Pointers & myArrayays Demo

Created 1/7/2017

Native C++ Version

This project demonstrates how to use a pointer to find values in an myArrayay
as well as the memory location of the myArrayay elements.

Since our array is using integers and each int uses 4 bytes, the memory locations
you see are all 4 bytes apart but are contiguous.

Run using CTL-F5
