Problem with drawing Yin Yang?

I wrote a program to draw a Ying Yang in dos mode(BGI).
The problem is that when the ying yang has rotated, and it's at its biggest, the x axis is bigger than the y-axis.
It should be the same.

Forgive the flickering, im learning visual pages just now.

sorry but i think this should be in the C++ forum

DOH!!!!:D
My mistake. Should have paid more attention.
I'll ask one of the mods to move it to another board.

Moved

I havent got the graphics header i assume this is because i need to install suomething... what?
