Banking Management System Using C++ With Source Code

Introduction :

Language & Interface:

Language: C++
Interface: Console-based

Welcome to this comprehensive guide on a console-based banking system developed in C++. This application manages various banking functionalities, including account management, deposits, withdrawals, updates, and account deletion. Designed with object- oriented principles, it includes classes for users, accounts, and their specific types, such as Savings and Checking accounts.

Required Modules or Packages :

C++ Standard Library: For input/output operations, file handling, and time
SQLite ORM (for database management): (Optional) If you decide to integrate database support.

How to Run the Code :

Set Up Your Environment: Ensure you have a C++ compiler installed (e.g., g++, clang++) and an IDE or text editor of your choice (e.g., VSCode, NetBeans).
Compile the Code: Use a command like g++ -o banking_system cpp to compile your application.
Run the Executable: Execute the compiled binary with ./banking_system on Unix- based systems or banking_system.exe on Windows.

Code Explanation :

The banking system is structured using several classes, each with distinct responsibilities. Below is a detailed explanation of each component of the code:

User Class:

The User class is an abstract base class representing a general user in the system. It provides common functionalities for all users, including login and password management.

				
					class User { protected:
std::string username; std::string password;

public:
User(const std::string&amp; user, const std::string&amp; pass) : username(user), password(pass) {}


virtual bool login(const std::string&amp; pass) { return password == pass;
}


virtual void changePassword(const std::string&amp; newPass) {
password = newPass;
}


virtual ~User() {}
};

Attributes:

- username: Stores the
- password: Stores the

Methods:

- login(): Checks if the provided password matches the stored
- changePassword(): Updates the user’s

Customer Class: The Customer class inherits from User and adds functionality specific to customer operations.

				
					class Customer : public User { public:
Customer(const std::string&amp; user, const std::string&amp; pass) : User(user, pass) {}


void viewAccountDetails() {
// Implementation for viewing account details
}
};

Methods: viewAccountDetails(): Displays customer account (Implementation needed)

Admin Class: The Admin class, also derived from User, provides functionalities for managing customer accounts and other administrative tasks.

				
					class Admin : public User {
public:
Admin(const std::string&amp; user, const std::string&amp; pass) : User(user, pass) {}


void manageAccounts() {
// Implementation for managing customer accounts
}
};

Methods:

manageAccounts(): Allows the admin to add, remove, or modify customer accounts. (Implementation needed)

Account Class:

The Account class is an abstract base class representing a general bank account. It includes common attributes and methods for account management.

				
					class Account { protected:
std::string accountNumber; double balance;

public:
Account(const std::string&amp; accNum, double initialBalance) : accountNumber(accNum), balance(initialBalance) {}


virtual void deposit(double amount) { balance += amount;
}


virtual bool withdraw(double amount) { if (amount &lt;= balance) {
balance -= amount;
return true;
}
return false;
}


virtual ~Account() {}
};

Attributes:

- accountNumber: Unique identifier for the
- balance: Current balance of the

Methods:

- deposit(): Adds funds to the
- withdraw(): Removes funds from the account if sufficient balance.

SavingsAccount Class:

SavingsAccount is a derived class from Account that represents a savings account with specific features.

				
					class SavingsAccount : public Account { public:
SavingsAccount(const std::string&amp; accNum, double initialBalance) : Account(accNum, initialBalance) {}


void applyInterest(double rate) { balance += balance * rate;
}
};

Methods: applyInterest(): Applies interest to the account balance based on a given

CheckingAccount Class:

CheckingAccount is another derived class from Account, representing a checking account with its own features.

				
					class CheckingAccount : public Account { public:
CheckingAccount(const std::string&amp; accNum, double initialBalance) : Account(accNum, initialBalance) {}


// Additional methods specific to checking accounts can be added here
};

Methods: You can add additional methods specific to checking accounts, such as overdraft protection.

Additional Components:

Main Function:

The main() function ties everything together, allowing users to interact with the system.

				
					int main() {
// Create a customer and an admin
Customer cust("john_doe", "password123"); Admin admin("admin", "adminpass");

// Example usage cust.deposit(1000); cust.withdraw(500); admin.manageAccounts();

return 0;
}

Operations:
Creates instances of Customer and
Performs deposit and withdrawal
Allows the admin to manage
