If argc is not equal to 5, you print an error message *and then
continue with the rest of the program, using garbage input*.

strtod is capable of telling you about errors. Use that capability.
Don't ask us how; look it up.

atoi() is *not* capable of telling you about errors. Use strtol()
instead. And check for errors.

For every standard function you use, you must have a #include
directive for the corresponding header.

Ah Keith good to hear from you. I have changed that if statement to include
an exit(EXIT_FAILURE) call so the program exits and there's no seg fault.
I am just used to using atoi. So there's no error checking. I haven't
included that at all in this program I usually do that with streams and
such. It would be a good thing to start. I'll check out strtol.
