C implementation of Midpoint Circle Drawing Algorithm

Similar to previous post, following is the program for Midpoint Circle Drawing Algorithm in C.

PROGRAM CODE

#include<stdio.h>

#include<conio.h>

#include<graphics.h>

int gd=DETECT,gm,i,x,y,r,xmid,ymid;

float p;

void main()

{

clrscr();

printf("\nEnter radius of circle=");

scanf("%d",&r);

initgraph(&gd,&gm,"c:\\tc\\bgi");

x=0;

y=r;

p=1.25-r;

do

{

xmid=getmaxx()/2;

ymid=getmaxy()/2;
