why not use vectors? So (0,0) centered pie of radius r is determined by: u = (cos(a0),sin(a0)) v = (cos(a1),sin(a1)) x^2 + y^2 <= r^2 // circle (x,y) x u -> CW (x,y) x v -> CCW the CW/CCW is determined by computing 3D cross product and examining the sign of results z coordinate… so … Read more
For a list of C standard C headers (stdio, stdlib, assert, …), prepend a c and remove the .h. For example stdio.h becomes cstdio. For other headers, use extern “C” { #include “other_header.h” }

<graphics.h> is very old library. It’s better to use something that is new Here are some 2D libraries (platform independent) for C/C++ SDL GTK+ Qt Also there is a free very powerful 3D open source graphics library for C++ OGRE
