Question 2: Encryption is a process to secure your data. Caesar Cipher is one of the method to encrypt the data. In this method we need a key to encrypt data. Now using that key one character is replaced with another one. [small or capital alphabets are allowed, otherwise invalid input] Write a C++ program in which, read a character and an integer key from user. Now encrypt the character using given key. Example 1: Sample input: Enter a character: a Enter key: 3 Sample output: Encrypted character is: d Example 2: Sample input: Enter a character: Z Enter key: 3 Sample output: Encrypted character is: C Example 3: Sample input: Enter a character: @ Enter key: 3 Sample output: Invalid input
