CBSE Class 12 Computer Science Arrays Worksheet

Arrays

1. An array A[10][20] is stored in memory with each element requiring 2 bytes of storage. If the base address of array in the memory is 400 , determine the location of A[5][10] when array is stored in
(a) Row Major order
(b) Column Major order

2. Write a user defined function named New() which takes a two dimensional array as an argument and the output shows all zeroes in the upper half.

For eg if the array entered is
      6       3       2       1       8
      9       4       7       9       3
A=  5      7       0       5       3
      6       9       3       2       1
      7       5       4       3       9

The output will be -----
0       0       0       0       0
9       0       0       0       0
5       7       0       0       0
6       9       3       0       0
7       5       4       3       0
