Procedures

E-mail answers to the exercises below to ffggc@uaf.edu, using the subject “DA8”.

Your answers should consist of one file: nameid.h, from Exercise A. The file (or an archive file containing it) should be attached to your e-mail message.
Be sure to include your name in your e-mail.
I may not read your homework e-mail immediately. If you wish to discuss the assignment (or anything else) with me, send me a separate message with a different subject line.

Exercise A — Using an STL Table Implementation

Purpose

In this exercise, you will write a complete program that uses a C++ STL Table implementation.

Instructions

Write a C++ program that stores a collection of name/ID-number pairs, as described below. Be sure to follow the coding standards. All standards now apply!

When the program is run, a brief message is printed, and then pairs of names and ID numbers are entered by the user. Input is terminated with a blank line. Then the user may enter a series of names. The program checks the previously entered list of pairs. If the name is present, the corresponding ID number is printed; otherwise, a message is printed, indicating that the name was not found.

The source code for your program should be turned in as the single file “nameid.cpp”.

Here is a sample run:

CS 311 Spring 2008 - Assignment 8, Exercise A

Phase 1: Enter ID list entries (name & ID #).
         Blanks line ends input.

Enter name: Zephaniah Smith
Enter ID #: 23

Enter name: Hercules
Enter ID #: 6

Enter name: Hercules
Enter ID #: 0

Enter name:

Phase 2: Enter names.
         For each name, the corresponding ID will be printed,
            if the name is in the ID list.
         Blank line ends input.

Enter name: Gorgo
(Name not found)

Enter name: Hercules
ID # = 0

Enter name: Gorgo
(Name not found)

Enter name: Zephaniah
(Name not found)

Enter name: Zephaniah Smith
ID # = 23

Enter name:

Additional requirements:

Your program must store the list of names & ID numbers in an appropriate C++ Standard Library table implementation.
If two or more of the entered name/ID pairs have the same name, then only the last is stored.
Your program must properly handle names containing blanks. In particular, the above input must work essentially as shown.
Reasonable indications of what the program is for, and what the user is supposed to do, should be printed.

Hints:

You get to write your own main this time. But this means there is no test program, and so you have a greater responsibility for making sure your code works. Test your code. I strongly suggest you test your program with the above input! (And other input, too.)
But be careful when checking whether the name is already in the Table; again, the above input should work. Try your program with the above input!
Doing something like
```
cin >> value;
```
is not appropriate here, since this reads up to the next blank, not to the end of the line. Instead, you probably want to do something like
```
std::getline(cin, myString);
```
Lastly, your name is not “Smurgle Smorkoblix”.
