Write a function cipher(plaintext, n) to shift all characters in a string of text. Your function should take 2 parameters, the plaintext to shift (a string) and the shift key n (an integer). Set up an accumulator variable (suggested name: ciphertext) in which to accumulate the result. Use a definite loop with the accumulator pattern to go through all characters in plaintext.

Create a string list. 2. use console. readline() to collect values of firstname, lastname, street, city, state, zip, save them to list. 3. write a simple linq statement, call method uppercasewords() to change first letter to uppercase. 4. create a foreach statment to display the information. public static string uppercasewords(string value) { char[] array = value. tochararray(); if (array. length > = 1) { if (char. islower(array[0])) { array[0] = char. toupper(array[0]); } } for (int i = 1; i < array. length; i++) { if (array[i - 1] == ' ') { if (char. islower(array[i])) { array[i] = char. toupper(array[i]); } } } return new string(array);
