Clearing the consule window in C++

I want to tidy up my UI for my program by clearing the screen to make it look more tidy on the consule mode in C++. I am using the IOSTREAM libary. Does anybody know how you clear the consule screen in C?

I want to the CLS thing in BASIC.

Thanks for any help, I have tried google and books but found nothing.

 

what compiler are you useing?

if it supports conion.h (console input output)

Code:

#include <conio.h>

int main()
{

           printf("arse hats");
           getchar();
           clrscr();

           getchar();
           return;
}

ish

clears the console screen and returns the cursor to top left.
the library also contains gotoxy, usefull for makeing a tidy UI


conio.h is not ANSI C so be careful if portability is an issue

 

Microsoft Visual C++ (all 32 bit editions) don't support clrscr() in its conio.h. You have to implement it yourself. See below for someone who has done it:

btw AT it's spelled console

Thanks I will have a look at that. I'm using C++ NET at uni but Bloodshed DEV C++ at home so portability is a major issue.

 

The toothpaste people have a university

 

If you're coding for the Windows environment then the code in the link I gave you will be fine but it's strictly Windows environment.

why not just print lots of \n's the scroll everything off the top of the console? should port to other platforms well enough?
int scrLines = 30;
for (int i = 0; i < scrLines; i++) cout << "\n";
should do it (for a 30 line console) or is my console c++ that rusty?

cheers

I thought of doing something like that but not shure how that would work in a windows enviroment as it /n makes it scroll down rather than up.

That will just add a long scrollbar to the screen and leave lots of white space I think.

I did so somthing like that in Java in college but I was working in a DOS environment then.

I wlll try it later though when I am on my dekstop, I am in bed atm on my ancient P233 laptop.

 

Julians idea would clear the screen, but would leave the curser at the bottom i think

 

I try it, I am sure its pretty easy to move the postion of the cursor using x,y commands but then I might as well use Micheal's suggestion as that involves using other libaries too.

I will have a play.

 

You could read the Windows documentation, this is immediately relevant. http://msdn.microsoft.com/library/en-us/dllproc/base/clearing_the_screen.asp

If you're writing Windows apps I think you could find a free 'curses' implementation for Windows. This would give you Unix source compatibility but is a whole new thing to learn.

But if all you want to do is clear the screen when your program starts/exits then the 'system ("cls");' approach rules. If you have compilation problems then just use conditional compilation to remove the call from the Bloodhound build.

Thanks, that method worked

{
system("cls");
}

I just need to check it works on the .NET compiler though.

 

Do you have back problems or something?

Lol I was just tired and my laptop is silent unlike my noisy desktop.

 

have you tried

 

If I wasn't feeling so down (because of a couple of problems at uni and my social life crisis) I would actually find that quite funny

 

LOL Les that's a classic
