From 37fb84c37c50cf490fd7f38722e185936960fc2d Mon Sep 17 00:00:00 2001 From: Cody Boone Ferguson <53008573+xexyl@users.noreply.github.com> Date: Tue, 14 Feb 2023 03:08:25 -0800 Subject: [PATCH 1/4] All 1990 entries now compile! My first 41st, 51st and 29th (all depending on the base) birthday updates (possibly more will follow but this is not a certainty). All the 1990 entries now compile! In one we used a patch from Yusuke Endoh (thank you Yusuke!) which we credited him in the README and in another we used a tip from him (use -ansi at the compiler line) to get the other to compile (again, thank you Yusuke!). We fixed the others. In the case of 1990/tbr/tbr.c the author had supplied a shorter version and we fixed that one too. Added 1990/.gitignore which has the built files of 1990 so that after doing `cd 1990 ; make all' running `git status .' will not show any untracked files. --- 1990/.gitignore | 18 ++++++ 1990/dds/README.md | 11 +++- 1990/dds/dds.c | 4 +- 1990/dg/README.md | 12 ++-- 1990/dg/dg.c | 124 ++++++++++++++++++++--------------------- 1990/scjones/Makefile | 2 +- 1990/scjones/README.md | 13 ++++- 1990/tbr/README.md | 31 ++++++----- 1990/tbr/tbr.c | 4 +- 1990/westley/README.md | 4 +- 1990/westley/westley.c | 6 +- 11 files changed, 135 insertions(+), 94 deletions(-) create mode 100644 1990/.gitignore diff --git a/1990/.gitignore b/1990/.gitignore new file mode 100644 index 000000000..7f047df8e --- /dev/null +++ b/1990/.gitignore @@ -0,0 +1,18 @@ +baruch/baruch +cmills/cmills +dds/dds +dg/dg +jaw/atob +jaw/jaw +jaw/zcat +pjr/pjr +scjones/scjones +stig/o +stig/o.c +tbr/tbr +theorem/fibonacci +theorem/fibonacci.c +theorem/sorter +theorem/sorter.c +theorem/theorem +westley/westley diff --git a/1990/dds/README.md b/1990/dds/README.md index 8002af0bf..4844aa5e6 100644 --- a/1990/dds/README.md +++ b/1990/dds/README.md @@ -10,12 +10,16 @@ make all - NOTE: This entry may not compile when using modern compilers. ### To run ./dds + +NOTE: this entry uses `gets()` so you might get a warning when compiling and +running this entry. + + ## Judges' comments Give the following lines as input: @@ -25,6 +29,11 @@ Be sure not to run out of fuel! + + Modern compilers could not compile this entry but Yusuke Endoh supplied a patch + which lets it compile.
