Chapter 7, Problem 4P

The following code creates a small phone book. An array is used to store a list of names and another array is used to störe the phone numbers that go with each name. For example. Michael Myers’ phone number is 333-8000 and Ash Williams’ phone number is 333-2323. Write the function lookupName so the code properly looks up and returns the phone number for the input target name.

  int main ()

  {

  using namespace std;

  string names[] = {“Michael Myers”,

  “Ash Williams”,

     “Jack Torrance”,

     “Freddy Krueger”};

  string phoneNumbers[] = {“333–8000”, “333–2323”,

  “333–6150”, “339–7570”};

  string targetName, targetPhone;

  char c;

  do

  {

  cout << “Enter a name to find the ”

  << “corresponding phone number.”

  << endl;

  getline(cin, targetName);

  targetPhone = lookupName(targetName,

  names, phoneNumbers, 4);

  if (targetPhone.length() > 0)

  cout << “The number is: “

  << targetPhone << endl;

  else

  cout << “Name not found. ”

  << endl;

  cout << “Look up another name? (y/n)”

  << endl;

  cin > c;

  cin.ignore();

  } while (c == ‘y’);

  return 0;

  }
