Well "professionally" I think you'd want to be compattible on more than just Windows, so I'd do something like this:
Code:
#include <io.h> // For access().
#include <sys/types.h> // For stat().
#include <sys/stat.h> // For stat().
#include <iostream>
#include <string>
using namespace std;
int main( void )
{
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;
}
return 0;

Here's a function that I use to check if a folder exists:
of course, this will also return true whether it's a file or folder. BTW, I use this function to get a folder:

Code:
BOOL FolderExists(CString strFolderName)
{
return GetFileAttributes(strFolderName) != INVALID_FILE_ATTRIBUTES;
}
Code:
CString GetFolder()
{
LPMALLOC pMalloc;
CString strDirectory;
BROWSEINFO bi;
/* Gets the Shell's default allocator */
char pszBuffer[MAX_PATH];
LPITEMIDLIST pidl;
// Get help on BROWSEINFO struct - it's got all the bit settings.
bi.hwndOwner = GetDesktopWindow();
bi.pidlRoot = NULL;
bi.pszDisplayName = pszBuffer;
bi.lpszTitle = _T("Select First Directory");
bi.ulFlags = BIF_RETURNFSANCESTORS | BIF_RETURNONLYFSDIRS | BIF_NEWDIALOGSTYLE;
bi.lpfn = NULL;
bi.lParam = 0;
if (::SHGetMalloc(&pMalloc) == NOERROR)
{
if ((pidl = ::SHBrowseForFolder(&bi)) != NULL)
{
if (::SHGetPathFromIDList(pidl, pszBuffer))
{
strDirectory = pszBuffer;
}
pMalloc->Free(pidl);
}
pMalloc->Release();
}
return strDirectory;
