C Multidimensional Array

Multidimensional Array :

1. Array having more than one subscript variable is called Multi-Dimensional array.
2. Multi Dimensional Array is also called as Matrix.

Consider the Two dimensional array -

1. Two Dimensional Array requires Two Subscript Variables
2. Two Dimensional Array stores the values in the form of matrix.
3. One Subscript Variable denotes the “Row” of a matrix.
4. Another Subscript Variable denotes the “Column” of a matrix.

Declaration and Use of Two Dimensional Array :

int a[3][4];

Use :

for(i=0;i<row,i++)
   for(j=0;j<col,j++)
   {
   printf("%d",a[i][j]);
}

Meaning of Two Dimensional Array :

1. Matrix is having 3 rows ( i takes value from 0 to 2 )
2. Matrix is having 4 Columns ( j takes value from 0 to 3 )
3. Above Matrix 3×4 matrix will have 12 blocks having 3 rows & 4 columns.
4. Name of 2-D array is ‘a‘ and each block is identified by the row & column number.
5. Row number and Column Number Starts from 0.
