Answer 1

test.c: In function ‘main’:
test.c:6:37: warning: integer overflow in expression [-Woverflow]
      double denominator =  10000*180*3600 ;
                                     ^

Is the error when I compile. Your overflowing ints and casting to a double.

   double denominator =  10000.0*180.0*3600.0 ;

Fixes the issue
