clearing screen

**lilhawk2892** · 10-07-2005

this is the only other one besides clrscr i liked but it didnt work so i used

Code:

#include<iostream>
#include<conio.h>
#include<stdio.h>
using namespace std;
int main(void)
{
  int i;   
cout<<"hello world\n";
cin.get();
  for (i = 0; i < 25; i++)
    putchar ('\n');
    cin.get();
    
  return(0);
}

but then it puts you at the bottom of the page i want the top how do i do that

There is no standard way so you can use clrscr() if your conio.h has it or if you are under windows you can use system("cls"). I can't remember the *nix command to clear the screen.

There's no standard way of not reading the FAQ either, but newbies always find lots of interesting ways of not reading it.

Priceless

(Sorry I had to say it)

I usually do it like this:

Code:

#include <cstldib>

//change "clear" to "cls" for win32
inline void clearScreen() { system("clear"); }

of course, you then have to deal with having a potential security hole in your program, but it's a quick and dirty way to get it done, plus it saves you the pain of changing your code in multiple places.

If you don't know how to use it, just call clearScreen() everywhere you need to clear the screen, and it'll call whatever program you tell it to to do your dirty work for you.

edit: I don't actually usually clear the screen - avoid it if at all possible.

edit2: even using this method (I'm using gentoo, hence the linux command), the screen's buffer isn't cleared... you can still scroll up in a console and see everything that was there. I think in windows it may actually clear the buffer (or at least hide it's contents)

>#include <cstldib>
I'm told there's help for lysdexic people. But seriously, is cstldib the header where undefined_behavior ( bosses_email_address ) and read_my_mind() is?

meh... I haven't touched a line of code in over a month... and my mind is in other places

Code:

#include <cstdlib>
