Landon Curt Noll f64f244ba6 update due to recent commits
The largest change was due to modifying `ioccc.css`
that resulted in all year and entry tarballs being modified.

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.
