+ * Andrei Florea - CST 116 - Chapter 9 - Debugging & Functions
+ *
+ * Chapter 9 Questions & Answers (it didn't specify which questions, so I'm assuming all?)
+ *  How does a computer know where to go back to?
+ *      - It knows because of a parameter that is called the return address, which lets the computer know
+ *      where to go back to after executing the function.
+ *
+ *  How does it maintain the state of all variables when a function is called?
+ *      - The state of all variables is saved before a function call, and when creating a function,
+ *      you can decide whether you want to pass the parameters as reference ( reference to the memory location )
+ *      or passing the value of the variable which both can alter the original values, but they differ on how.
+ *      Passing by reference, any manipulation inside the function to the given parameter variables will alter it,
+ *      but if its passed by value, it has to return the variable(s), as it creates a copy of the original variables.
