- Develop a single program using any programming language (e.g. Java, Python, C++, etc.) that:a. Encrypts and decrypts a message using the Cesar’s Cipher. The user encryptingthe message is prompted to enter a message and then a key that indicates the displacement.The user decrypting the message is prompted to enter the encrypted message and the key.b. Decrypts and displays all (26) possible solutions.Write a c program in which you ask from user to that you want to open a account or want to change passwordWrite a c++ code that takes run time live price of Bitcoin and Ethereum from internet and then stores it in a string and prints it
- a. Write Java classMessage that automatically gives each created Message object a unique serial number, starting at 1 for the first message. (Hint: static) b) Write statements that create three Message objects. Show and explain serial numbers for these objects.Write a program in c++ that asks you to enter a 5 digit password all at one time. The program then displays the password back to the user.Create a C++ address book using the following information: The address should contain a Person class. string firstName; string middleName; string lastName; Each person’s detailed address should be provided as follows: int block; int unit; int floor; string street; string city; string country; int postalCode; Write appropriate getters/ setters and test your implementation.
- Write a C++ program that converts a string of a positive number into a numeric format. You are required to create this conversion using a stack. The conversionshould accommodate both decimal numbers and numeric numbers.This is for c++. I need a program that leads a person through the steps of fixing a bad Wi-Fi connection.Write a C++ program that takes a number N as input, and prints a sequence of numbers. The first term in this sequence should be N. The second term should be calculated using the following scheme: If the term is even, the next term is N/2. If the term is odd, the next term is 3N+1. The third term is calculated from the second term using the same scheme. The fourth term is calculated from the third term using the same scheme, and so on. You should stop when the last term you have printed is 1. Your code should also print the total number of terms in the sequence. (Use While loop)
