Write a program that displays the cost of diﬀerent options at a vending machine. Your program must: • read in a selection char from a ﬁle called input.txt, • use case statements to select the price linked to the input char, • write the price corresponding to the char to a ﬁle called output.txt. • If the char is not present in the ﬁle write -1 to the ﬁle. You should account for all items as listed in Table 4 as well as invalid selections (those not listed in table 4).

In C++ please, using basic programming one coding The main menu should show the available options: Show the roster: Displays all the player names and jersey numbers in a numbered list. Ex: 1. Susan Martinez (33), 2. Jake Smith (21), etc. Add a player: Prompts the user to type the player's full name and jersey number. Then adds the player to the roster. Remove a player: Displays the roster and prompts the user to enter the number of the player to remove. Then removes the player from the roster. Quit: Quits the program. The program should display the main menu after the user shows the roster, adds a player, or removes a player. The program only terminates when the user chooses the quit option. Data validation should be used where appropriate. Ex: The user should not be able to choose an option that doesn't exist or delete a player that doesn't exist. The roster should be kept in alphabetic order by the players' full names. Ex: If Alice Chang (9) is added to a roster with Jake Smith and…

The Barking Lot is a dog day care center. Write a program that accepts data for an ID number of the dog's owner, and the name, breed, age, and weight of the dog. Display a bill containing all the input data as well as the weekly day care fee, which is $55 for dogs under 15 pounds, $75 for dogs from 15 to 30 pounds inclusive, $105 for dogs from 31 to 80 pounds inclusive, and $125 for dogs over 80 pounds.
In this exercise you will write a program for printing out grade statistics for a university course. The program asks the user for results from different students on the course. These include exam points and numbers of exercises completed. The program then prints out statistics based on the results. Exam points are integers between 0 and 20. The number of exercises completed is an integer between 0 and 100. The program kees asking for input until the user types in an empty line. You may assume all lines contain valid input, which means that there are two integers on each line, or the line is empty. And example of how the data is typed in: Exam points and exercises completed: 15 87 Exam points and exercises completed: 10 55 Exam points and exercises completed: 11 40 Exam points and exercises completed: 4 17 Exam points and exercises completed: Statistics: Sample output
Write a program that prompts the user to enter a Bill line (Product name, quantity, unit price, and discount value). The program will then: Calculate the total of row: Total = quantity + unit price • Calculate the total after discount: total after discount = total – discount Apply a VAT tax of 12% and find the net: net = total after discount * (1 + tax) The program will then display all the information needed as shown in the sample run below Sample Run: Enter the name of the product: Keyboard Enter the quantity: 4 Enter the price of the Keyboard (in $): 10 Enter the discount rate %: 5 The total after discount is: 38 The net of 4 ( Keyboard ) is: $42.18
Using C++ For each game played you will write the final results for the player and the computer. The data written should look like this: 19 21 18 23 21 16 You will have the player data first, a tab '\t', and then the computer result followed by a newline '\n' So, in the example above, in the first game, the player got 19 and the computer got 21. In the second game, the player got 18 and the computer got 23. After the player stops the program, you will close the writing file stream and open the input file stream of the newly created file. Read each line of numbers and calculate: The average result of the player for all the games played. The average result of the computer for all the games played. The total wins for the player and the computer. Then, declare who is the best 21 player! The output from above will look like this assuming the computer is named, "Ruby." Your game average was 19.3 Ruby's game average was 20.0 You won 2…

In Python Text-based adventure game: Pretend you are creating a text-based adventure game. At different points in the game, you want the user to select to fight, run, or hide from certain enemies. The selection variable must be sent as an argument into the choice() function. The user should enter 1 to fight, 2 to run, or 3 to hide in the main(). The choice() function should print one of the three options. Add an if statement in the choice() function to make the correct selection.

A game program contains the following code to update three score variables, health, food, and knowledge. The maximum values for the three variables are 100, 80, and 25, respectively. The game program’s author would like to write a procedure that could be used to update any variable in the game (myScore) that has a maximum value (myLimit) by a given amount (myAmount). A correct call of the procedure is shown below. Which of the following is a correct implementation of updateScore ? 4 answer options in picture below, full question in other pic
A student took four quizzes in a term and would like to compute their average. He also would like to know what will be the remarks. Follow the range of grades and its equivalent remarks, and then fill-up the table below: 100-95 - Excellent 94-90 – Very Satisfactory 89-85 - Satisfactory 84-80 - Fine 79-75 - Fair 74 and below – Poor *CREATE THE EQUIVALENT FLOWCHART ANSWER THIS QUESTIONS What are the data needed for the solution of the program to produce the desired output? What statements in the program that determine the average grade remarks? What have you observed in using switch statement in this program than using if-else statement?
In order for a player to navigate your game, you will need to develop a function or functions using Python script. Your function or functions should do the following: Show the player the different commands they can enter (such as “go North”, “go West”, and “get [item Name]”). Show the player’s status by identifying the room they are currently in, showing a list of their inventory of items, and displaying the item in their current room. You could make these separate functions or part of a single function, depending on how you prefer to organize your code. Sample function showing the goal of the game and move commands def show_instructions(): #print a main menu and the commands print("Dragon Text Adventure Game") print("Collect 6 items to win the game, or be eaten by the dragon.") print("Move commands: go South, go North, go East, go West") print("Add to Inventory: get 'item name'") The blue image is an example of how the code should look. The map image is the map your code should…
