Question

can anyone help me with a c program?

Answer 1

I'm a little rusty with pointers, but I believe that ftryr needs to dereference.

#include <math.h> should only be done once. Multiple includes messes the libraries up.

math.pow() isn't spelled with a capital P.

Answer 2

Sensible identifiers are always helpful in any language too. A few extra letters in the name can save you from a lot of errors and assumptions.
