    Directory Creation in C++

    Hi, I'm a beginner in C++ (teaching myself basically) and I was wondering how to create a directory using C++ as I have discovered that ofstream won't create a file if the directory it is to be created in doesn't exist.

    there is the mkdir function in dir.h though this is compiler specific.

    MSVC++ doesn't seem to have dir.h, but you could try direct.h
    I can't find any documentation for it, but a quick browse of the file listed some functions that may be what you need.

    >documentation for it

    www.msdn.microsoft.com

    PHP Code:
    Example

    /* MAKEDIR.C */

    #include <direct.h>
    #include <stdlib.h>
    #include <stdio.h>

    int mainvoid )
    {
       if( 
    _mkdir"\\testtmp" ) == )
       {
          
    printf"Directory '\\testtmp' was successfully created\n" );
          
    system"dir \\testtmp" );
          if( 
    _rmdir"\\testtmp" ) == )
            
    printf"Directory '\\testtmp' was successfully removed\n"  );
          else
             
    printf"Problem removing directory '\\testtmp'\n" );
       }
       else
          
    printf"Problem creating directory '\\testtmp'\n" );

       return 
    0;
    }


    Output

    Directory 
    '\testtmp' was successfully created   
     Volume in drive C is CDRIVE
     Volume Serial Number is 0E17

    When in doubt, read the FAQ.
    Then ask a smart question.

    i have a very very very very much muhco much mucho easier way to do that.

    Code:
    system("mkdir directory/path/here");
    and the include file is process.h

    True. That is an easy way, but I seem to see people shy away from using "system". Perhaps because it's not portable. There may be better reasons too...I can't remember, but it's allways been in my mind not to use system. (I think it's supposed to be much slower too).

    Yes, but the system function is terribly slow. Even for people who don't even consider efficiency it is slow enough to cause hesitation.

    >and the include file is process.h
    process.h is a nonstandard header file, you can also find system in cstdlib, or iostream which sometimes includes cstdlib.

    >Perhaps because it's not portable.
    This is true, but working with directories is also not portable so there's no real problem there.
