Question 1

Assume a program contains a void function named calcNewPrice(). The function receives two double variables named oldPrice and newPrice. The function multiplies the contents of the oldPrice variable by 1.1, then stores the result in the newPrice variable. Which of the following can be used to call the calcNewPrice() function?

A. calcNewPrice(double oldPrice, double newPrice);

B.calcNewPrice(&oldPrice, newPrice);

C. calcNewPrice(oldPrice, &newPrice);

D. calcNewPrice(oldPrice, newPrice);

Question 2

Assume a program contains a void function named calcNewPrice(). The function receives two double variables named oldPrice and newPrice.

A. void calcNewPrice(double oldPrice, double newPrice);

B. void calcNewPrice(double &oldPrice, double newPrice);

C. void calcNewPrice (double oldPrice, double &newPrice);

D. void calcNewPrice(double &oldPrice, double &newPrice);
