cout position

Hi all,

Can anyone help with me positioning the output of std::cout in a console application? Basically I want a loop which outputs a sequence of characters (a single letter for example) in the same position each time, replacing the previous character.

Thanks,

That would have to be done with OS-specific methods. There's nothing about it in the standard library.

Thanks, I figured standard libraries wouldn't allow such things on a stream, however I managed to cheat by simply using the carriage return \r along with std::flush to 'cheat' :P

Code:

---

char progBar[] = {'|', '/', '-', '\\'};
int progPos = 0;

while (something) {
    std::cout << "\r" << progBar[progPos] << std::flush;
    progPos++;
    if (progPos == 4) {
        progPos = 0;
  }
}

Ugly, but it seems to work, though it doesn't produce very consistent results depending on the loop conditions (mine happens to be waiting on InternetReadFile() so it's quite delayed at times).

If you're programming in Windows you can use SetConsoleCursorPosition to position the cursor before a cout.
