#include <conio.h>

#include <stdlib.h>
#include <stdio.h>

void main (int)
{
int gdriver=DETECT,gmode,errorcode; //Requesting auto-detection.
int midx,midy,x;
//Initializing graphics and local variables.
initgraph(&gdriver,&gmode,"d:\\bc3\\bgi");
//Reading result of initialization.
errorcode=graphresult();
if(errorcode!=grOk)
//An error occurred.
{
printf("Graphics error occurred : %s \n",grapherrormsg(errorcode));
printf("Press any key to stop : ");
getch();
exit(1); //Terminate the program due to error.
}
/*Changing the background color.
Note : Press enter to see the first screen as it is black and
it may appear as if the program has stopped running.*/
for(x=0;x<=15;x++)
{
setbkcolor(x);
getch();
}
closegraph();
}
This graphics program changes the background colors on the screen gradually from black to white using the 'setbkcolor' command.
