Can someone help me solve this using c++

The Caesar cipher, also known as a shift cipher, is one of the classic form of encryption that were used historically. Each letter in the original message (plaintext) is replaced with a letter corresponding to a certain number of letters up or down in the alphabet. In this way, a message that initially was quite readable, ends up in a form that cannot be understood at a simple glance. For example, here is the Caesar Cipher using a right rotation of 5 places (equivalent to a left shift of 21 places). The shift parameter is used as the key Plain ABCDEFGHIJKLMNOPORSTUVWXYZabcdefghijklmnopqrstuvwxyz Cipher: FGHIJKLMNOPQRSTUVWXYZABCDEfghijklmnopgrstuvwxyzabcde Obviously, if a different key is used, the cipher alphabet will be shifted a different amount. When encrypting, looks up each letter of the message in the "plain" line and writes down the corresponding letter in the "cipher" line. The example below uses the key 5 Plaintext:Procedural Programming vs Object Oriented Programming Ciphertext: Uwthjizwfq Uwtlwfrrnsl ax Tgojhy Twnjsyji Uwtlwfrrnsl The Caesar Ciphe follows. r can be represented using modular arithmetic as Enc(x) (x +n) mod 26 This means that the encryption of a letter x is equal to a right shift of x by n letters. The result of the process is then taken under modulo division, meaning that if a letter is shifted past the end of the alphabet, it wraps around to the beginning. Now, you are given below a cipher text "Fhewhqccydw qdt shofjewhqfxo qhu vkd. Oek sqd tushofj jxyi cuiiqwu kiydw rhkju vehsu qijqsa. Sxusa qbb feiiyrbu auoi kdjyb jxu sehhusj edu yi vekdt" Where the period () and comma () symbols are not encrypted. Write a program to decrypt this message by exhaustively search over all possible 26 keys. (Hint: Declare a character array and initialize it with the given Ciphertext, i.e encrypted using Caesar Cipher. int cipher Fhewhqccydw qdt shofjewhqfxo qhu vkd. Oek sqd tushofj jxyi cuiiqwu kiydw rhkju vehsu qijqsa. Sxusai qbb feiiyrbu auoi kdjyb jxu sehhusj edu yi vekdt. Then write a loop to shift the ciphertext array element-by-element.)
