can you do it in c++

In cryptography, a Caesar cipher, also known asCaesar's cipher, the shift cipher, Caesar's code for Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. Given an arbitrary cipher text file, you need to write a C++ program to find out the value of the shift, and decrypt the ciphertext to plaintext. You must not hard code the cipher text nor any shift values in your program. Test your program with a sample cipher text here (only the alphabetic letters are changed): Submit the following: 1. Source code 2. A screen shot showing the execution of the program and the correct offset value 3. The output plaintext file Encrypt this: Ty ncjaezrclasj, pyncjaetzy td esp acznpdd zq eclydqzcxtyr tyqzcxletzy (cpgpccpo ez ld awltyepie) fdtyr ly lwrzctesx (nlwwpo ntaspc) ez xlvp te fycplolmwp ez lyjzyp pinpae eszdp azddpddtyr dapntlw vyzhwporp, fdflwwj cpqpccpo ez ld 1 vpj.
