Multi-dimensional Arrays
The types of arrays discussed so far are all linear arrays.
That is, they all dealt with a single dimension.
But think about a situation where we want to store elements of a 3x4 matrix.
The C language allows to have multi- dimensional arrays for this kind of situations. 

3. 2 Dimensional Arrays - 2D Also called as 2D arrays.
2 Dimensional Arrays - 2D
Column Index No.
Also called as 2D arrays.
Take the example of the 3x4 matrix. To store the elements of this we can declare a 2D array as follows:
int matrix[3][4]; 1 2 2 6 9 4 5 12 10 16 7 3 18
Raw Index No.
Raw Column

4. Assigning Values to a 2D Array Elements
Example 1: You can refer by row column indices
int matrix[3][4];
matrix[0][0] = 2;
matrix[0][1] = 6;
Example 2: You can initialize row wise
int matrix[3][4] = { {2,6,9,4},
{5,12,10,16},
{7,3,3,18} };

5. Array Exercise
Declare a 2D array and store the values shown in the figure.
Read the elements from the user
After storing all the values, display the content of the matrix.
Column Index No. 1 2 2 6 9 4 5 12 10 16 7 3 18
Raw Index No.

Homework
Write a program to read values for a 2x3 matrix from a user and multiply with a scalar value and display the result. The scalar value also you must read from the user.
Write a program to multiply two matrices of integers. 1st matrix is 3x2 and the 2nd matrix is 2x4. Display the result.
Note : No need to read the matrices values from the user
