The commit a1c86c8a7a modified
the navigation bars to include "Original C", so all tarballs
had be update, sorry (tm Canada 🇨🇦). In particular:
The navigation bar for a winning entry now has a "_Original C_" link
(between the ✅ and the Inventory on the right hand side) so that one
may easily view the original C code that was submitted for IOCCC judging.
In addition, a number of other commits since that time
modified other winning entries.
Ran `make update` to perform the above.
To build:
make all
There is an alternate version that does something different
that can be used if your compiler is incapable of compiling X=g()... in
main(). It can be used for another purpose too.
To use:
./pjr
Alternate code:
Note that some compilers will be unable to compile the expression X=g()... in
main() due to lack of temporary stack space. One might want to try replacing
main() with:
main(){X=s().v().o().o().l().S().d().l().i().o().w().N();}
if this is a problem, which is what this alternate code is.
NOTE: it prints something else and it is what the author suggested one try as well.
Alternate build:
make alt
Alternate use:
./pjr.alt
Judges' remarks:
This program prints out a string. Can you figure out how it is done?
By use of pointers to functions returning a struct of pointers to functions!
NOTICE to those who wish for a greater challenge:
If you want a greater challenge, don't read any further: just try to understand the program via the source.
If you get stuck, come back and read below for additional hints and information.
What this entry does:
This program prints out the string:
the quick brown fox jumped over the lazy dog
Author's remarks:
It is simple to make the program print other strings. Each alphabetical character from a to z is printed out as its opposite:
a->z b->y c->x etc
To encode a new string input the string as it is meant to come out:
X=s().v().o().o().l().S().d().l().i().o().w().N();
Note: S() represents a space and N() a newline. This will now
produce...
hello world
By the way, there is actually a piece of code which is not used in the original program! I leave it as an intellectual exercise to the reader to find out what it is.
