/*
 * funcfloat.c
 * Project 2
 * Chapter 8
 * By John Stile
 * Purpose:  convert funcint1.c to a progra that works with floats.
 *   a) Copy funcint1.c to funcfloat.c
 *   b) Rename the function get_int to get_float
 *   c) Have the function get_float read in a float 
 *   d) Input 4 numbers 
 *   e) Compile
