+/*
+       Exercise 1-2. Experiment to find out what happens when printf's argument string
+       contains \c, where c is some character not listed above.
+       ===
+
+       When run together, no output is given. GCC gives many warnings, mostly stating
+       that the escape sequence is unknown. When I compile with only sequences that do
+       not draw warnings, I mostly get nothing. I believe further characters are
+       required in most sequences to make them meaningful.
