Write a C Graphics Program to draw a Straight Line

#include<stdio.h>
#include<conio.h>
#include<graphics.h>
main()
{
int gd=DETECT, gm, x1, y1, x2, y2;
initgraph(&gd, &gm, "C:\\TC\\BGI");
clrscr();
printf("Enter the start point coordinate:");
scanf("%d%d", &x1,&y1);
printf("Enter the end point coordinate:");
scanf("%d%d", &x2,&y2);
setbkcolor(DARKGRAY);
setcolor(RED);
line(x1, y1, x2, y2);
outtextxy(20, 450, "Press any key to continue...");
getch();
closegraph();
return 0;
}

Output:
