Question
What is the ciphertext of "software" using a shift cipher (key = 5)?
Solution
To encrypt the word "software" using a shift cipher (also known as Caesar cipher) with a key of 5, follow these steps:
-
Write down the alphabet and then write it again below, but shifted by 5 places. It should look like this:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z F G H I J K L M N O P Q R S T U V W X Y Z A B C D E
-
Now, for each letter in "software", find it in the top row and replace it with the letter in the bottom row.
S -> X O -> T F -> K T -> Y W -> B A -> F R -> W E -> J
-
Put these letters together to get the ciphertext. So, "software" encrypted with a shift cipher of 5 is "XTKYBFWJ".

Problem StatementGeorge, a secret agent, needs a program to encrypt a character using a shifting method. The program should prompt him to enter an alphabet and a shift amount as register storage class inputs. The encrypted character is obtained by shifting the input alphabet by the specified amount in a circular manner. Uppercase and lowercase letters wrap around, ensuring a seamless shift within the alphabet.Example: If the character 'y' wants to be rotated 6 times, it wraps around the alphabet after reaching 'z'. The shifting process results in the output 'e'.Input format :The input consists of a character c representing the alphabet on which shifting happens and an integer n representing the number of times it has to be shifted, separated by a space.Output format :The output prints the character after shifting the input alphabet (to its right) n times.If c is not an alphabet, the output prints the input character as such without shifting.Refer to the sample output for the formatting specifications.Code constraints :In the given scenario, the test cases fall under the following constraints:c should be a valid ASCII character.1 ≤ n ≤ 20Sample test cases :Input 1 :A 1Output 1 :BInput 2 :Z 2Output 2 :BInput 3 :c 4Output 3 :gInput 4 :y 6Output 4 :eInput 5 :# 5Output 5 :#Input 6 :b 20Output 6 :v
