Re: How to create an implementation for the overloaded << operator
I made some changes from the last post I made. The problem I am having was when I entered the account number for some reason they don't output the list of the account number I entered. I managed to output the first entry I entered but I can't output the entire list. But it list the total number of entry. I tried to debbug. I don't know where to start or how to fix them. Any idea? Please help
Here is the entire program:
bankAccount.cpp
#include <iostream>
#include <string>
#include "bankAccount.h"
#include "bankList.h"
using namespace std;
int main ()
{
bankList myList;
bankAccount myAcct;
int inputNum = 0, num = 0;
int acctSize = 5;
int mySize;
string keyEnter = "";
if (myList.empty())
{
cout << "Empty List: \n" << myList << endl;
}
mySize = myList.getCapacity();
cout << "Account Size is: " << mySize << endl;
while (keyEnter != "quit")
{
cout << "Please enter an account number (to stop enter '1010'): ";
cin >> inputNum[num];
if (inputNum == 1010)
{
keyEnter = "quit";
}
else
{
myAcct.setAcctNum(inputNum);
myList.insert(myAcct, num);
num++;
}
}
cout << "List are: " << myList << endl;
mySize = myList.getCapacity();
cout << "Account Size is: " << mySize << endl;
}
