If you absolutely do not care about portability, just emit the same sequence of characters that clear does.

$ clear | od -c
0000000 033   [   H 033   [   2   J
0000007
$ : "Oh, it is ESCAPE [ H ESCAPE [ 2 J on my computer"
$ cat clear_fun.cc
#include <iostream>
void clear() { std::cout << "\033[H\033[2J" << std::flush; }
$

Standard C++ doesn't talk about a "screen" or something. On UNIXes you can use ncurses. Generally, this just use terminal control codes. Mostly, you can assume that VT100 is the terminal and you can just use the various control codes. How to do it on Windows terminals I don't know.
