 ## Author's comments:

 Fuuko is a sea star generator.  Feed her some input through stdin to
 get lots of sea star patterns in stdout.
 
-    gcc -O3 -std=c90 fuuko.c -lm -o fuuko_c90
-    echo IOCCC | ./fuuko_c90 > output_c90.c
+```sh
+cc -O3 -std=c90 fuuko.c -lm -o fuuko_c90
+echo IOCCC | ./fuuko_c90 > output_c90.c
+```
 
 If you compile with a C99 compiler instead of C90, the sea stars will
 have eyes.
 
-    gcc -O3 -std=c99 fuuko.c -lm -o fuuko_c99
-    echo IOCCC | ./fuuko_c99 > output_c99.c
+```sh
+cc -O3 -std=c99 fuuko.c -lm -o fuuko_c99
+echo IOCCC | ./fuuko_c99 > output_c99.c
+```
 
 Don't like sea stars?  Use a C++98 compiler to get dango instead.
 
-    g++ -O3 -std=c++98 fuuko.c -lm -o fuuko_cpp98

+g++ -O3 -std=c++98 fuuko.c -lm -o fuuko_cpp98
+echo IOCCC | ./fuuko_cpp98 > output_cpp98.c
+```
 
 Don't like dango either?  Use a C++11 compiler to get just circles (or
 swiss cheese, if you prefer that).
 
-    g++ -O3 -std=c++11 fuuko.c -lm -o fuuko_cpp11
-    echo IOCCC | ./fuuko_cpp11 > output_cpp11.c
+```sh
+g++ -O3 -std=c++11 fuuko.c -lm -o fuuko_cpp11
+echo IOCCC | ./fuuko_cpp11 > output_cpp11.c

 Don't like any of these patterns?  Use a C11 compiler and there will be
 no extra patterns.
