Chapter 9, Problem 1DE

Assume the following main module is in a program that includes the binarySearch function that was shown in this chapter. Why doesn't the pseudocode in the main module work?

// This program uses the binarySearch function to search for a

// name in the array. This program assumes the binarySearch

// function has already been defined.

Module main ()

Constant Integer SIZE = 5

Declare String names [SIZE] = "Zack", "James", "Pam",

  "Marc" , "Susan"

Declare String searchName

Declare Integer index

Display "Enter a name to search for."

Input searchName

Set index = binarySearch(names, searchName , SIZE)

If index != - 1 Then

Display searchName, "was found."

Else

Display searchName, "was NOT found."

End If

End Module
