Instrucfions To implement Assignment 1, you need to follow the following instruction: - Students need to choose a suitable programming language - Students need to write the code, compile, and run the program. - Students need to submit the complete source code and output of the program Tasks: 1. Caesar cipher is one of the classical substitution ciphers which replaced the letters of plaintext with other letters to form the ciphertext. Write a program to implement the Caesar cipher where the user can input the plaintext "This is a plaintext that will be converted into the ciphertext using Caesar cipher" and the key for encryption. The program should display the encrypted message. 2. Rail fence cipher is one of the classical transposition ciphers that arranged the letters of plaintext in form of a "zig-zag" and read the letters row by row to form the ciphertext. Write a program to decipher the ciphertext "HVEEEENLOROLY" when the key is 4. Deliverables Submit the complete source code and output of the program
