In Cryptography, encyption is defined C= E(M), where M is theplaintext, C is the associated ciphertext, and E() is theencrpytion function. When assuming a key K, a naive definition forCaesar cipher encryption would be C = E(M) = (M+K), but it actuallydoes work well for some messages, Correct the encyptionfunction.
Similarly, a naive decryption function, M = D(C) = C-K, does notwork perfectly. Correct the decryption function.
