Array

• Array: a construct (data structure) that can be used to collect and organize sequences of numbers.
  • each array element (number) may be accessed by its index--its position in the array.

  • indeces typically begin with 0 and end with $N-1$, where $N$ is the length (number of elements) in the array.
  

• A table may be viewed as an array (an array may be used to implement a table).
