No. You are running into problems when you mix floats and doubles in scanf
and sprintf.

Note that k is declared as double.

I believe this should be "%7lf", for a DOUBLE number.  Same mistake is made
in the next line of the program.

                              ^^^^^
Sorry for posting this.....but it illustrates a BAD HABIT of confusing float
with double (a habit I used to have).
