The output of the preceding program is as follows:
Enter element in 1st array: 23
Enter element in 1st array: 36
Enter element in 1st array: 31
Enter element in 1st array: 0
Enter element in 1st array: 2
Enter element in 2nd array: 25
Enter element in 2nd array: 36
Enter element in 2nd array: 32
Enter element in 2nd array: 31
Enter element in 2nd array: 25
Merged Array is: 23 : 36 : 31 : 0 : 2 : 25 : 36 : 32 : 31 : 25 :
11.8 DOUBLE-DIMENSIONAL ARRAY
A double-dimensional array or 2D array is a type of array which is used when we need to refer to data, stored in a
tabular form. In this tabular format, data are stored in horizontal and vertical form and are known as rows and columns
respectively.
st
So, a double-dimensional array uses a combination of rows and columns, where the 1 index refers to the row
nd
position and the 2 index refers to the column position. It is also known as the double subscripted value as it has
2 subscripts.
Let us understand this concept with the following example.
C O L U M N
0 1 2 3 4
R 0
O 1 44
W 2
3 67
