I Have Assign In C I Create Evrething But My Project Not Work Also

The task involves creating a C++ project that simulates bank account management functionalities, including creating accounts, displaying account information, making deposits and withdrawals, and updating account details. The provided code snippets include the main program logic, an account class header file, and part of the implementation. Despite the code’s structure, issues prevent the program from functioning correctly, and the goal is to develop a fully operational and debugged version that adheres to the intended design.

Paper For Above instruction

Bank account management systems serve as foundational projects in object-oriented programming, emphasizing class design, encapsulation, and functional operations. The provided code snippets indicate an attempt to implement such a system in C++. The core components include an Account class with attributes such as account ID, holder's name, and balance, alongside member functions managing account data and transactions. The main program demonstrates creating accounts, displaying information, modifying account details, and performing transactions such as deposits and withdrawals.

Analysis of the Existing Code and Issues

The provided Account.h file outlines essential data members and member functions, including constructors, accessors, mutators, and operational methods. However, several issues are apparent:

  • Inconsistent Constructor Initialization: The constructor with parameters initializes accountHolder to "no number" instead of the provided name.
  • Static Error: The declaration staticintaccountNumber = 100000; lacks a space, which should be static int accountNumber = 100000;.
  • Account ID Management: The getNextAccountNumber() method isn’t provided but is crucial for generating unique account numbers. It should increment the static accountNumber each time an account is created.
  • Implementation of Methods: The AccountClass code shows only partial implementation. The default constructor assigns accountID via getNextAccountNumber(), but the constructor with parameters assigns accountID correctly and sets accountHolder to the supplied name.
  • Accessing Methods: All methods should be correctly implemented and linked between header and source files. The main program calls methods like displayAccountInfo() and depositAmount(), which must be defined properly.

Steps to Correct and Complete the Implementation

  1. Fix static variable declaration and implement account number incrementation: declare the static accountNumber in the class scope, initialize at 100000, and create getNextAccountNumber() to increment this static variable each time.
  2. Implement constructors correctly: ensure that the parameterized constructor assigns accountHolder as per the parameter and initializes balance with the provided amount.
  3. Develop member functions: implement all declared functions, such as setting account holder, deposit and withdraw methods, ensuring they perform necessary checks (e.g., not allowing negative deposits or withdrawals exceeding balance).
  4. Create a source file (e.g., Account.cpp) where these methods are defined, following proper C++ conventions.
  5. Verify the main program: ensure it creates accounts properly, displays info, performs transactions, and updates data as expected.

Complete Implementation of the Account Class

Below is a comprehensive, corrected and functional implementation of the class based on the provided snippets and typical practices:

Account.h

ifndef ACCOUNT_H


define ACCOUNT_H


include 


include 


class Account {


public:


Account(); // default constructor


Account(std::string name, double amount); // parameterized constructor


int getAccountID() const; // accessor for account ID


std::string getAccountHolder() const; // accessor for account holder


double getBalance() const; // accessor for balance


void setAccountHolder(std::string name); // mutator for account holder


void setBalance(double amt); // mutator for balance


void depositAmount(double amt); // deposit method


void withdrawAmount(double amt); // withdraw method


void displayAccountInfo() const; // display info


private:


static int accountNumber; // static for generating unique IDs


int accountID;


std::string accountHolder;


double balance;


int getNextAccountNumber(); // helper for auto-increment account ID


};


endif

Account.cpp

include "Account.h"


// Initialize static member


int Account::accountNumber = 100000;


Account::Account() {


accountID = getNextAccountNumber();


accountHolder = "no name";


balance = 0.0;


}


Account::Account(std::string name, double amount) {


accountID = getNextAccountNumber();


accountHolder = name;


if (amount 

balance = 0; // Prevent negative initial balances


} else {


balance = amount;


}


}


int Account::getNextAccountNumber() {


return ++accountNumber;


}


int Account::getAccountID() const {


return accountID;


}


std::string Account::getAccountHolder() const {


return accountHolder;


}


double Account::getBalance() const {


return balance;


}


void Account::setAccountHolder(std::string name) {


accountHolder = name;


}


void Account::setBalance(double amt) {


if (amt >= 0)


balance = amt;


else


std::cout 

}


void Account::depositAmount(double amt) {


if (amt 

std::cout 

} else {


balance += amt;


}


}


void Account::withdrawAmount(double amt) {


if (amt 

std::cout 

} else if (amt > balance) {


std::cout 

} else {


balance -= amt;


}


}


void Account::displayAccountInfo() const {


std::cout 

}

Refined Main Program

The main function should correctly instantiate accounts, invoke methods, display information after each transaction, and handle edge cases like negative deposits or withdrawals.

include 


include "Account.h"


using namespace std;


int main() {


// Create accounts


Account acct01;


Account acct02("Harold M. Ferguson", 2000);


Account acct03("Elise Janet Simmons", 3500);


Account acct04("James Holder", 0);


cout 

acct01.displayAccountInfo();


acct02.displayAccountInfo();


acct03.displayAccountInfo();


acct04.displayAccountInfo();


// Modify account details


acct01.setAccountHolder("Mary A. Tarleton");


acct01.setBalance(542.39);


acct04.setAccountHolder("James Ellis Holder");


acct04.setBalance(1990.75);


cout 

acct01.displayAccountInfo();


acct02.displayAccountInfo();


acct03.displayAccountInfo();


acct04.displayAccountInfo();


// Deposits


acct01.depositAmount(455);


acct02.depositAmount(-19.95); // Should handle error


acct03.depositAmount(4365.27);


acct04.depositAmount(95.63);


cout 

acct01.displayAccountInfo();


acct02.displayAccountInfo();


acct03.displayAccountInfo();


acct04.displayAccountInfo();


// Withdrawals


acct01.withdrawAmount(37.39);


acct02.withdrawAmount(-475.25); // Should handle error


acct03.withdrawAmount(0.25);


acct04.withdrawAmount(50.00);


cout 

acct01.displayAccountInfo();


acct02.displayAccountInfo();


acct03.displayAccountInfo();


acct04.displayAccountInfo();


return 0;


}

Conclusion

In conclusion, the primary issues in the original code stemmed from incorrect static variable declaration, incomplete method implementations, and inconsistent constructor logic. By fixing these issues—correct declaration and initialization of static members, proper constructor implementation, and comprehensive method definitions—the program can perform its intended functions successfully. Proper testing with various transaction inputs ensures robustness against invalid operations like negative deposits and excess withdrawals. This project demonstrates fundamental object-oriented programming principles pertinent in banking systems, such as data encapsulation, unique account identification, and transactional integrity.
