Needing some help with two errors (C++)

Ive been up for a while coding and it is probably an easy mistake that im just overlooking from lack of sleep, but the problem happens with this segment of code.

do
{
    aWithIntAcct.enterAccountData();
    aWithIntAcct.getSavInfo();
    aWithIntAcct.getCheckingInfo();
    checkAcct.push_back(aWithIntAcct);
    cout << "Would you like to enter another Checking Account with interest? y or n ";
    cin >> quitChar;
}while(quitChar != QUIT);

it says that I have ambiguous access of 'enterAccountData' (Error C2385) This is contradictory to the other (Error C3861) identifier not found.

My Classes are inherited so im not sure why this inst working for me. Any suggestions?

REST OF CODE:

#include <iomanip>

{
    cout << "-";
}
};
template <class T>
void produceReport(int tableRows, string title, T acctType)
{
cout << tableRows << endl;
cout << title << endl;
cout << acctType;
};

class BankAccount

This inheritance hierarchy is (probably) incorrect. Right now it looks like this:

 BankAccount       BankAccount
      |                 |
SavingsAccount   CheckingAccount
      \                 /
      CheckingWithInterest

So, each CheckingWithInterest object actually has two BankAccount base class subobjects: one from its SavingsAccount base class subobject and one from its CheckingAccount base class subobject.

So, when you try to call a BankAccount member function on a CheckingWithInterest object, e.g.,

CheckingWithInterest account;
account.enterAccountData();

the compiler doesn't know whether you mean the enterAccountData() from the BankAccount that is part of the SavingsAccount base class or you mean the enterAccountData() from the BankAccount that is part of the CheckingAccount base class.

I'm not sure what, exactly, your requirements are, but if you only want to have a single BankAccount base class subobject, you probably need to use virtual inheritance when you derive CheckingAccount and SavingsAccount from BankAccount, so that the BankAccount subobject is shared between them when they are composed in CheckingWithInterest:

class BankAccount
class SavingsAccount : public virtual BankAccount
class CheckingAccount : public virtual BankAccount
class CheckingWithInterest : public SavingsAccount, public CheckingAccount

If you really do want there to be two BankAccount base class subobjects, then when you call enterAccountData(), you need to qualify on which base class subobject you want to call the member function:

account.CheckingAccount::enterAccountData();
