This program encrypts confidential messages using Caesar's cipher by shifting each letter by a specified number of places. The key, provided as a command-line argument, determines the number of shifts. The user then inputs the plaintext to be encoded, and the program outputs the enciphered text.
Usage: ./caesar (key)
Note: This program only executes with a single command-line argument (the key).
This program was created for my CS50's problem set 2.
