C++ Pointer Tutorial

Because pointers can be ugh

"Regular" variables (not pointers)

To understand a pointer, let's review "regular" variables first. If you're familiar with a programming language without pointers like JavaScript, this is what you think when you hear "variable".

When declaring a variable by identifier (or name), the variable is synonymous with its value.

# I've found that the "Migrate to AndroidX" converter in Android Studio doesn't work very
# well, so I wrote my own script to do the simple job of converting package names.
#
# You can download a CSV of package names here: https://developer.android.com/topic/libraries/support-library/downloads/androidx-class-mapping.csv
#
# It'll run faster on a clean build because then there are fewer files to scan over.
#
# Uses `gsed` because I'm on a Mac. Can easily replace with `sed` if you don't have `gsed`.
