- What is the difference between passing by value and passing by reference?
  By value: Passes the value of the memory address that the pointer points to.
  By reference: Passes an alias to “reference” the variable passed in. 
  
- How can pointers be used with inherited or abstract classes?
  Using static methods.
  
- What does it mean for a pointer to be null?
  The pointer does not point to any address in memory.

Functional Programming
----------------------
Throughout our daily or weekly lives, we often do several tasks repeatedly. For example, brushing your teeth, 
introducing yourself to a stranger, making your bed, etc. It would be very convenient if we could snap our fingers
and say, "Make my bed" after every night’s rest. Unfortunately, this is not (yet) the case. Well, in programming, there are
task that programmers know they will have to do over and over again. Maybe calculating the number of days until Christmas, checking if a number is prime, counting letters in a word, etc. It is often very useful to create functions or blocks of reusable code that a program can invoke to execute a this consistent task instead of writing out the code every single time. Instead of writing code and figuring out the logic everytime, functions can be created. For example, static int numOfLetters(String s) { return s.length();}, calculate how long the word (string) s is. Instead of having to rememver the syntax (s.length()), a p
