How to Encode and Decode Using the Vigènere Cipher

VIDEO solution: Using the C programming language, implement a Caesar cipher. Only use stdio.h and stdlib.h. Ask the user for a single lowercase letter (a - z) to start their cipher alphabet. Then ask the user to enter a single word (no spaces, all lowercase) to encipher, with a maximum length of 50 characters. Assume that the user will obey this limit and never enter a word larger than 50 characters. Print the cipher alphabet, plaintext word, and cipher word to the screen.It should look like thi
