Deposit" << endl;
cout << "\t\t\t [ 3 ] Check Balance" << endl;
cout << "\t\t\t [ 4 ] Funds Transfer" << endl;
cout << "\t\t\t [ 5 ] Exit ATM" << endl;
cout << "\t\t\t _____________________________________________"<<endl;
cout << "\t\t\t Enter your Transaction: ";
}

Step 9:

and the last is function for receipt.

void receipt()
{
system("cls");
showLogo();
char date[9];
char time[9];
_strdate(date);
_strtime(time);
cout << "\n\n\t\t\t\t\t PRINTING RECEIPT . . .\n";
waiting(3000);
system("cls");
showLogo();
cout << endl <<"\n\n\t\t\t|\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2 BANCO DE ORO \xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2\xB2|";
cout << "\n\t\t\t|\t\t\t\t\t      |"
<< "\n\t\t\t|\t     ATM TRANSACTION RECORD\t      |"
<< "\n\t\t\t|\t\t\t\t\t      |"
<< "\n\t\t\t|DATE:\t\t\t    "<<date<<"\t      |"
<< "\n\t\t\t|TIME:\t\t\t    "<<time<<"\t      |"
<< "\n\t\t\t|LOCATION:\t\t    MASBATE \t      |"
<< "\n\t\t\t|CARD NUM:\t\t    ************1215  |";
}

Enjoy and Happy Coding!
