Single File Programming QuestionProblem 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 :vNote :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.Marks : 10Negative Marks : 0

Solution
To solve this problem, you can use the ASCII values of the characters. Here is a step-by-step guide on how to do it in C:
- First, you need to include the necessary libraries. In this case, you need the stdio.h library for input and output functions.
#include <stdio.h>
- Then, declare the main function.
int main() {
- Inside the main function, declare a character variable to store the input character and an integer variable to store the shift amount.
char c;
int n;
- Use the scanf function to get the input from the user.
scanf("%c %d", &c, &n);
- Now, check if the input character is a lowercase or uppercase letter. If it is, perform the shift operation. If it's not, print the character as it is.
if(c >= 'a' && c <= 'z') {
c = ((c - 'a' + n) % 26) + 'a';
} else if(c >= 'A' && c <= 'Z') {
c = ((c - 'A' + n) % 26) + 'A';
}
printf("%c", c);
- Finally, return 0 to indicate that the program has finished successfully.
return 0;
}
Here is the complete code:
#include <stdio.h>
int main() {
char c;
int n;
scanf("%c %d", &c, &n);
if(c >= 'a' && c <= 'z') {
c = ((c - 'a' + n) % 26) + 'a';
} else if(c >= 'A' && c <= 'Z') {
c = ((c - 'A' + n) % 26) + 'A';
}
printf("%c", c);
return 0;
}
This program works by shifting the ASCII value of the input character by the specified amount. The modulo operation ensures that the shift wraps around the alphabet.

Alice and Bob want to communicate securely over an insecure channel where Evecould be listening. To ensure their message remains confidential, they decide to usea simple substitution cipher for encryption and decryption, where each letter in thealphabet is shifted by a fixed number of places.For this exercise, use a shift of 3 places to the right (a Caesar Cipher). For example,'A' becomes 'D', 'B' becomes 'E', 'Z' becomes 'C', and so on. Spaces and punctuationare not encoded; they remain unchanged.Alice wants to send the following message to Bob: "HELLO WORLD".a. Encrypt Alice's message using the specified shift.
