C++ even though C++ started with the goal of being "C with objects."
If you are interested in languages, reading "the Design and Evolution
of C++" is a great base; it explains
][max(0, x + dx)] = entry
field[max(0, y + dx)][x] = entry
return field
There is still overlap done at x = y and x = -y; you could squeeze that
out as well by changing wedge_nz not to put it out, and making circle2
