So I've got an array, and a characterThing, and a factorThing. Let's go down to the console, on the lower left hand corner, and mix a couple of those using c. So here's mixedThing, and into mixedThing I'm going to combine a characterThing, and an intThing. so characterThing is obviously a bunch of characters and int is a bunch of integers.
