Programming Project: Developing ATM Software ✓ Solved

Programming Project you Will Be Developing Atm Software

You will be developing “ATM Software” for MyBank. This ATM software will be accepting deposits and can make withdraws. The ATM is PIN code protected. You will be developing a program to ensure that unauthorized users cannot get into the system. Your program will check if the entered PIN CODE is in the prerecorded data file.

Your source code must be saved as a C++ file, and the document name must be: LastName_ATM.CPP. The source code file must contain a file header formatted as specified below. The header information must be complete and accurate. The source code file should use self-documenting code and additional comments (as required) to improve code readability.

Paper For Above Instructions

The development of ATM (Automated Teller Machine) software represents a significant step towards modernizing banking practices, specifically for MyBank. This ATM software is designed to enhance the banking experience by allowing customers to perform basic banking transactions such as deposits and withdrawals in a secure environment. This paper will detail the essential components of the ATM software, focusing on its functionalities, security features, and the implementation of the source code in C++.

Overview of ATM Software Functionality

The primary function of the ATM software is to facilitate the deposit and withdrawal of funds. It provides a user-friendly interface that customers can interact with while ensuring that their transactions are processed securely. By utilizing a PIN code to protect access to the system, the software will enhance security and prevent unauthorized access to user accounts.

Core Functionalities

1. User Authentication: The ATM software requires user authentication through a Personal Identification Number (PIN). When a user inserts their card into the ATM, they will be prompted to enter their PIN, which is verified against a stored dataset. If the PIN matches the corresponding account, access is granted; otherwise, the user is prompted to try again.

2. Deposits: Users can deposit money into their accounts. The ATM software will provide an option to enter the amount to be deposited, which should then be validated to ensure it is a positive number. After the transaction, the user will receive a receipt confirming the deposit.

3. Withdrawals: Users can also withdraw funds from their accounts, subject to sufficient balance verification. The system will allow users to enter the desired withdrawal amount and will check account balances to prevent overdraft situations. If there are sufficient funds, the amount will be dispensed and a receipt will be provided.

Security Features

Security is paramount in any banking application, particularly in an ATM system. Several measures are employed in the software, including:

  • PIN Code Protection: A 4-digit PIN code is utilized for user authentication. This ensures that only the account holder can access their funds.
  • Data File Verification: The software checks entered PINs against a secured data file, ensuring that all authentication processes are safe from unauthorized users.
  • Account Lockout: After a predefined number of failed attempts to enter the correct PIN, the ATM will lock the account to prevent further access attempts.

Implementation in C++

The source code for the ATM software will be written in C++. This choice of programming language allows for efficient memory management and system level programming, crucial for developing robust applications. Below is a basic overview of the code structure and the required file header format:

File Header Example:

/*


* File: LastName_ATM.CPP


* Author: [Your Name]


* Date: [Current Date]


* Description: ATM software for MyBank allowing deposits and withdrawals


*/

Sample Code Structure

The following is a simplified version of how the C++ code may be structured:

include 


include 


include 


using namespace std;


// Function prototypes


bool authenticateUser(string pin);


void depositFunds();


void withdrawFunds();


int main() {


string userPin;


cout 

cin >> userPin;


if (authenticateUser(userPin)) {


// Proceed with transactions


int choice;


cout 

cin >> choice;


if (choice == 1) {


depositFunds();


} else if (choice == 2) {


withdrawFunds();


}


} else {


cout 

}


return 0;


}


bool authenticateUser(string pin) {


// Check entered PIN against stored data


// Implement file reading and verification logic here


}


void depositFunds() {


// Implement deposit functionality


}


void withdrawFunds() {


// Implement withdrawal functionality


}

Conclusion

In conclusion, the development of ATM software for MyBank presents an invaluable service to customers, enabling secure and efficient banking transactions. Through user authentication, functionalities for deposits and withdrawals, and robust security measures, the software ensures that customers can manage their finances with confidence. Following the best practices in C++ programming, as outlined, will lead to a reliable and maintainable ATM system that serves the needs of MyBank and its customers effectively.
