Can you determine the relationship between the input and the resulting numeric output?
The program was not designed to process files with a certain octet value, what value is that?
This entry points out a minor flaw in the IOCCC rules that has been around since 1992. It processes a certain octet value in a way that differs from a strict reading of one of the official IOCCC rules. What is the rule and what is the octet value?
The main obfuscation is the way characters are recognized, which is done by matching the bit patterns. Minor obfuscations are:
Useless layout.
Useless variable names.
Recursive main()
instead of 2 loops (over input characters and over bits in
the character).
?:
and ||
instead of if statements.
