In this lab, you will replace the existing functions with more flexible ones, and you will add additional functions to perform modular tasks.
The "old" functions for displaying "hello", "goodbye", "invalid selection" and "invalid input" all do basically the same thing. They simply display a message to the user. Replace the old functions with a new function called displayMessage. The function should take a string argument, and display it.
void displayMessage(string); //prototype
The old function for displaying the menu would be more useful if it also returned the menu selection. Replace the old function with a new one called getMenuSelection that will return the menu selection as a char variable. Make sure to use the function result when you call it (assignment, display, use in expression, another function call, etc.).
char getMenuSelection(); //prototype
Wouldn't it be nice to check the menu selection for an invalid input? How about checking to see if the exit…
Change each one of these questions to now work using a function.  decide what the name of the function of each should be, how many parameters are required and what value needs to be returned. You’re no longer required to solve the problem - try to re-manage your code to be a function.
Write a program that uses input to prompt a user for their name and then welcomes
them.
Enter your name: Chuck
Hello Chuck
Some of the earliest computer games developed were Interactive Fiction games, in which the user’s environment is described in text, and the user makes choices using text commands. In this problem and the next one, we’ll be developing a very simple text-based adventure game. Every choice in this game will have exactly three options, so we can write a function that works for any of them.
Write a function selection(text, optionA, optionB, optionC), that takes in four string values. text is a string representing a prompt in a text adventure game, and optionA, optionB, and optionC are strings representing the three possible options.
The function should print out the text, and then print out the options (label them with A., B., and C.). Next, the input() function should be used to prompt the user to choose A, B, or C. Then the function should return (not print) the one character string that represents the user’s choice: 'A', 'B', or 'C'. If the user does not choose one of those…

- You are tasked with writing a small part of a museum's ticketing system. The museum calculates ticket prices using the following rules: $20.00 per admission. Children under 15 get a 50% discount. Seniors (60 years and older) get a 25% discount. Write a Python function that takes a list of customers' ages and returns the total cost for the group. Your function must match the docstring below. You do not need to include the docstring in your solution. '''Function -- get_ticket_costCalculates the cost of museum admission for a group.Parameter:group_ages -- A list of integers representing customer ages.Returns:The total cost for the group, a float. The return value is not rounded.''' Example get_ticket_cost([10, 39, 40]) returns 50.0arrow_forwardMust show it in Python: Please show step by step with comments. Please show it in simplest form. Input and Output must match with the Question Please go through the Question very carefully.arrow_forwardLook carefully at the code for your functions read_age and read_siblings. Can you see a pattern? Each of these functions prompts the user until they supply a valid integer, which is then returned. In fact, the only differences between the two functions are the prompt string for the user and a few variable names. When we find very similar blocks of code like this in a program, we should look for a single function that can do both tasks. So ... how can we generalise these functions into a single function that can be used (in two separate calls) to read both the age and the number of siblings while still printing a suitab prompt? Add a new function to your program called read_int(prompt) that takes a prompt string as input. It should use that string to prompt the user for a valid integer and then return it. Once you have done this, delete the functions read_age and read_siblings from your program and replace all calls to them with appropriate calls to you new read_int(prompt) function so…arrow_forward
- Over the years, people have created a few nicknames for me. One that sticks without me telling me to call me that name is "Denck." It works great with anyone whose name ends with an "er". We are going to create a function called "nickName" which takes in one parameter. This parameter stores the name you want to create the nickname for. If the name ends with an er, return the name with the er removed. If the name does not have an er then return the full name back to the program.arrow_forwardWrite a GO program that uses a struct that holds employee, hoursWorked, and payPerHour.

If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A = -1. The value of A should be returned by the function. Test the function by passing various data to it and verifying the returned value.arrow_forward

Include a function that displays a menu of options. All mathematical operators are to be included.arrow_forwardIN C Programming Language...THANKS The phone numbers of the companies are stored in the phones.txt. The area codes are missing in some of the phone numbers. (A phone number including area code is 10 characters). You will write a program to format phone numbers and add area code if necessary. At the end all the phone numbers will look like the following; (312) 4250204. Write the following functions; readFromFile that reads all the phone numbers from the file phones.txt into a string array. The function should return the number of phones. updateDirectory that takes the string array which keeps the phone numbers and the number of phones in the array as parameters, and updates the phone numbers adding the parentesis and area code (312) where necessary (i.e (312) 4250204). printDirectory that takes the string array which keeps the phone numbers and the number of phones in the array as parameters, and displays the number of phones and the phone list on the screen.arrow_forwardPython questionarrow_forward
