    std::string filename = "hi.py";
    std::string command = "python ";
    command += filename;


    FILE* in = popen(command.c_str(), "r");

Where (what directory) is your C program running from? Try running python with the full path where it is installed. — Vini.g.fer, Nov 04 '15 at 16:09
Is `python` in the standard program search path? Can you, from a command prompt and in any directory, start Python by writing the command `python`? — Some programmer dude, Nov 04 '15 at 16:10

You want to use the full path to your python executable, something like:

std::string command = "/usr/bin/python ";

I just gave an *example*, you have to use *your* path – Paul Evans Nov 04 '15 at 16:33
I use like this...... std::string filename = "C:/Users/BirunthaG/Desktop/print.py"; std::string command = "C:/Python27/python "; @ Paul Evans – Biruntha G Nov 05 '15 at 00:58
