ATM Machine System in C++

Here is a simple project on ATM(Automated teller machine).The code is written in c++ language. Visual studio is used to compile the code. The code carry out all the functions that all standard atm machines do. You can check amount present in your account, withdraw balance and deposit amount. In the code below there are four ATM card holders. Each card holder is assigned a pin code for their ATM cards and a password of their account. The card holders with their names, Pin code of card’s and password of account’s are listed below.
NAME PINCODE PASSWORD

ALI 1111 5555
SAJOO 2222 6666
IJAZ 3333 7777
TOUSEEF 4444 8888

Atm code compilation and running

When you run the project compiled code in visual studio ide or its exe file. A text message will pop up on the screen of the display “PLEASE ENTER THE PINCODE“. Now enter the pin code assigned to four users above. Pin code must be of the person in whose account you want to withdraw, deposit or print the balance receipt.

If the pin code is valid another message will be displayed on console “ENTER PASSWORD“. Enter the password of the person whose card pin code is previously entered. Entering wrong password will give you an error message and the system will ask you to please try again. If three times you entered a wrong password your card will be captured (System just displays a message on console that your card is captured).

Functions in c++ code

There are only two functions main() & printstar() in code. Main function is the core of whole the atm system. Every thing is present in the main code. Printstar is just printing *(Asterik). There is no big or complex logic in the code, only just use of simple if else statements.

Whole of the atm logic is implemented in the if else statements. If you go through the code you will find that all the users ALI, SAJOO, IJAZ and TOUSEEF are working on the same logic and there is no difference in there codes.

As i mentioned earlier the project is simple. You can make it perfect by introducing filing in it. Save the transactions of a person in a file, read the balance from there, deposit balance there. By filing you can make a perfect ATM system system. This code is just to give you an idea how to make atm machine.

So far the atm works on run time. Every record is lose when the application is closed. I would suggest to attach the atm system with a database. So that each and every record can be retrieved and assessed at later stages.

Exe file of the project is below. Check its working On-line.
