What are various types of arrays? Explain them
Arrays can of following types:
1. One dimensional (1D) arrays or Linear arrays
2. Multi dimensional arrays
(a) Two dimensional (2D) arrays or Matrix arrays
(b) Three dimensional arrays
1. One dimensional (1D) arrays or Linear arrays:
In it each element is represented by a single subscript. The elements are stored in consecutive memory locations. E.g. A [1], A [2], ….., A [N].
2. Multi dimensional arrays:
(a) Two dimensional (2D) arrays or Matrix arrays:
In it each element is represented by two subscripts. Thus a two dimensional m x n array A has m rows and n columns and contains m*n elements. It is also called matrix array because in it the elements form a matrix. E.g. A [2] [3] has 2 rows and 3 columns and 2*3 = 6 elements.
(b) Three dimensional arrays:
In it each element is represented by three subscripts. Thus a three dimensional m x n x l array A contains m*n*l elements. E.g. A [2] [3] [2] has 2*3*2 = 12 elements.
