Functions Pass By Reference, Pass By Value, Pass By Pointer

For this assignment you will create and test PBR ,PBV and PBP functions

Copy over all the files provided for you from 
/home/fac/msarr/public_files/cmps2020/hw/hw01 


first comment out the function bodies you have not completed
then complete one function,
in the main test it then move onto the next one
repeat this process

save your self a lot of trouble and dont try to write all you stuff and then start to compile
you should rarely if ever edit more than 4 lines of code in between attempts to compile... if   you get errors fix them before proceeding.

if you need to comment out sections of your code to test it in your main do that.. one thing at a time so you dont get overwhelmed by a ton of compitation errors

dont put your funcitons obove the main in your main.cpp
they go in funtions.h

to test you need to call each function at least 4 times passing it different values in different order, try to pass in values that might break it.. your job here is to ensure that it works properly all the time

you will complete and test the functions defined in 

File: functions.h

#include "easylogging++.h"
#include "cmpslib19.h"

// put your function bodies here

functions.h -- put your complete functions here main1.cpp -- create a main to test that your functions do what they are supposed to do the one of the functions is done for you as well as the code to test it for full credit: 1. In the main you will need to test ALL of your functions and make sure they are correct 2. Test each of your functions by calling each one at least 3 times with disparate values 3. log the start and end of all functions at the VERY LEAST 4. Give each function a distinct name (no overloading) so that it is clear that you are testing every function 5. make sure your code compiles without warnings
