![Multi-dimensional Array
C programming language allows multidimensional
arrays. Here is the general form of a multidimensional
array declaration −
type name[size1][size2] ……. [sizeN];
For example, the following declaration creates a three
dimensional integer array −
int threedim[5][10][4];](https://image.slidesharecdn.com/lecture16-multidimensionalarray-190525182954/85/Lecture-16-Multi-dimensional-Array-3-320.jpg)

Array[Row][Column][NumberOfElements]
Here,
Row = number of rows
Column = number of columns
NumberOfElements = number of elements in each row
and column](https://image.slidesharecdn.com/lecture16-multidimensionalarray-190525182954/85/Lecture-16-Multi-dimensional-Array-5-320.jpg)

Initialization of a three dimensional array.
Method 1:
int x[2][3][4] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, 12, 13, 14, 15, 16, 17, 18, 19,
20, 21, 22, 23};
Better Method:
int x[2][3][4] =
{
{ {0,1,2,3}, {4,5,6,7}, {8,9,10,11} },
{ {12,13,14,15}, {16,17,18,19}, {20,21,22,23} }
