I am not sure but I believe Windows has a #define somewhere. SOmething along the lines of

#ifdef WINDOWS
// command to clear screen in windows
#else
Clear(); // not sure if this is the unix command... been
// 2 years since i used a unix system for coding
#endif

hey Mat,

I tried the ways you said. They didn't work. So, is there any other ways that will make sure to clean the screen in both UNIX and windows systems..

 

[Zyrenthian]

I think this is the way to go. Instead of #ifdef windows , if you put a -D _UNIX in your make file and check on that instead it should go. (Once again, please keep in mind I have not worked on unix in a while and dont remember exaclty how to define things in a make file. I think the underscore is ignored with the -D but check on that please)

It's late getting it to you but this will work too.

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

int main()

{
cout << &quot;Text before the clear screen.&quot; << endl;
system(&quot;CLS&quot;
cout << &quot;Text following the clear screen.&quot; << endl;
return 0;
}

system works in visual c++?

In Windows we can use clear() of conio.h. But for UNIX there is no console headers. So it is better to use &quot;clear&quot; command of UNIX system using 'system' function of stdlib.h.
include the following line at header includes.
#include <stdlib.h>

and use the following line where you want to clear screen.
system(&quot;clear&quot;

Any way to add logic for portability?

if //TEST FOR PLATFORM//
system(&quot;clear&quot;

else
system(&quot;cls&quot;
