Question 1

How to set up c99sh for OpenMP parallel programming?

Accepted Answer

Create a c99shrc file with OpenMP compiler flags like -fopenmp, and use #pragma directives in your script; the README includes an example computing π with multiple cores.

Question 2

c99sh vs Python for quick C scripting?

Accepted Answer

c99sh is better when you need C/C++ performance or library access without a translation layer, but Python is faster for iteration since it's interpreted. c99sh adds compilation delay but avoids GIL limitations.

Question 3

How to cache compiled binaries to avoid recompilation?

Accepted Answer

Use the -x option when running c99sh, e.g., 'c99sh -x script.c', which saves the binary for future runs, reducing overhead if the source hasn't changed.

Question 4

Can c99sh handle C++ templates and STL?

Accepted Answer

Yes, via the cxxsh symlink and cxxshrc control files, but compilation might be slower due to template instantiation; the README shows Eigen library usage as an example.

Question 5

What if my c99shrc has errors or is missing?

Accepted Answer

c99sh falls back to ~/.c99shrc or defaults, but compilation may fail; use -v to see the exact gcc command and debug issues with flags or includes.

Question 6

Is c99sh good for teaching C to beginners?

Accepted Answer

Yes, it simplifies running code without build systems, but the need for control files and compilation might confuse absolute newcomers compared to pure interpreters like Python.
