I am trying to make a program in c++, but i cant make the program because in one part of the code I need to run a python program from c++ and I dont know how to do it. I've been trying many ways of doing it but none of them worked. So the code should look sometihnglike this: somethingtoruntheprogram("pytestx.py");
or something close to that. Id prefer doing it without python.h. I just need to execute this program, I need to run the program because I have redirected output and input from the python program with sys.stdout and sys.stdin to text files and then I need to take data from those text files and compare them. I am using windows.
You have two way of doing that:
system
/ fork
and exec*
/... Using a embedded interpreter is (IMHO) the best way to do it because it gives you more control over the execution of the script, because it's not OS-dependant and it does not rely on your target having a python interpreter (configured as you require).
There's POSIX popen
and on Windows _popen
, which is halfway between exec
and system
. It offers the required control over stdin
and stdout
, which system
does not. But on the other hand, it's not as complicated as the exec
family of functions.
