The body of 4SIGHT is fairly straightforward and the logical flow can be inferred from the outline below.
#define banner "\"\tThis is 4SIGHT (Version 1.0)\"\n\n"
#define NUM_CELLS 20
#define NUM_SURFACES (NUM_CELLS + 1)
#define DLIMIT 0.0005

3. The following are #include files needed for some of the intrinsic functions such as printf and scanf. The math functions pow and log and the math error routine matherr require math.h. Additional include files are declared when needed. The routine kbhit() requires the header file conio.h.
