How to access the string representation of boost filesystem's path class, and remove the quotes

I want to save the path to the files in a dir as a string. The example from the tutorial pretty much does what I want except that it does it with the quotation marks which I want to be removed. Now I know that I can do it by adding .string() to the path but I simply don't know where to put it in this example.

Hope someone can help me with that.

As you said you need to use .string() method on path to output without quotation marks. Below the modified tutorial example outputting no quotation marks:

#include <iostream>
#include <iterator>
#include <algorithm>
#include <boost/filesystem.hpp>
using namespace std;
using namespace boost::filesystem;

int main(int argc, char* argv[])
{
    if (argc < 2)
    {
        cout << "Usage: tut3 path\n";
        return 1;
    }

    path p(argv[1]);   // p reads clearer than argv[1] in the following code

    try
    {
        if (exists(p))    // does p actually exist?
        {
            if (is_regular_file(p))        // is p a regular file?
                cout << p.string() << " size is " << file_size(p) << '\n';

            else if (is_directory(p))      // is p a directory?
            {
                cout << p.string() << " is a directory containing:\n";

                for (directory_iterator it(p); it != directory_iterator(); ++it)
                    cout << it->path().string() << "\n";
            }
            else
                cout << p.string() << " exists, but is neither a regular file nor a directory\n";
        }
        else
            cout << p.string() << " does not exist\n";
    }

    catch (const filesystem_error& ex)
    {
        cout << ex.what() << '\n';
    }

    return 0;
}
