![i need help fixing my program so that the user can input both uper and lower case letters
Write a new C++ program named Vigerene.
use the rules of this website Code.org to return the message
Code.org (Links to an external site.)
Write the C++ program, Vigerene, which will prompt the user for a string message and a string
secret code. The code must be shorter than the message. Then write a function which takes the
message and code as parameters, and converts the two strings into a encrypted code using the
rules on the code.org website. Return the encrypted message and print it in the Main class.
Now write a new function which takes in an encrypted message and a secret code as two
parameters and decrypts the the message and returns it to Main for printing.
Here is sample output:
Enter your messge: my name is rick
Enter your secret code: helloworld
TBKYOHSQTVGVTNY
Enter your encrypted message
TBKYOHSQTVGVTNY
MY NAME IS RICK
code:
#include <iostream>
#include <string>
using namespace std;
string encrypt(string message, string code) {
string encrypted = "";
int j = 0;
for (int i = 0; i < message.length(); i++) {
char c = message[i];
if (isalpha(c)) {
int shift = code[j] - 'a';
char encrypted_char = (c + shift - 'a') % 26 + 'A';
encrypted += encrypted_char;
j = (j + 1) % code.length();
}
else {
encrypted += c;](https://image.slidesharecdn.com/ineedhelpfixingmyprogramsothattheusercaninputbothuperand-230314165718-a08b091b/85/i-need-help-fixing-my-program-so-that-the-user-can-input-both-uper-and-pdf-1-320.jpg)
