, or 2D arrays for short, are a fundamental data structure in programming. They are composed of multiple s]] and s]], which form a grid-like structure. Each within a 2D array is identified by its row and column .
of a 2D array involves declaring the array and specifying the size of its rows and columns. within a 2D array can be ed and modified using their corresponding row and column indices. of a 2D array can be done by iterating over its rows and columns, visiting each element.
in a 2D array refers to the total number of elements it holds, which is equal to the product of rows and columns. It is important to be aware of the to prevent accessing elements outside the boundary.
are an advanced concept related to 2D arrays. They allow the creation of arrays within arrays, resulting in a multidimensional structure where each element can be another array. This allows for more complex data structures with multiple levels of depth.
When working with a 2D array, each element is referenced by specifying its row and column index. The element represents the data stored within that particular location in the array structure. Row and column indices start from 0, with the first element of the array being at index [0][0].
