ATM machine program in C++

In this article, we will build an ATM machine program in C++ that will have all the basic functionalities of an ATM. This project is good for someone having beginner to intermediate knowledge of C++ language. If you have a basic understanding of how arithmetic operations and functions work you will be able to easily follow this article.

Features

The user can enter his account number and PIN to use the ATM (default account number is 12345 and PIN is 55555
Users can withdraw cash and Deposit cash
Users can also view the current balance
Transfer cash from his account to another

Complete Code for ATM machine program in C++

We will use Code::Blocks IDE to develop this application. Open the Code::Blocks IDE and create a new project with the name atmsimulation, now in the main.cpp file paste the following code and run it.

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

void showMenu();
void welcomeScreen();
void receipt();
void showLogo();

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

int main()
{

int amount=10000;
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();
	}

Conclusion

In this article, we have built the ATM machine program in C++. This project provides all the features of an ATM system like withdrawing cash, depositing cash, checking the available amount, and transferring cash from one account to another. I hope this was easy to follow and that it helped you in some way.
