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 #include

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; } } return encrypted; }

string decrypt(string message, string code) { string decrypted = ""; int j = 0; for (int i = 0; i < message.length(); i++) { char c = message[i]; if (isalpha(c)) { int shift = code[j] - 'a'; char decrypted_char = (c - shift - 'A' + 26) % 26 + 'A'; decrypted += decrypted_char; j = (j + 1) % code.length(); } else { decrypted += c; } } return decrypted; }

int main() { string message, code; cout << "Enter your message: "; getline(cin, message); cout << "Enter your secret code: "; getline(cin, code); string encrypted = encrypt(message, code); // encrypt the message using the code cout << "Encrypted message: " << encrypted << endl; // print the encrypted message string decrypted = decrypt(encrypted, code); // decrypt the encrypted message using the code cout << "Decrypted message: " << decrypted << endl; // print the decrypted message cout << endl;

cout << "Enter your encrypted message: "; getline(cin, encrypted); decrypted = decrypt(encrypted, code); cout << "Decrypted message: " << decrypted << endl;

return 0; }
