C++ Multidimensional Arrays

                              C++ Multidimensional Arrays

In C++, you can create an array of an array known as multidimensional array. 

For Example : 

int   x [3] [4];

Here, x is two dimensionall array . it can hold a maximum of 12 elements.

You can think this array as table with  3 rows and each rows has 4 columns .

for example. :

Three-dimensional array also works in a similar way. For example :

float x [2][4][3];

This array x can hold a maximum of 24 elements. You can think this example as : Each of the 2 elements can hold 4 elements, which makes 8 elements and each of those 8 elements can hold 3 elements. Hence, total number of elements this array can hold is 24.

Multidimensional Array Initialisation :

you can initialise a multidimmensional array in more than one way.

Initialisation of two dimensional array:

int test[2][3] = { 2, 4, -5, 9, 0, 9};

Better way to initialise this array with same array elements as above.

int  test[2][3]  = { { 2, 4, 5,},{9, 0, 0}};

Initialisation of  three  dimensional  array

int test [2][3][4] = {3, 4, 2, 3, 0,, -3, 9, 11, 23, 2, 13, 4, 56, 3, 5, 9, 3, 5, 5, 1, 4, 9};

Better way to initialise this array with same elements as above.

Example - Two Dimensional Array

C++ program to store temperature of two different cities for a week and display it.

Output :

Example - Three Dimensional Array

C++ Program to store value entered by user in three dimensional 

array and display it.

Output :

Enter 12 value:
