You don't need to compute it, since there's the M_PI constant in math.h.

This is the default print accuracy, use specific formats to print more 
digits.

Use library functions clrscr or clreol.

You need to post the exact command line(s) used for compiling and 
linking, and the exact procedure you used to set breakpoints and run your 
program under a debugger (you didn't even tell which debugger did you 
use).  Also, please tell which version of what operating system do you 
use DJGPP on.
