ISC COMPUTER SCIENCE PRACTICALS 2009 BOUNDARY ELEMENTS

Write a program to declare a matrix A[ ][ ] of order (m*n) where 'm' is the number of rows and
n is the number of columns such that both m and n must be greater than 2 and less than 20.
Allow the user to input positive integers into this matrix. Perform the following tasks on the
matrix:
(a) Sort the elements of the outer row and column elements in ascending order using any
standard sorting technique.
(b) Calculate the sum of the outer row and column elements.
(c) Output the original matrix, rearranged matrix, and only the boundary elements of the
rearranged array with their sum.
Test your program for the following data and some random data.
1. Example :
INPUT : M=3, N=3
1 7 4
8 2 5
6 3 9
OUTPUT :
ORIGINAL MATRIX :
1 7 4
8 2 5

REARRANGED MATRIX :

BOUNDARY ELEMENTS :

ISC COMPUTER SCIENCE PRACTICAL 2009 DAY NUMBER

Design a program to accept a day number (between 1 and 366), year (in 4 digits) from the user
to generate and display the corresponding date. Also accept 'N' (1<=N<=100) from the user to
compute and display the future date corresponding to 'N' days after the generated date.
Display error message if the value of the day number, year and N are not within the limit or
not according to the condition specified. Test your program for the following data and some
random data.

Example:

INPUT : DAY NUMBER : 233 YEAR : 2008 DATE AFTER(N) : 17
OUTPUT: 20TH AUGUST 2008 DATE AFTER 17 DAYS : 6TH SEPTEMBER 2008
INPUT : DAY NUMBER : 360 YEAR : 2008 DATE AFTER(N) : 45
