ISC COMPUTER SCIENCE PRACTIACL 2018 QUESTION 3 TEAM BANNER STRING

/*
The names of the teams participating in a competition should be displayed on a banner vertically, to accommodate as many teams as possible in a single banner.
Design a program to accept the names of N teams, where 2 < N < 9 and display them in vertical order, side by side with a horizontal tab (i.e. eight spaces).
Test your program for the following data and some random data:
Example 1:
INPUT: N = 3
Team 1: Emus
Team 2: Road Rols
Team 3: Coyote

OUTPUT:
E        R        C     

m        o        o     

u        a         y     

s        d         o     

                     t     

         R         e     

         o               

         l               

         s               


Example 2:
Enter the number of participating teams:
5
Enter name of Team1
England
Enter name of Team2
South Africa
Enter name of Team3
India
Enter name of Team4
Australia
Enter name of Team5
Sri lanka

OUTPUT:

E        S        I        A        S     

n        o        n        u        r     

g        u        d        s        i

a        h        a        r        l     

n                          a        a     

d        A                 l        n     

         f                 i        k

ISC COMPUTER SCIENCE PRACTICAL 2018 QUESTION 2 : (MATRIX ROW SORT)

/*
 Write a program to declare a matrix A[ ] [ ] of order (M xN) where ‘M’ is the number of rows and ‘N’ is the number of columns such that the values of both ‘M’
 and ‘N’ must be greater than 2 and less than 10.
 Allow the user to input integers into this matrix. Perform the following tasks on the matrix:
(a) Display the original matrix.
(b) Sort each row of the matrix in ascending order using any standard sorting technique.
(c) Display the changed matrix after sorting each row. Test your program for the following data and some random data:
