How is a multi-dimensional array stored in the memory?

Explanation:

A multi-dimensional array is a data structure that allows the storage of data in a grid or table-like format, making it possible to organize data in multiple dimensions (e.g., 2D, 3D). The most common form of multi-dimensional arrays are two-dimensional (2D) arrays, which can be visualized as a matrix with rows and columns.

Correct Option: Row-wise (Row-major order)

In most programming languages, multi-dimensional arrays are stored in memory in a row-major order. This means that the elements of the array are stored one row at a time. For example, consider a 2D array:

A[2][3] = {
    {1, 2, 3},
    {4, 5, 6}
};

In row-major order, this array would be stored in memory as follows:

1, 2, 3, 4, 5, 6

This storage format has significant implications for how we access and manipulate multi-dimensional arrays in memory. When accessing elements in a row-major order, the memory addresses of the elements are contiguous for a given row, which can lead to better cache performance and more efficient memory access patterns.
