Banking application storing account info in array
Feb 28, 2016 at 6:43pm UTC
Hello I've been working on a C++ banking application that should be able to hold more than one account with all the related field's. I have come across a few issues:
When creating an account only the most recent account is able to be searched for and displayed in display data. I know that an array is needed for this to be possible, I'm just not sure if implemented this correctly.
Thanks for the help. Any input is appreciated!
1 #include <stdlib.h>
#include <conio.h>
#include <iostream>
#include <string>
using namespace std;
class BankAccount{
double Balance = 0.0;
char ans;
public :struct Name{
char Last_Name[50];
char First_Name[50];
char Middle_Initial[5];
}Name;
public :struct Account{
char Type[1];
int Account_Number;
}Account;
public :
void CreateAccount();
void Withdraw();
void Deposit();
void Display();
void ShowInfo();
int Menu();
};
void BankAccount::CreateAccount(){
do
{
cout << "\nEnter account number: " ;
cin >> Account.Account_Number;
cout << "\nEnter the last name for the account: " ;
cin.ignore();
cin.getline(Name.Last_Name, 50);
cout << "\nEnter the first name for the account: " ;
cin.ignore();
cin.getline(Name.First_Name, 50);
cout << "\nEnter the Middle initial for the account: " ;
cin.ignore();
cin.getline(Name.Middle_Initial, 5);
cout << "\nEnter the type of account (C/S) : " ;

When displaying account info in Display or ShowInfo functions, the first letter of the first name and the middle initial wont show up.
Well that's because you're ignoring the first character of those strings in your input function.
Is there a reason you're using C-strings instead of std::string?
When creating an account only the most recent account is able to be searched for and displayed in display data. I know that an array is needed for this to be possible, I'm just not sure if implemented this correctly.
Looking at the fields in your class I suspect that you should be creating an array, or better yet a vector, of BankAccount.

I fixed the character issue by using strings but I'm still unable to hold multiple accounts. I know I need to use an array or better yet a vector but I'm not sure how i would implement them and allow the user to input the info for multiple accounts before returning to the main menu.

1#include <vector>
int main(int argc, char *argv){
std::vector<BankAccount> ob; // Create a vector of Bank accounts.
