Huh?  What do you mean "write a file open"?  You want to read a
C source file and execute the C source?  If you have access to
a C interpreter, I guess you could invoke the interpreter from
python using popen, and feed the C source to it.  Alternatively
you could invoke a compiler and linker from C to generate an
executable and then execute the resulting file.

You're going to have to explain clearly what you mean by
"EXECUTE_C_PROGRAM".  If you want to, you can certainly run a
binary executable that was generated from C source, (e.g. an
ELF file under Linux or whatever a .exe file is under Windows).

Solution to what?
