+1. A string is collection of characters that can make up words or sentences. In order to read a string in C, strings have to be split into character arrays which break apart the string into individual chars.
+
+2. Arrays are advantageous because they give the programmer complete control over what's inside and organizes data. It is easy and efficient to create an array and add/delete things from the array. A disadvantage is that they can be difficult to navigate sometimes and require a lot of loops to organize/search through.
+
+3. The compiler won't implicitly generate the address of the first element in the array when an array is initialized without values originally added to it.
+
+4. The easiest way to compare two strings to see if they're equal is the function strcmp(). If 0 is returned, the strings are equal.

+I wanted to do something a little nicer than just creating a counter for each letter so I tried to do this (alphabetizes and splits the array). It mostly works except it doesn't recognize uppercase and lowercase as different and sometimes has a few glitches. I've been looking at it for a while and was wondering someone could advise me on how to fix this but I can look more tomorrow. Sorry it isn't 100% yet, but I thought it would be good to try something a little more complex.
