[Question 5] ICSE 2016 Computer Application Solved - Pattern

-

Question 5.

Using the switch statement, write a menu driven program for the following:
(i) To print the Floyd’s triangle [Given below]
1
2  3
4  5  6
7  8  9  10
11 12 13 14 15
(ii) To display the following pattern
I
I C
I C S
I C S E
For an incorrect option, an appropriate error message should be displayed.

SOURCE CODE


import java.io.*;
class ICSE2016_Ques5_Pattern
{
    public static void main(String args[])throws IOException
    {
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Press 1 to print Floyd's triangle");
        System.out.println("Press 2 to print second pattern");
        int n=Integer.parseInt(br.readLine());
        switch(n)
        {
            case 1:
            System.out.print("Enter a number  :");
            int m=Integer.parseInt(br.readLine());
            int a=1;
            for(int i=1;i<=m;i++)
            {
                for(int j=1;j<=i;j++,a++)
                {
                    System.out.print(a+" ");
                }
                System.out.println();
            }
            break;
            case 2:
            System.out.print("Enter a word  :");
            String st=br.readLine();
            int l=st.length();
            for(int i=0;i<l;i++)
            {
                for(int j=0;j<=i;j++)
                {
                    System.out.print(st.charAt(j));
                }
                System.out.println();
            }
            break;

            default:
            System.out.println("Wrong choice");
        }
    }
}

[Question 3] ISC 2017 Computer Practical Paper Solved – Caesar Cipher.

Question 3: Caesar Cipher  is an encryption technique which is implemented as ROT13 (‘rotate by 13 places’). It is a simple letter substitution cipher that replaces a letter with the letter 13 places after it in the alphabets, with the other characters remaining unchanged. Write a program to accept a plain text of length L, where L must be greater than 3 and less than 100. Encrypt the text if valid as per the Caesar Cipher. Test your program with the sample data and some random data: Example 1 INPUT :  Hello! How are you? OUTPUT :  The cipher text is: Uryyb? Ubj ner lbh? Example 2 INPUT :  Encryption helps to secure data. OUTPUT :  The cipher text is: Rapelcgvba urycf gb frpher qngn. Example 3 INPUT :  You OUTPUT :  INVALID LENGTH SOURCE CODE    import java.io.*; import java.util.*; public class ISC2017_CaesarCipher {     public static void main(String args[])     {         Scanner sc=new Scanner(System.in);         System.out.pri

Pattern of your own name.

Pattern program of your own name. This is a pattern program, in this program you just have to enter your name and it will give you output in a particular manner. I have created this program when I was in class 10th for my Computer Application project. NOTE:  If you are copying my code then its a advise to you to copy it after downloading it to avoid any kind of compilation error its link is available at the bottom of source code. SOURCE CODE import java.io.*; public class Patter_of_your_Own_Name { public static void main(String args[])throws IOException { int time=1; BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); do { System.out.print("\n\t\t\tPLEASE,ENTER YOUR GOOD NAME IN CAPITAL LETTER           :"); String str=br.readLine(); int flag=0;
