After the program was compiled and run, it was incredible to print a long text that exceeded the length of the source code, and these strings did not even appear in the source code at all. I know that the C code can be very weird, and it seems that this program uses a lot of recursion; but I never thought that there is such absurd source code, it seems basically garbled. I just searched, this code is an award-winning work of IOCCC.
IOCCC stands for International Obfuscated C Code Contest. Whose C code is the most confusing and illegible.
This competition has been held for 17 years, and here are some award-winning works in recent years.
You can see more at http://www.au.ioccc.org/years.html, but many need to be compiled and run in a Linux environment. The more interesting ones that can run in the windows environment are already below.
We assume that your compiled file names are abc.exe.
