Two-dimensional array

Question

Describe the term two-dimensional array by using example?

Answer 1

The array with two dimensions is termed as a two-dimensional array. It is as well termed as a matrix. In C, a 2-dimensional array is initialized as int arr[nb_of_rows] [nb_of_columns]. Therefore, two dimensional arrays can be considered as grid. Element in a 2-dimensional can be accessed by illustrating its row and column. If array consists of 20 integer values, it will occupy 80 bytes in memory (supposing 4 bytes for an integer). All of the bytes are in consecutive memory positions, the first row occupying the first 20 bytes, the second the next 20 and so forth.
