Thread: Is it sphere

I make the following code for sphere in borland c++ ver 3.0
is it right sphere?

Code:

# include<graphics.h>
# include<conio.h>
int main()
{
int i,cx=220,cy=300;
int gd=0,gm=0;
initgraph(gd,&gm,"");
cleardevice();
circle(cx,cy,80);
for(i=10;i<=80;i++)
{
ellipse(cx,cy,90,270,i,80);
ellipse(cx,cy,270,90,i,80);
ellipse(cx,cy,90,270,80,i);
ellipse(cx,cy,270,90,80,i);
}
getch();
closegraph();
restorecrtmode();
}

does it represent a 3rd dimension ?
if not then which is the right way to do that in above code.
