c programme

Your task is to design automated solvers for the shift and Vigen`ere ciphers. You must use C as the underlying programming language, in order to get prepared for the following assignments. Each solver should be completely automated, i.e., upon reading a text file containing the target ciphertext (given as command-line argument), it should print the encryption key and the decrypted plaintext without any user interaction. Test your code on the following ciphertexts, and answer these questions:

(a) What is the key of the cipher?

(b) What is the decrypted plaintext?
