title: Clear screen in C and C++ on UNIX-based system?
body: <p>I want to know: how to clean screen on an UNIX-based system? I searched on the Internet, but I've just found how to do it on Windows: system("CLS")
  I don't want exactly to clean cpmpletely the screen, but I want to open a "new page", such as in the NANO and VI editors. Thanks</p>
