    text
    copied!<p>I'm trying to redefine two member functions from their parent's definition.<br>I don't know if I have it right or not, but something in my code has errors attached and I can't find out what.<br></p> <p>some of the header:</p> <pre><code>class Account { public: Account(double); void creditBalance(double); void debitBalance(double); double getBalance() const; protected: double balance; }; class CheckingAccount : public Account { public: CheckingAccount(double, double); void feeCreditBalance(double); void feeDebitBalance(double); private: double fee = 10; }; </code></pre> <p>relevant cpp file part:</p> <pre><code>void Account::creditBalance(double plus) { if(plus &gt; 0) balance += plus; else cout &lt;&lt; "Cannot credit negative."; } void Account::debitBalance(double minus) { if(minus &lt;= balance) balance -= minus; else cout &lt;&lt; "Debit amount exceeded account balance."; } void CheckingAccount::feeCreditBalance(double plus) { if(plus &gt; 0){ balance += plus; balance -= fee; } else cout &lt;&lt; "Cannot credit negative."; } void CheckingAccount::feeDebitBalance(double minus) { if(minus &lt;= balance){ balance -= minus; balance -= fee; } else cout &lt;&lt; "Debit amount exceeded account balance."; } </code></pre> <p>UPDATE:</p> <p>I added this:</p> <pre><code>class Account { public: Account(double); virtual void creditBalance(double); virtual void debitBalance(double); double getBalance() const; protected: double balance; }; </code></pre> <p>Now I get error: virtual outside class declaration</p> <p>I could use an example of how to properly initialize fee correctly.</p> <p>EDIT 2:</p> <p>I have tried changing the constructor line to this:</p> <pre><code>CheckingAccount::CheckingAccount(double initBal, double phi) : Account(initBal), fee(phi) { if(initBal &lt; 0) initBal = 0; balance = initBal; cerr &lt;&lt; "Initial balance was invalid."; if(phi &lt; 0) phi = 0; fee = phi; } </code></pre> <p>not working, I'm going to work around with changing syntax on the fee(phi) part. I don't know if anyone will respond to this.</p>
