Encryption Program

This is a simple encryption and decryption program implemented in C++ that demonstrates how to apply a basic encryption algorithm. The program uses a key-based system to encrypt and decrypt user-inputted strings.

Features

• Encryption: The program encrypts the user's input string by adding a key value to each character's ASCII code.
• Decryption: The program decrypts the encrypted string by subtracting the key value from each character's ASCII code.
• Key Algorithm: A simple algorithm using a constant key value generated by a mathematical expression (pow(2, 2 * 5 / 4)).

How it works

1. User Input:

   • The program prompts the user to input a string or password that they want to encrypt.

2. Encryption:

   • The Encryptionvar function takes the input string and the encryption key (calculated as pow(2, 2 * 5 / 4)).
   • Each character of the string is modified by adding the key value to its ASCII code.

3. Decryption:

   • The Decryption function takes the encrypted string and subtracts the same key value from each character's ASCII code to retrieve the original string.

4. Key Calculation:

   • The key is calculated using the expression pow(2, 2 * 5 / 4), which results in the key value 16.
