Two Dimensional Array

Two dimensional array (2-D array) is also called Matrix

General form of 2-D array is:

data_type array_name[row_size][column_size];

Example:

int marks [4][2]

Different ways of Initialization of a 2-Dimensional Array:

int table [2][3]={0,0,0,1,1,1};

initialization done by row.

int table[2][3]={{0,0,0},{1,1,1}};

surrounding the elements of each row by braces.

int table[2][3]={{0,0,0,},

initialization as matrix.

An example program that stores roll number and marks obtained by a student side by side in Matrix:

Explanation

There are two parts of the program. In the first part a for loop will read the values of rollno. and marks, whereas in the second part another loop will print these values.
