Atm Simulator using C++ (With source Code)
Hello, coders. Welcome to the codewithrandom blog. In this article, we will learn how to create an Atm Simulator using C++ (With Source Code).
An ATM Simulator is a console based software based on the notion of handling cash transactions for a personal account. The user may handle financial transactions like as withdrawals, deposits, and balance inquiries. This ATM Simulator is a scaled-down version of a genuine ATM. This project has been written in C++ programming language.

What can an ATM simluator do?
In terms of the system’s characteristics, the user can withdraw the amount. The user must input the withdrew amount, and the system will provide a withdrawal receipt with the transactions and amount. The user only needs to input a sum in the deposit field, and the money entered will be deposited. Another function is balance inquiry, which allows the user to see his or her total remaining balance.
In general, the ATM simulators may be used to withdraw or deposit money, as well as to obtain account information such as the balance amount, etc. They are straightforward and simple to use, allowing users to conduct rapid self-service transactions.
Overview of the UI:
- The welcome screen –
Please INSERT your Card [Press ENTER to insert card]
- The logo is displayed –
************** WELCOME TO ***************
- After loading when the main menu for transaction is displayed –
MAIN MENU TRANSACTION
[ 1 ] Withdrawal
[ 2 ] Deposit
[ 3 ] Check Balance
[ 4 ] Funds Transfer
[ 5 ] Exit ATM

Enter your choice: “
The user will choose an option to perform the operation of their choice. User will then enter a values according to the prompts that will be displayed on the console to perform that operation.

Now let us understand the code:-
- We will start by writing the header of the code with the required libraries – iostream (input and output stream), iomanip (formatting), stdlib.h (memory management), string.h (string manipulation), conio.h (console input/output), time.h (time management).
- Now we will declare some functions which will be used to give logic to the project – void showMenu(); int mainMenuSelection(int); void welcomeScreen(); void receipt(); void showLogo(); double enterAmountScreen(double);.
- The main() function consists of the function calls depending upon how the user operates the simulator. We will initialize some variables in the main() function. It will start off by displaying the welcome screen and the will prompt the user to type their bank account number and Personal Identification Number(PIN) for authentication.
- The program then checks to see if the account number and PIN entered match the predefined settings. If the values do not match, an error notice is displayed and the user is prompted to try again. If the values are the same, the program will show the main menu and asks the user to choose an option.
- We will create a do\while loop which will first display the menu and get the user’s choice, the it will validate the menu selection. Now we will declare functions to choose in the main menu selection. We will use if-else control statements to select between the options.
- The following options will be displayed to the user to select from:
- Withdrawal
