Go through all files in a directory

Question

I'm having some trouble with directories & c++. I'm using Visual Studio 2013 on a Windows setup.

Directory : .../Files which contains some text files (f1.txt , f2.txt , f3.txt)

I need the function to go through all the files in that directory one by one.

A file is open - cout the filename
//Do some stuff 
close - then move to next file

I have the code to read a single file. But I have no idea how to go through all of them & display the names.

void goThroughDirectory()
{
    while("there are remaining files , do something , then go to next one")
    {

        cout << "The Name of the File Currently being processed" << endl;

        // While inside a file
        ifstream FileX("FileName.txt");

        int lineNum = 0;
        string s;

        while (!FileX.eof())
        {
            getline(FileX, s);

            if (s.size() != 0)
            {
                lineNum++;
                cout << s << endl;
            }

        }

    }

}

the expected output should be :

// file name
f1  

// contents
a
b
c

// file name
f2 

// contents
a
b
c

You will need to use `Boost` or an OS API. There are no standard provisions in C++ for iterating through a directory. — Thomas Matthews, Nov 26 '14 at 01:01
