Your visitor should work as you've written it.  Try adding some other kind of cash flow, such as FixedRateCoupon.

You 're welcome Ziegele,

1) No, because CashFlow is abstract and emplace_back relies on the existence of a constructor.

2) I am not familiar with the visitor pattern, but I suspect you could achieve this by removing all the visit overloads except the void visit( CashFlow & c ) one.

Then you modify the code inside as follows:

void visit( CashFlow & c ) {

  cashFlowSum += p->amount();

    if( SimpleCashFlow * p = dynamic_cast<CashFlow *>( &c ) ) {

	simpleCashFlowSum += p->amount();

    }

    else if( Redemption * p = dynamic_cast<Redemption *>( &c ) ) {

	redemptionSum += p->amount();

    }

    else if( AmortizingPayment * p = dynamic_cast<AmortizingPayment *>( &c ) ) {

	amortizingPaymentSum += p->amount();

    }

}

Let me know if this works

Thanks Yannis!

1 last question: is there a way to emplace_back a CashFlow shared_ptr? It
shows that it's purely virtual, which only serves as an interface:

Is there anyway of generating a non-zero report for "all other cash flows"
part?

Thanks,
