Lab 6.1.1 creating and printing arrays let's work on some basic skills by creating a program that contains a few experiments with arrays. if you are asked to print out a value, be sure to print a label that indicates what the value represents, unless otherwise indicated. for example, if you are asked to print a variable z, the output might look like this: z : 8.0 perform each of the following tasks: a) create an array x of doubles with an initializer list that contains the following values: 8, 4, 5, 21, 7, 9, 18, 2, and 100. b) print the number of items in the array by printing the expression x. length. c) print the first array item, x[0]. d) print the last array item. be careful to choose the right index. e) print the expression x[x. length - 1]. why is this value the same as in part d? f) use a standard for loop to print all the values in the array without labels. g) use a standard ( loop to print all the values in the array with labels to indicate what each element is. h) use a standard for loop to print all the values in the array in reverse order with labels to indicate what each element is. i) use an enhanced for loop to print all the values in the array without labels.

Write a method public static string getdigits(string phonenumber) that takes an 11-character phone number written with any combination of 11 uppercase letters, lowercase letters and/or digits, and zero or more hyphens, and which returns the digits that a person would have to press on a cell phone to dial that phone number. we will use the mapping of letters to digits given at en.wikipedia.org/wiki/telephone_keypad# /media/file: telephone-keypad2.svg you may assume that the string parameter phonenumber contains some combination of exactly 11 uppercase letters, lowercase letters and/or digits, but that any number of hyphens may be present. you can assume that a hyphen will not appear as the first or last character of the string. do not assum
