+# Bob
+
+Bob is a lackadaisical teenager. In conversation, his responses are very limited.
+
+Bob answers 'Sure.' if you ask him a question.
+
+He answers 'Whoa, chill out!' if you yell at him.
+
+He says 'Fine. Be that way!' if you address him without actually saying
+anything.
+
+He answers 'Whatever.' to anything else.
+
+## Instructions
+
+Run the test file, and fix each of the errors in turn. When you get the
+first test to pass, go to the first pending or skipped test, and make
+that pass as well. When all of the tests are passing, feel free to
+submit.
+
+Remember that passing code is just the first step. The goal is to work
+towards a solution that is as readable and expressive as you can make
+it.
+
+Please make your solution as general as possible. Good code doesn't just
+pass the test suite, it works with any input that fits the
+specification.
+
+Have fun!
+
+
+## Getting Started
+
+Make sure you have read the [getting started with C++](http://help.exercism.io/getting-started-with-cpp.html)
+page on the [exercism help site](http://help.exercism.io/).  This covers
+the basic information on setting up the development environment expected
+by the exercises.
+
+## Passing the Tests
+
+Get the first test compiling, linking and passing by following the [three
+rules of test-driven development](http://butunclebob.com/ArticleS.UncleBob.TheThreeRulesOfTdd).
+Create just enough structure by declaring namespaces, functions, classes,
+etc., to satisfy any compiler errors and get the test to fail.  Then write
+just enough code to get the test to pass.  Once you've done that,
+uncomment the next test by moving the following line past the next test.
+
+```C++
+#if defined(EXERCISM_RUN_ALL_TESTS)
+```
+
+This may result in compile errors as new constructs may be invoked that
+you haven't yet declared or defined.  Again, fix the compile errors minimally
+to get a failing test, then change the code minimally to pass the test,
+refactor your implementation for readability and expressiveness and then
+go on to the next test.
+
+Try to use standard C++11 facilities in preference to writing your own
+low-level algorithms or facilities by hand.  [CppReference](http://en.cppreference.com/)
+is a wiki reference to the C++ language and standard library.  If you
+are new to C++, but have programmed in C, beware of
+[C traps and pitfalls](http://www.slideshare.net/LegalizeAdulthood/c-traps-and-pitfalls-for-c-programmers).
