Clearing the output screen

[Jeeembo]

I'm an amateur c++ programer using Metrowerks CodeWarrior. I currently have a for loop that outputs text using cout. The next time the loop is called, it creates another line of text in addition to the first line. I would like the for loop to clear the output screen each time it is called so only one line is being output at a time.

here is an example on how you might do it:

#include<iostream>
#include<cstring>
#include<ctime>
using std::cout;
using std::flush;
void sleep( clock_t wait );
#define CLEAR_SCREEN system(&quot;cls&quot;);
#define WAIT(x) sleep((long)(x));
#define SECOND 1000



void main()
{
	for(;;)
	{
		cout << &quot;Hello world !&quot;<<flush;// print some text
		WAIT(1.5 * SECOND); // waits before clearing the screen
		CLEAR_SCREEN; //now clear the screen
		WAIT(1 * SECOND); 
	}
}

void sleep( clock_t wait ) 
{
   clock_t goal;
   goal = wait + clock();
   while( goal > clock() )
      ;
}

i did a search and found the following solution which seems alot simpler. I do like the time thing though, thanks for the reply!

#include <iostream>
#include <stdlib.h>

using namespace std;

int main ()
{
for(;
{
cout << &quot;Hello world !&quot; <<endl;
system(&quot;cls&quot;
}
}

Would you have any time to read the lines that are printed on the screen ?

It looks like he just wants to know how to clear the screen :\.

There is a built in &quot;pause&quot; function. It's called sleep.

Sleep(miliseconds)

so just do

Sleep(50);
system(&quot;cls&quot;
