Multidimensional array

2. Multidimensional array
An array of arrays known as multidimensional array.
Two dimensional (2D) arrays
An array of array is known as 2D array.
The two dimensional (2D) array in C programming is also known as matrix.
A matrix can be represented as a table of rows and columns.

3. Two dimensional (2D) arrays
float x[3][4]; Here, x is a two-dimensional (2d) array. The array can hold 12 elements.

4. Accessing Two-Dimensional Array Elements
An element in a two-dimensional array is accessed by using the subscripts, i.e., row index and column index of the array. For example int val = x[2][3];

5. How to initialize a Two-Dimensional Array
There is more than one way to initialize a multidimensional array.

9. Three-Dimensional Array
Similarly, you can declare a three-dimensional (3d) array float y[2][4][3]; Initialization of a three dimensional array in a similar way like a two dimensional array.
Initialization of a three dimensional array.
You can initialize a three dimensional array in a similar way like a two dimensional array. Here's an example,
int test[2][3][4] = {
{ {3, 4, 2, 3}, {0, -3, 9, 11}, {23, 12, 23, 2} },
{ {13, 4, 56, 3}, {5, 9, 3, 5}, {3, 1, 4, 9} } }
