A Logic/Loops Testing Document

After changing and debugging and re-editing this, I am unable to find a solution to the problem.

You have a type mismatch between your scanf format descriptor and your definition of x,y,z. %f presumes a float. You've declared x,y,z to be double. Either change x,y,z to float or change your scanf descriptor to %lf.
Thank you,
My program works now.
