Python and C++ integration. Python prints string as multiple lines
Question: I'm trying to write a program in python to run a program in C++. It wasn't
working right, so I made the most basic version of each I could. The C++
program merely takes in a string from stdin, and then prints it out. The
Python code is written as follows:

    
    
    import popen2, string, StringIO
    
    fin, fout = popen2.popen2("PyTest")
    msg = ur"Hello, world!"
    print msg
    fout.write(msg)
    print fin.readline()
    

The output, however looks like this:

    
    
    Hello, world!
    Hello,
    

The problem I keep seeing is that spaces seem to break apart the string, even
though it is a string literal. I'm not really sure what to do here. Any
suggestions?


Answer: In C++, `std::cin >> mystring` uses spaces as separators. Use `std::getline`
instead if you want to gobble up a whole line at a time.
