+// EXERCISE: Get and Set Array Elements
+//
+//  1. Use the 01-declare-empty exercise
+//  2. Remove everything but the array declarations
+//
+//  3. Assign your best friends' names to the names array
+//
+//  4. Assign distances to the closest cities to you to the distance array
+//
+//  5. Assign arbitrary bytes to the data array
+//
+//  6. Assign a value to the ratios array
+//
+//  7. Assign true/false values to the alives arrays
+//
+//  8. Try to assign to the zero array and observe the error
+//
+//  9. Now use ordinary loop statements for each array and print them
+//      (do not use for range)
+//
+//  10. Now use for range loop statements for each array and print them
+//
+//  11. Try assigning different types of values to the arrays, break things,
+//     and observe the errors
+//
+//  12. Remove some of the array assignments and observe the loop outputs
+//      (zero values)
+//
+//
+// EXPECTED OUTPUT
+//
+//  Note: The output can change depending on the values that you've assigned to them, of course.
+//        You're free to assign any values.
