# Regarding individual entries:
#
# IOCCC winning entry code may not work on your system. Even with standards,
# conditions and build environments change, especially when it comes to more
# extreme code such you might find in an IOCCC winner. Moreover, what was
# allowed and liked in one IOCCC contest may no longer be liked/allowed in
# later IOCCC years.
#
# Corrections on winning author and fixing typos in remarks are VERY WELCOME.
#
# GitHub pull requests are welcome:
#
# If you have a patch that might make running an entry work in modern Unix-like
# environments, please create a GitHub pull request for the IOCCC judges to
# consider.
#
# Suggestions and corrections regarding Makefiles, winning author information,
# fixing typos in remarks, and code patches are welcome via opening a GitHub
# issue or better yet, by creating a GitHub pull request for the IOCCC judges
# to consider. To form a GitHub issue or GitHub pull, please visit:

## 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
echo IOCCC | ./fuuko_cpp98 > output_cpp98.c
```sh
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.
