Given the following 2D array int array 3 7 8 5 1 3 2 0 4

Given the following 2-D array int[][] array = { { 3, 7, 8}, {5, 1, 3}, {2, 0, 4}, {9, 1, 6}}; What value is stored in array[2][1]?

Solution

In a Multi-Dimensional Array, we declare and Access the Arrays using the Rows and Columns.

We have the given Array:

int[][] array = {{ 3, 7, 8}, {5, 1, 3}, {2, 0, 4}, {9, 1, 6}};

For your better understanding write it like this:

int[][] array = {

{ 3, 7, 8},

{5, 1, 3},

{2, 0, 4},

{9, 1, 6}                };

This given array has Rows and each row has 3 elements, now to access any of the elements we use the array name and then the

[Row Number] [Element Number]

Here the name of the array is array itself, Now,

array [2][1] will access the 2nd row, and 1st element of it.

So, in the 2nd Row we have, {5,1,3}, and the first element is 5

So, array [2][1] will return the 1st element of 2nd Row, that is \"5\".

This is all for the given question.
