Chapter 5, Problem 52PS

Complete the incremental implementation of Program 5-13. First write the code to implement the multiply function, then the divide function, and finally the print results function. The print results function should use a switch to determine which option was requested and then print the results in the format shown below.

$\text{number operator number}=\text{result}$

You may pattern the function after the print results in Chapter 4, but it will need extensive modification.
