Caesar cipher is one of the earliest known and simplest ciphers. It is a type of substitution cipher in which each letter in the plaintext is 'shifted' a certain number of places down the alphabet. For example, with a shift of 1, A would be replaced by B, B would become C, and so on.
INPUT
first line of input is N denoting the number of shifts to be done
second line of input is the text to be ciphered
OUTPUT
encoded message
CONSTRAINTS

If you only want to shift letters in range A-Z a-z, then mine is not for you 😢, anyway take a look 😀.

This was written in c, then modified to accept input in the c++ code playground.
It will also accept the shift as first input or from the command line (not both) if built using a compiler.
Also first command line argument is a d then it will decide, ie the shift is in the other direction.
