Implementation of Midpoint Circle Algorithm

int x = 0; int y = radius;

int p = 1 - radius;

irclePlotPoints (xCenter, yCenter, x, y);

while (x < y)

 {

 x++ ;

if (p < 0) p +=2*x +1;

else

{

y--; p +=2* (x - Y) + 1;

}

circlePlotPoints(xCenter, yCenter, x, y)

}

}

{

setpixel (xCenter + y, yCenter + x);

setpixel (xCenter - y , yCenter + x);
