Answer 1

Not sure I believe the answer above!

X = 5.0; Y = 0.0; Z = X/Y;

This will give a floating point exception....

The problem would appear to be that prime_pf is only initialised for 3 elements. So the modulo is attempting to divide by zero. BTW, if you add \n to your printf statement, and add the extra statement fflush(stdout); you are more likely to see the debug output before the program errors.
