Defining Multidimensional Arrays in C programming

Defining Multidimensional Arrays in C

In C programming, a multidimensional array is an array of arrays. It allows you to store data in a table-like format. The most common type of multidimensional array is the two-dimensional array, but C supports arrays with more dimensions as well.

Syntax

The general syntax for defining a multidimensional array is:

data_type array_name[size1][size2]...[sizeN];

Here, size1, size2, ..., sizeN specify the number of elements in each dimension.

Example

Here is an example of defining and initializing a two-dimensional array:

#include <stdio.h>

int main() {
    // Defining a 2x3 multidimensional array
    int arr[2][3] = {
        {1, 2, 3},
        {4, 5, 6}
    };

    // Accessing and printing elements of the array
    for (int i = 0; i < 2; i++) {
        for (int j = 0; j < 3; j++) {
            printf("arr[%d][%d] = %d\\n", i, j, arr[i][j]);
        }
    }

    return 0;
}

Explanation

• int arr[2][3]; - Declares a two-dimensional array with 2 rows and 3 columns.
• { {1, 2, 3}, {4, 5, 6} } - Initializes the array with values.
• The nested for loops are used to access and print each element of the array.

Note: You can define arrays with more than two dimensions. For example, a three-dimensional array would be defined as data_type array_name[size1][size2][size3];.
