screen change color
#include<stdio.h>
#include<graphics.h>
#include<conio.h>
void main()
{
int p=DETECT,q;
initgraph(&p,&q,"");
clrscr();
setbkcolor(BLACK);
printf("THIS IS A TEST PROGRAM");
getch();
}
In the following program has got no error and I understand every function I used above.
But whenever I use initgraph function and then clrscr() function I get 75% of my screen in any other color usually gray
and 25% is always black. I cannot correct it even if I use setbkcolor() after each clrscr() command.
I could not figure out what is wrong and which function is making problem.
PLEASE HELP................

hi nabeen
u should use cleardevice() command to clear the screen in graphics mode. clrscr() is for text mode only.
#include<stdio.h>
#include<graphics.h>
#include<conio.h>
void main()
{
int p=DETECT,q;
initgraph(&p,&q,"");
//------------------------
clrscr();// for text mode
cleardevice();//for graphics mode
//------------------------
setbkcolor(BLACK);
printf("THIS IS A TEST PROGRAM");
getch();
}

I've tried using the clrscr(); but it shows an error while compiling in Microsoft Visual C++ 6.0 . What libraries do i need to initialise in order to use the function?? How do i go about it using MS VC++ 6.0 as my compiler?
Just out of curiosity!

Try using _clrscr () ; instead of clrscr () ; and see if it works (include <conio.h>, of course).
_clrscr(); also does not work...
any other suggestions??

clrscr () is screen-based, and VC++ is window-based. clrscr () is supposed to clear the "screen". I guess VC++ starts the execution of your program in a cleared command window anyway (I've not worked much on VC++ - I'm more into Java.... that's why I don't have VC++ on my system too. I just have an old Turbo C++ compiler, which I'd used once while working with micro-controllers).

no..there is an ERROR while compiling...
that's what i mean by not working....
and even though MS VC++ is windows based, the programs created are run in DOS

The error must be that the function clrscr () is not defined/ declared or that it needs a prototype.
is it possible for u to post a working solution for this problem??
because i do not get what u mean!

What is the error?
just a compiling error...says that clrscr () is not declared
Yeah! Like I said:
>> The error must be that the function clrscr () is not defined/ declared or that it needs a prototype.
Sorry, deejay, don't know how to help you with that on VC.

i want tsr of this function. can any one provide?
#include <conio.h>
#include <graphics.h>
#define RETURN_EXIT_SUCCESS 0
int main()
{
int driver,mode;
detectgraph(&driver,&mode)
initgraph(&driver,&mode,"C
cleardevice();
setbkcolor(BLACK);
printf("%s","THIS IS WAT YOU NEED. \n");
getch();
return RETURN_EXIT_SUCCESS;
}
