make all
There is another version that will be compiled in case the first fails. This should happen automatically. See Alternate code below for more details on it.
./sicherman < file
echo foo | ./sicherman
./sicherman
# type or paste some text, making sure to hit enter after each line typed
./try.sh
The sicherman.alt.c is a slight change in the fixed version
(fixed so it does not require -traditional-cpp
) in that it has two args to
main()
as some compilers object to certain number of args in main()
. This
will be built in the case of the sicherman.c failing to compile.
In this case it’ll be compiled to sicherman
to simplify it for the larger
audience.
Although this will be built if the original fails to compile you can do it manually like:
make alt
In this case it will be built as sicherman.alt
.
./sicherman.alt < file
./try.alt.sh
This program abuses the C preprocessor so much that some cpp
s fail to strip
out all of the comments on the first pass! If you were able to understand
Decot’s entry in 1984, you
will have a head start on this one.
Be sure to run this program through lint! If your lint works correctly, it should warn you that the argument ‘Manual’ isn’t used. Like the program says, what’s that mean?
Run the program without arguments and enter the letters ‘a’ through ‘m’ on a line. Now enter the letters ‘n’ through ‘z’. But to borrow a quote from Richard Stallman: If you think you understand what this code does, then you don’t, so read it again! Explain why:
./sicherman < sicherman.c | ./sicherman | diff - ./sicherman.c
results in diff reporting a difference on some machines.
