Two-dimensional array: A two dimensional array is also called as a multi-dimensional array; a multidimensional array is that all the identical arrays are put together into a single array. This is useful for storing same type of multiple sets of data in same place. The main advantage is that one-dimensional array can hold only one set of value, whereas, two-dimensional array can hold multiple sets of data in the form of rows and columns. The structure of a multi-dimensional array is lookalike a table (that is combination of rows and columns); it contains same type of columns. The first size declarator in the two-dimensional array represents row and the second size declarator represents column. The two dimensional array can have multiple length fields, which holds the number of rows. Each row in the two dimensional array has a length field which holds the number of columns. Syntax: The syntax of two dimensional arrays is as follows: datatype array_name [number_of_rows][number_of_columns]; From the given syntax, a two-dimensional array named “grades” of type “int” has been created with 30 rows and 10 columns.

Two-dimensional array:

A two dimensional array is also called as a multi-dimensional array; a multidimensional array is that all the identical arrays are put together into a single array.

This is useful for storing same type of multiple sets of data in same place.

The main advantage is that one-dimensional array can hold only one set of value, whereas, two-dimensional array can hold multiple sets of data in the form of rows and columns.

The structure of a multi-dimensional array is lookalike a table (that is combination of rows and columns); it contains same type of columns.

The first size declarator in the two-dimensional array represents row and the second size declarator represents column.

The two dimensional array can have multiple length fields, which holds the number of rows.

Each row in the two dimensional array has a length field which holds the number of columns.

Syntax:

The syntax of two dimensional arrays is as follows:

datatype array_name [number_of_rows][number_of_columns];

From the given syntax, a two-dimensional array named “grades” of type “int” has been created with 30 rows and 10 columns.
