For example consider an array with 5 numbers: [ 10, 9, 99, 71, 90 ] Here, the 1st value in the array is 10 and has the index value [0] associated with it; the 2. nd. value in the array is 9 and has the index value [1] associated with it, and so on. The last value (in this case the 5. th. value) in this array has an index [4]. This is called ...
