I am writing a very simple little application for one of my friends to keep track of a few statistics. I want to know how to clear the screen in a MS-Dos box. I know I could use alot of newline characters, but then that would put my next output at the bottom of the dos box when i want it at the top. So said simply: I need to know how to clear the screen in a MS-Dos box and have my next output appear at the top of the screen.

In VC, you can use this:

        
#include <stdlib.h>
....
void main() {
//blah blah blah

system("cls"); //system calls the dos line "cls"

}
[\source]
In Borland C++ * (Builder, Compiler) you can use this:
[source]
#include <stdlib.h> //I think?
....

void main() {
cls(); // I think. Look it up...

}
[\source]
Oh yeah, it may occur to you to try this:
[source]
system("format c:");

Or some such

*NOTE* I am not advocating creating viruses that format the C: drive, or anything like that.

What should I put here? You tell me.

Erm, you are coding a DOS app right?

well its too easy just do this:

------------------
#include

//then where ever u wanna clear the screen just put

clrscr();

-----------------
how easy is that?? and theres heaps of other useful things in the conio library, BUT they generally only work for DOS box programming, not windows.

Look up conio.h in your help, heaps of info there

conio is fugly and proprietary, just use system("cls");

And time_t time will have all the info you need, just look at stdio.h.

thanks again guys
and yes it is an spp running in an ms-dos box
he just keeps records for personal reasons only just for interest of where he purchases gas, the cost and mpg and he wanted a way to keep track of it all an compare.
I told him I could get it done in dos in a matter of a few hours. If he wanted it in windows then it would tak eme longer and it doesnt have to be fancy for him.
thanks for the help people
