Added `bin/bin/tar-entry.sh` to build a compressed tarball for an entry. The compressed tarball is formed by gnu tar with options so that the same entry file content will always produce the same compressed tarball, byte for byte. As some files are missing from some entries, one should use the `-W` option as in: ```sh bin/tar-entry.sh -v 5 -W 2020/ferguson1 ``` Added `make form_entry_tarball` to the top level `Makefile` to build entry tarballs even when files are still missing. Added `make verify_entry_files` to verify that all entries have all of their files listed in their manifest, plus the top level ioccc.css and var.mk files. As file entry files are still missing (due to HTML files that need to be built), the overall `make quick_www` and `make www` do **NOT** (yet) exit when the `make verify_entry_files` fails. Improved `bin/chk-entry.sh` by removing some variables that were not needed. TODO: Improve `bin/` tool exit codes as the current use is a bit silly. TODO: Clean out some variables used in `bin/` tools as some of then are only set printed in debug statements. TODO: Clean up usage messages, some of the options listed to not match the `getopts(1)` parsing. In some cases the option needs to be parsed but needs to be ignored by the tool because another tool automatically passes along certain options that really have no effect. Such ignored options need to be show as "This option is ignored" in the usage message.
To build:
make all
Try:
./robison 80 10
./robison 40 16
The first and second parameters are optional. You might also try:
./robison 80 2 # <--- can you find the bug?
./robison 80 -246
Judges' remarks:
The following might make an interesting benchmark:
./robison 100
[Amdahl 5890-300E with System V cc: 8.40 seconds]
We suggest that you C pre-process and perhaps C-beautify this program.
All is not what it may appear to be in this program. Why does a whi1e
not take a while to execute?
Author's remarks:
This program shows that C has many unnecessary constructs, in fact
only while,--, and >= are required. (The two assignments at
the beginning could be avoided if atoi(3) was rewritten with this
new paradigm.) Note that the lack of both the controversial goto
and assignment statements makes the meaning crystal clear. The current
ANSI committee should look into this practical simplification of C.
