\1 Glitch

Feedback & Bugs
#1

Working on “The two piles difference” community puzzle and this error pops up when I try to compile my C program.

Errors
/tmp/Answer.c: In function ‘permute’:
/tmp/Answer.c:129:5: error: stray ‘\1’ in program
for (int i=0; i<=list[level].count; i++)
^

I wouldn’t bother you about it, but it’s the second time it has happened. I fixed it the last time by re-typing the offending line.

I have no idea how a \1 character got entered, hence I call it a glitch.

#2

Did you copy-paste the code?

#3

I copied the error message with the offending line, but not the original code. This problem hasn’t shown up again, so I’m not going to worry about it. Besides I have other problems to worry about now.

#4

New problem, new glitch.

Errors
/tmp/Answer.c:35:1: error: stray ‘\1’ in program
item_type* additem(char* s)
^

Original line copied from program:

item_type* additem(char* s)

This time I am working on the Longest Palindrome community puzzle.

#5

Here we go again:

Errors
/tmp/Answer.c: In function ‘main’:
/tmp/Answer.c:43:5: error: stray ‘\1’ in program
fgetc(stdin);
^
This time I am working on the Turing machine community puzzle.

#6

I think you somehow got an unreadable character into your source code. Maybe something went wrong when you copy/pasted something from a website. Character 5 on line 43. Try to delete the line and retype it.

#7

Retyping the line fixed it. Hard to see how the bad character got it there, it was one of the original lines from the template. Or maybe it’s because I put a newline before the fgetc.

#8

Fixed one line and boom, the same problem shows up on another. Fixed it the same way. I might have to reboot (oh no!).
