e Write a program that produces a Caesar cipher of a given message string. A Caesar cipher, or rotation cipher, is formed by rotating each letter of a message by a given amount. For example, if you rotate by 3, every A becomes D; B becomes E; and so on. Toward the end of the alphabet, you wrap around: X becomes A; Y becomes B; and every Z becomes C. Your program should prompt for a message and an amount by which to rotate each letter and should output the encoded message. Your message? Attack zerg at dawn Encoding key? 3 Your message: DWWDFN CHUJ DW GDZQ

How to create a Caesar cipher program with the given rules?
### Caesar Cipher Program Explanation

This document describes a program that creates a Caesar cipher, which is a type of substitution cipher. In a Caesar cipher, each letter in the plaintext is shifted a certain number of places down or up the alphabet. 

**Details:**

- **Program Functionality**: The program prompts for a message and a numerical key for the cipher.
- **Encoding Process**: Each letter in the message is rotated by a specified amount (given by the key). For example, with a key of 3:
  - 'A' becomes 'D'
  - 'B' becomes 'E'
  - 'C' becomes 'F'
  - As the end of the alphabet is reached, it wraps around: 'X' becomes 'A', 'Y' becomes 'B', and 'Z' becomes 'C'.

**Example Given:**

- **Original Message**: "Attack zerg at dawn"
- **Encoding Key**: 3
- **Encoded Message**: "DWWDFN CHUJ DW GDZQ"

The document also includes graphical data that appears unrelated to the main text about the Caesar cipher. This data consists of a matrix of numbers with no clear context provided.
