Review of Functions and Parameters

Answering the Question

You selected Answer B, shown below. This is not a correct solution to this part of the problem. The ampersand in front of a parameter indicates a reference parameter. However, only parameters in which answers are being sent back should be reference parameters. Go back and try again.


void CalculateCost(float & Price, int & NumPurchased, float & Cost)
   {
   Cost = Price * NumPurchased;
   if (Cost > 80.0)
      Cost = Cost - 5.0;
   }
