The simplest (but not really efficient) way is simply to issue the Unix
clear command using the C system(3) function. This is portable because all
Unix and Unix derivatives support this command, and the system(3) function
is part of standard C language, and available in C++.
int rv;
rv = system("clear");
if (rv != 0) {
// error processing if desired
}
There are better ways, such as using the appropriate codes for clearing the
screen. (I don't have the codes at my fingertips), or a more portable way
is to use curses(3).
