In your preferred programming language, write a program that will ask the user to enter any plaintext. Then, it will encrypt/decrypt that string using Caesar Cipher and prints out
the results on the screen. In this time, the user will not be asked to enter any keys,
encryption should be based on the following conditions:
a. Replace the characters at the odd positions by the previous character in the alphabet.
b. Replace the characters at the even positions by the next 3 character in the alphabet

Which statistical function in a spreadsheet you to see how far each number varies, on average, from the average value of the list?

File account. java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
