[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[])     { ...

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;
