Chapter 7, Problem 49RQE

Program Plan Intro

Two-dimensional array with row and columns:

A two dimensional array is otherwise called as 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 type of value where as two dimensional array 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.

Example:

//Declaring multi-dimensional array

double testmarks[5][5];

The above statement is used to create a two dimensional array with “5” rows and “5” columns; the first square bracket is used to refer the number of rows and the second square bracket is used to refer the number of columns.
