Multi-dimensional array

Multi-Dimensional Arrays

In C programming, a multi-dimensional array is essentially an array of arrays.

It can be thought of as a table with rows and columns, where each element can be accessed using multiple indices.

The most common multi-dimensional array is a 2D array, but C also supports arrays with more than two dimensions.

In C, the syntax to declare a multi-dimensional array involves specifying the dimensions within the square brackets.

Here’s the general syntax:
data_type array_name[size1][size2]…[sizeN];

It’s important to note that when initializing the array at the time of declaration, you can use nested curly braces to specify the initial values.

Here’s an example of a 3D array:

                #include <stdio.h>
                int main() {
                    // Declare a 3D array with dimensions 2x3x4
                    int cube[2][3][4] = {
                        {
                            {1, 2, 3, 4},
                            {5, 6, 7, 8},
                            {9, 10, 11, 12}
                        },
                        {
                            {13, 14, 15, 16},
                            {17, 18, 19, 20},
                            {21, 22, 23, 24}
                        }
                    };

                    // Access and print elements of the 3D array
                    for (int i= 0; i < 2; i++) {
                        for (int j = 0; j < 3; j++) {
                            for (int k = 0; k < 4; k++) {
                                printf(“%d\t”, cube[i][j][k]);
                            }
                            printf(“\n”);
                        }
                        printf(“\n”);
                    }

                    return 0;
                }

Output:
1 2 3 4
5 6 7 8
9 10 11 12

13 14 15 16
17 18 19 20
21 22 23 24

In this example, int cube[2][3][4] declares a 3D array with dimensions 2x3x4, and the nested loops iterate over each element, printing its value.
