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

Example:

//Declaring multi-dimensional array

The above statement is used to create a multidimensional array with “5” rows and “5” columns; the first subscript (that is square bracket) is used to refer the number of rows and the second subscript is used to refer the number of columns.

The data type “double” represents that the array will hold only “double” type of data.

The “testmarks” array can hold 25 elements (that is 5 × 5 = 25 ).

Array declaration:

Consider the given statement,

//Declare the two-dimensional array

double sales[6][4];

The above code illustrates that the declaration of a two dimensional array named “sales” which holds “6” rows and “4” columns; so totally the array can hold “24” elements (that is 6×4=24 ).

The index number representation for the “24” elements are as follows:

Column 1 Column 2 Column 3 Column 4
Row 1 (0, 0) (0, 1) (0, 2) (0, 3)
Row 2 (1, 0) (1, 1) (1, 2) (1, 3)
