 * Assignment5.c
 * Chapter 8
 * By John Stile
 * Purpose: Create a new functions source file and header file with add two functions.  
 * Write a program that employs the user  functions in the new file.
 *
 * I stole my code from program Chapter 7, Project2.c.
 * Devided the code into 3 files:
 * 
 * 1. Header file:   Assignment5.headers.h
 * 2. Function file: Assignment5.funcitons.c (includes Assignment5.headers.h)
 * 3. Main file:     Assignment5.c           (include Assignment5.headers.h)
 *
 * Build it: Preprocessing --> Compilation --> Assembly --> Linking --> a.out  
 *                         .i              .s           .o           
 *   // compile but don't link (don't load functions)    
 *   gcc -c Assignment5.c -o Assignment5.o
 *
 *   // Compile but don't link (don't load functions)  
 *   gcc -c Assignment5.functions.c -o Assignment5.functions.o 
 *
 *   // Link objects, and includ math pow funciton
 *   gcc Assignment5.o Assignment5.functions.o -lm -o Assignment5
