Understanding the Difference Between Multidimensional Array and Nested Array

When it comes to arrays in computer programming, there are two concepts that are often confused - multidimensional arrays and nested arrays. Let's clarify the difference between the two:

Multidimensional Array:

A multidimensional array is an array that contains other arrays. In simple terms, it is an array of arrays. This allows for the storage of data in multiple dimensions, such as rows and columns.

Nested Array:

A nested array, on the other hand, is an array within an array. This means that the elements of the outer array are themselves arrays. In other words, a nested array is a one-dimensional array that contains other arrays as its elements.

Key Differences:

1. Structure: A multidimensional array is an array of arrays, while a nested array is an array within an array.
2. Usage: Multidimensional arrays are used for storing data in multiple dimensions, while nested arrays are useful for organizing data in a hierarchical structure.
3. Access: Elements of a multidimensional array are accessed using multiple indices, while elements of a nested array are accessed by chaining array indexes.

So, in summary, while both multidimensional and nested arrays involve nested structures, the key difference lies in the way data is organized and accessed within them.
