The grade distribution on the last practice test was A:6, B:1, C:1, D:0, E:3. Six of you earned A's, and I believe you are ready to take the CPE during class next Monday. Chris Jones has agreed to proctor and has already found a place for you to test.

The rest of you will take another practice test during that time. Please keep studying the three practice tests you should now have in your possession, looking for the common themes among the questions you got wrong, and using that reflective analysis to know what to ask for help with during our review sessions.

Today we'll take a short break from test prep and use Appendix C: A development environment for unit testing to configure our computers for C++ development.

As part of this process we will be introduced to test-driven development and the doctest testing framework.

After we get setup we will use the rest of time available in class to pair up and work on the following programming project:

Forwards and Backwards

Pair with a classmate and use TDD to complete the following. Let's make three pairs from the six of you taking the CPE on Monday, since if you earn the certificate then (and I know you will!) you'll be done testing and ready to start writing programs next week.

Write a program that prompts the user to enter a sequence of integers on the command line, with each integer seperated by a space. Your program should then print out the numbers entered forwards and backwards.

Here is a sample run of the program:

Enter a sequence of numbers, separated by spaces and terminated with Enter:
1 11 42 8 2 29 12 7

Your numbers were:
1 11 42 8 2 29 12 7

Your numbers backwards are:
7 12 29 2 8 42 11 1
