An array of arrays can be defined as a two-dimensional array. The matrices that make up the 2D array are represented as a collection of rows and columns. 2D arrays, on the other hand, are used to build a data structure that resembles that of a relational database.
A two-dimensional array is identical to a one-dimensional array, except it looks like a grid (or table) with rows and columns. Horizontal and vertical reference numbers are used to reference positions in a two-dimensional array, much like a map.
C for Software Engineering:
A two-dimensional array is a collection of homogenous components that are arranged in a number of rows and columns. The term "matrix" refers to a collection of rows and columns. The elements and data are kept in a tabular format.
Accessing Elements in Two-Dimensional Arrays: Row and column indexes are used to access elements in two-dimensional arrays. Example: int x[2][1]; The element in the third row and second column is represented by the above example.
Use the new keyword, followed by a space, the type, the number of rows in square brackets, and the number of columns in square brackets to construct an array, such as this new int[numRows][numCols]. In a 2D array, the number of rows times the number of columns equals the number of elements.
