This is my third time posting the question, and i got two answers before that were copied from other sites and they're wrong. Please write C++ code for this question, show the steps, Please don't just paste the asnwer from the other wrong sites. Thanks

Please help writting a code using C++ ONLY. Please show the steps and comment thanks in advance i i Let K be a fixed element of Z26, and define the fixed permutation over Z26 as 0 12 3 45 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 23 13 24 0 7 15 14 6 25 16 22 1 19 18 5 11 17 2 21 12 20 4 10 9 38 Z26, where zi = (K + i Consider the strain cipher with the key streami element zi decryption using are done as follows: 1) mod 26, Encryption and e:(z) = ((z) + z) mod 26, d, (y) = (-1(y-z) mod 26) Write a C/C++program streamCipher to decrypt the following ciphertext which was encrypted by the above stream WRTCNRLDSAFARWKXFTXCZRNHNYPDTZUUKMPLUSOXNEUDOKLXRMCBKGRCCU RR Your program should use brute force attack and stop when the user is satisfied with the result.
