Caesar Chiper

Simple implementation of the Caesar Cipher encryption and decryption algorithm. The Caesar Cipher is a substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet.

Prerequisites

To compile and run this project, you need a C++ compiler such as GCC or Clang.

Compilation

To compile the project, use the following command:

g++ -o caesar_cipher main.cpp

This will create an executable file named caesar_cipher.

Running the Program

To run the compiled program, use:

./caesar_cipher

Input

Enter the text you want to encrypt. Enter the shift value (an integer) for the Caesar Cipher.

Output

The program will display:

• The encrypted text based on the provided shift value.
• The decrypted text, which should match the original input text.

Example

Enter the text: Hello World
Enter the shift: 3
Encrypted text: Khoor Zruog
Decrypted text: Hello World
