      1 # Isogram
      2 
      3 Determine if a word or phrase is an isogram.
      4 
      5 An isogram (also known as a "nonpattern word") is a word or phrase without a repeating letter, however spaces and hyphens are allowed to appear multiple times.
      6 
      7 Examples of isograms:
      8 
      9 - lumberjacks
     10 - background
     11 - downstream
     12 - six-year-old
     13 
     14 The word *isograms*, however, is not an isogram, because the s repeats.

     16 ## Getting Started
     17 
     18 Make sure you have read the "Guides" section of the
     19 [C track](https://exercism.io/my/tracks/c) on the Exercism site. This covers
     20 the basic information on setting up the development environment expected
     21 by the exercises.
     22 
     23 
     24 ## Passing the Tests
     25 
     26 Get the first test compiling, linking and passing by following the [three
     27 rules of test-driven development][3-tdd-rules].
     28 
     29 The included makefile can be used to create and run the tests using the `test`
     30 task.
     31 
     32     make test
     33 
     34 Create just the functions you need to satisfy any compiler errors and get the
     35 test to fail. Then write just enough code to get the test to pass. Once you've
     36 done that, move onto the next test.

     39 
     40 As you progress through the tests, take the time to refactor your
     41 implementation for readability and expressiveness and then go on to the next
     42 test.
     43 
     44 Try to use standard C99 facilities in preference to writing your own
     45 low-level algorithms or facilities by hand.
