Caesar Encryption

Write a C function that computes and prints the Caesar encryption of a string with an offset of n. The Caesar encryption replaces each letter of the message with the one n places later in the alphabet. For letters at the end of the alphabet, the offset wraps around to the beginning of the alphabet.

As arguments, the function obtains and the character string to be encrypted. You may assume that the string only contains the ASCII symbols a-z.

What is different from and what is similar to an implementation in assembly?
