One to traverse the rows and another to traverse columns.Sorry, but we are currently blocking access to our site.ġ.) We have detected an unusual amount of improper or excessive behavior such as using our site to compile business lists, company information, accumulate sales leads, etc. To output all the elements of a Two-Dimensional array we can use nested for loops. Therefore, for row index 2 row number is 2+1 = 3. Note: In arrays, if the size of an array is N. The above example represents the element present in the third row and second column. In the above example, there is a total of three rows so there are three sets of inner braces.Īccessing Elements of Two-Dimensional Arrays: Elements in Two-Dimensional arrays are accessed using the row indexes and column indexes. Each set of inner braces represents one row. This type of initialization makes use of nested braces.

Initializing Two – Dimensional Arrays: There are two ways in which a Two-Dimensional array can be initialized. A two – dimensional array ‘x’ with 3 rows and 3 columns is shown below:

A two – dimensional array can be seen as a table with ‘x’ rows and ‘y’ columns where the row number ranges from 0 to (x-1) and column number ranges from 0 to (y-1).

Elements in two-dimensional arrays are commonly referred to by x where i is the row number and ‘j’ is the column number.

We can declare a two-dimensional integer array say ‘x’ of size 10,20 as:.

The basic form of declaring a two-dimensional array of size x, y:ĭata_type array_name data_type: Type of data to be stored.

We can see a two – dimensional array as an array of one – dimensional array for easier understanding. Two – dimensional array is the simplest form of a multidimensional array. Similarly array int x can store total (5*10*20) = 1000 elements. The array int x can store total (10*20) = 200 elements. The total number of elements that can be stored in a multidimensional array can be calculated by multiplying the size of all the dimensions.
