Write a program to draw circle using mid-point algorithm.

``` #include #include #include #include #include void driver() { int gd=DETECT,gmode; initgraph(&gd,&gmode,"c:\\tc\\bgi"); } void circlept(int xcentre,int ycentre,int x,int y,int radius) { putpixel(xcentre+x,ycentre+y,RED); putpixel(xcentre-x,ycentre+y,RED); putpixel(xcentre+x,ycentre-y,RED); putpixel(xcentre-x,ycentre-y,RED); putpixel(xcentre+y,ycentre+x,RED); putpixel(xcentre-y,ycentre+x,RED); putpixel(xcentre+y,ycentre-x,RED); putpixel(xcentre-y,ycentre-x,RED); } void midptcircle(int xcentre,int ycentre,int radius) { int p,x,y; x=0; y=radius; p=1-radius; circlept(xcentre,ycentre,x,y,radius); while(x<y) { if(p<0) x++; else { x++; y--; } if(p<0) p=p+ 2*x +1; else p=p+2*(x-y)+1; circlept(xcentre,ycentre,x,y,radius); } } void main() { int xcentre,ycentre,radius; driver(); getch(); setbkcolor(DARKGRAY); cleardevice(); printf("\n Enter x co-ordinate of centre::\t"); scanf("%d",&xcentre); printf("\n Enter y co-ordinate of centre::\t"); scanf("%d",&ycentre); printf("\n Enter Radius of the circle:: \t"); scanf("%d",&radius); cleardevice(); midptcircle(xcentre,ycentre,radius); getch(); closegraph(); } ``` </div>
