The Caesar Cipher: Privacy in communication has been an issue ever since the dawn of time. To prevent people from stealing information, we can "Encrypt" and "Decrypt" it in several ways. To encrypt something means that the message gets translated into a secret code that only the people involved can understand, decrypt is the opposite procedure. One of the oldest methods of encryption is called the Caesar Cipher Named after the dictator Julius Caesar). It consists of assigning every letter a number value and writing the word as a sequence of numbers. Consider the Caesar cipher where each character gets assigned its value in the ASCII code. a 97 b C d c с f 98 99 100 101 102 g h i 103 j k 1 104 105 106 107 108 109 11 110 0 P q r S 111 112 113 114 115 116 t 117 V 118 W 119 120 121 2122 u X y The problem is to create a C++ program that receives an encrypted message, translates it, then receives an answer from the u English and encrypts it. To do this and get full marks you are to create 5 functions, both the function prototypes and the main unction are provided. A function that reads the input array. . A function that translates the input and prints the translated message. . . A function that reads a string and returns it. hi there A function that receives a string of letters and encrypts it, returning an array. . A function that prints the answer array. Input: The first number N it receives is the length of the received code, then it receives a sequence of Nintegers. Afte translated message it should read your answer to be translated. Example: Input 5 104 101 108 108 111 1 Output M hello Assume it always receives a valid input this is N>1 all numbers in the original code are betwee 104 105 32 116 104 101 114 101
