Do your work in your Odin /3350/c folder.

Log on to Odin, then do this...

$ cd 3350
$ ./lab-start.sh
$ cd c
$ cp ../a/laba?.cpp exam12.cpp
$ cp ../a/Makefile .

1. Start with your lab-10 program.
2. Replace laba?.cpp with your program name from lab-10.

Files to be collected:
----------------------
3350/c/exam12.cpp
3350/c/data12.txt
3350/c/Makefile

What to do...

Write a unit-test in your program.


1. Create your own small dictionary file.
   About 10 to 20 words.


2. Create a second executable file using your Makefile.
   This executable will perform your unit test.


3. Use this preprocessor directive to isolate your unit test components.

   #ifdef UNIT_TEST

   Do not put #define UNIT_TEST in your program code.


4. Your Unit-test executable will get the file-name from the command-line.


5. Your program output should show the following:

   1. Known input words
   2. Expected output words
   3. Actual words output



Sample output format of your Unit Test...


$ ./utest

Program challenge number: N
Find all words that have no duplicate letters.

The data file for this test would look like this:
    
    hello     no
    exam      yes
    goodbye   no
    classroom no
    c++       no
    coding    yes
