Exercise

Creating an array

In this exercise, you will practice building and accessing key properties of an array. Understanding what key properties are built in to Bash is important for fully utilizing arrays. For example, when iterating through arrays, knowing their length is very handy. Similarly, knowing how to easily return all array elements is also important for looping and also for checking your work and printing.

In this exercise, you will firstly build an array using two different methods and then access the length of the array. You will then return the entire array using a different special property.
