Question

If you don't mind helping I'm trying to figure out why my code isn't compiling. I have tried to figure it out to no avail. I don't want to cheat so just give me some advice or if I made any obviously dumb errors just let me know. Here is my code and the compiler errors. Thanks guys!


Errors:

p2print.c: In function `docalc':
p2print.c:106: error: incompatible type for argument 2 of `extraction'
p2print.c: At top level:
p2print.c:170: error: conflicting types for 'extraction'
p2print.c:17: error: previous declaration of 'extraction' was here
