I'm working on a project simulating a stock market. People buy and sell a stock and I would like to call each turn a script to try a strategy against the market.
What I want is a function in C++ which send an vector of integer as argument to a vba or python script which return an array of 3 integers.
I've searched for a solution but all i could find is a way to execute a script in python, but I don't know how I can send and get an argument from this script. I think my problem is common but i don't know where to head to find a solution.
Thank you!

On windows you use the function CreateProcess() to start another program. Use the full path of the python interpreter as the first argument. Start the second argument with the path to the python script.
If you can fit a string representing your vector in 32768 characters, you can supply the vector in the second argument to CreateProcess.
A more flexible option is create a child process with redirected in- and output, as shown here. You can then write the vector to the standard input of the python process and read the answer back from its standard output.
