    telling what directory you're in

    was wondering if there was a relatively simple way to determine what directory the program is in on the harddrive, so i could tell the user exactly where to find a file that the program creates. something like the following...

    <output to console>
    Database printed to: C:\Windows\DB Program\database.txt

    any help would be much appreciated! thanks.

    GetCurrentDirectory(DWORD BufferSize, LPSTR Buffer);

    Code:
    #include <iostream>
    
    
    int main(int nArg,char** szArgz)
    {
    	std::cout << szArgz[0];
    	return 0;
    }

    Sorry, I didn't mean any offense .

    You need windows.h to use GetCurrentDirectory(). If you're doing this in DOS, include dir.h and use getcurdir(int drive, char *directory);

    EDIT: Or you could do what Fordy said, but if you change the directory during runtime that will be outdated. But I guess you wouldn't do that normally...

    Code:
    #include <iostream>
    
    int main(int nArg,char** szArgz)
    {
      std::cout << szArgz[0];
      return 0;
    }
    This code may not work correctly. The argument vector's first element can be an empty C string. Even if it does contain the name of the program, the entire path may be omitted. The output could legally be

    C:\Windows\DB Program\database.txt

    or merely

    database.txt

    You would be better off using GetCurrentDirectory in windows.h.

    An adress to a buffer (empty char array) where the path will be stored.
