(I use Emacs v29.1.90 for MS-Windows; gcc 10.3.0)
Here's an Org file:
#+BEGIN_SRC C
#include <stdio.h>
#include <omp.h>
int main() {
#pragma omp parallel num_threads(3)
printf("0"), printf("1");
}
#+END_SRC
# Local Variables:
# eval: (require 'ob-C)
# org-babel-C-compiler: "gcc.exe \
# -std=c17 -Wall -O0 \
# -fopenmp "
# org-confirm-babel-evaluate: nil
# End:
Executing the C code block usually outputs:
#+RESULTS:
: 10101
#+RESULTS:
: 1101
This output was unexpected, so I personally ran the temporary EXE file generated by Org-Babel:
Windows Terminal
PS D:/Tmp/babel-Xyz123> ./C-bin-Xyz123.exe
010101
As you can see, this program should output 6 characters.

I found that the leading '0's of result will always be trimmed,
so `010101` will be printed as `10101`.
It seems to be a feature?
If so, I think this is reasonable and convenient.
But how can I disable it?

The above invocation is AFAIU not an accurate reproduction of what
happens when this program is invoked from Emacs on MS-Windows. Emacs
on Windows communicates with subprocesses via pipes, so a more
accurate reproduction would be something like
C-bin-Xyz123.exe | more
IOW, you need to invoke the program with its output redirected to a
pipe.
In any case, please report this to the Org developers first, and only
if their analysis shows this is a core Emacs problem, come here.
Thanks.

I think this is a question for Org developers.

Understood. (I sent it here because the file ‘ob-C.el’ says “This
file is part of GNU Emacs.”)

Org is indeed part of Emacs, but is developed by a separate team, and
has its own forums for reporting problems.
