How to find out if a folder exists and how to create a folder?

Question

I'm trying to create a folder if it doesn't exist. I'm using Windows and I am not interested on my code working in other platforms.

Never mind, I found the solution. I was just having a inclusion problem. The answer is:

#include <io.h>   // For access().
#include <sys/types.h>  // For stat().
#include <sys/stat.h>   // For stat().
#include <iostream>
#include <string>
using namespace std;

string strPath;
   cout << "Enter directory to check: ";
   cin >> strPath;

   if ( access( strPath.c_str(), 0 ) == 0 )
   {
      struct stat status;
      stat( strPath.c_str(), &status );

      if ( status.st_mode & S_IFDIR )
      {
         cout << "The directory exists." << endl;
      }
      else
      {
         cout << "The path you entered is a file." << endl;
      }
   }
   else
   {
      cout << "Path doesn't exist." << endl;
   }

The POSIX-compatible call is mkdir. It silently fails when the directory already exists.

If you are using the Windows API, then CreateDirectory is more appropriate.
