Question
Computer Science
R
Adjust your functions to take into account upper and lower case letters, as well as spaces. Bonus: can your functions also deal with special characters. Apply your first function to the variable x1 and then the second function to your output, so you can convert it back.
x1 <- "Hello My Friend"
x2 <- "This: Is, Comma: Horror!"

- Function Name: compliments Parameters: answer1 - a boolean (True or False) representing whether the user is "smart" answer2 - a boolean (True or False) representing whether the user is "awesome" answer3 - a boolean (True or False) representing whether the user is "fun" Description: Write a function that outputs a string of compliments based on the adjectives selected by the inputs. Use the inputs True and False. The function should return the string “You are” concatenated with the compliments that are true. The three compliments should be: "smart" "awesome" and "fun". If none of the compliments are true, print the string “Goodbye.” instead. Test Cases: >>>compliments(True, True, True) You are smart awesome fun. >>>compliments(False, True, False) You are awesome. >>>compliments(False, False, False) Goodbye.arrow_forwardDriving costs - functions Learning Objectives Create a function to match the specifications Use floating-point value division Instructions Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print(f'{your_value:.2f}') Ex: If the input to your program is: 20.0 3.1599 the output is: The gas cost for 10 miles is $1.58 The gas cost for 50 miles is $7.90 The gas cost for 400 miles is $63.20 Your program must define and call the driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles. Ex: If the function is called with: 50 20.0 3.1599 the function returns: 7.89975 def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon) Your program should…arrow_forwardComputer Science I need to write a program in C that allows the user to play a game of Mystery Word, here are the requirements: The program begins with a 6-letter word which is obscured by displaying an asterisk * in the place of each letter of the word. Four 6-letter words should be included in your program and have a theme. The word should be randomly selected when the user begins the game. After 7 incorrect guesses the user loses the game. The player wins by correctly guessing all of the letters that are part of the word. At each step, the program should remind the player of the letters he or she has already guessed, the program should not be case sensitive for input, but keep the output as uppercase letters. If the user enters the same letter twice that should count against them. Any help would be greatly appreciated as I'm stumped on how to complete this one.arrow_forward
