C++ Trouble Inputting Data into Private Vector (invalid use)

Question

I have a vector of class \"Account\". It\'s private to a class BankingSystem. Here\'s how I have them defined.

Account Class:

struct newAccount
{
string          


        

Answer 1

A static method does not have access to a class instance (no this) so inside of storeAccount and addAccount the member accounts_ does not exist.

FYI: nothing after a return statement will be executed so the line cout << "\n\t Account ID: " << a.accountID << " added successfully."; is rather useless in your current code.

Consider the following implementation for reference:

using namespace std;

class Account
{
private: // data members
    string firstName;
    string lastName;
    string accountPass;
    int accountID;
    float accountBalance;

public:
    // constructor that initializes members
    Account(int id, float bal, const string& fname, const string& lname, const string& pass)
        : accountID(id), accountBalance(bal), firstName(fname), lastName(lname), accountPass(pass) {}

}; //end of class Account

class BankingSystem
{
private: // data members
    int accountID;
    char fileName;
    vector accounts_;

public:
    void addAccount()
    {
        int ID;
        float balance;
        string pass, first, last;

        // prompt input, initialize values, etc

            // construct a new Account from values and add it to vector
        accounts_.push_back(Account(ID, balance, first, last, pass));
    }
    void storeAccount( const Account& newAccount )
    {
            // add an already initialized account
        accounts_.push_back(newAccount);
    }


}; // end of class BankingSystem
