Grahics and Importance

The following functions compose the Borland Graphics Interface and are usually available for 16 bit DOS applications. Use them to create onscreen graphics with text. They are defined in graphics.h.
   
#include<stdio.h>
#include<conio.h>
#include<graphics.h>
int main()
{
int gd=DETECT,gm;
initgraph(&gd,&gm,"f:\tc\bgi");
getch();
closegraph();       /* closes down the graphics system */
return 0;
}
   
#include<stdio.h>
#include<conio.h>
#include<graphics.h>
int main()
{
int gd=DETECT,gm,error;
initgraph(&gd,&gm,"f:\tc\bgi");
error = graphresult();
if (error != grOk)  
    {
    printf("Graphics error occurred");
    printf("Press any key to halt:");
    getch();     /* wait for a key */
    exit(1);
    }
