visual c++ - How to go up a line in Console Programs (C++)

Question

In C++ I'm trying to go back up a line to add some characters. Here is my code so far:

cout << "









xc9xbb
xc8xbc"<<flush;
Sleep(50);

As you can see, I have 10 newline characters. In my animation, a new block will be falling from the top of the screen. But I don't know how to go back up those lines to add the characters I need. I tried , but that dosen't do anything and dosen't go up the previous line either. Also, what exactly does flush do? I've only been programming in C++ for about 2 days so I'm a newb =P.

Thanks so much!!!

If your console supports VT100 escape sequences (most do), then you can use ESC [ A, like this:

cout << "x1b[A";

to move the cursor up one line. Repeat as necessary.
