Program Plan Intro
Seating in Theatre
Program Plan:
- Include header file section.
- Declare the global constants for number of rows and columns
- Declare the function prototypes.
- Inside main() function,
- Declare the required variables for theater seating.
- The outer for loop executes until the number of rows fails and the inner for loop executes until the number of columns fails.
- Prompt the user to enter the ticket price for each row.
- Use the do…while loop to display the menu options available using displayMenu() function.
- Inside the loop, use the switch…case expression to select the case based upon the user choice.
- If the user choice is “1”, then call the function displaySeats() to display the number of seats.
- If the user choice is “2”, then call the function displayPrices() to display the seat prices.
- If the user choice is “3”, then call the function displaySales() to display the total number of sales.
- If the user choice is “4”, then call the function purchaseTicket() to display the number of tickets purchased.
- If the user choice is “5”, then exit from the program.
- If the user enters the choice other than 5, then while loop executes until the user enters correct choice.
- In function displayMenu(),
- Print the header with available menu options.
- In function getChoice(),
- Validate the choice entered by the user. If validation fails, ask the user to re-enter the choice.
- In function displaySeats(),
- This function uses two for loops to print the theater seating with sold and available tickets on theatre.
- In function displayPrices(),
- This function uses two for loops to print the ticket prices for each row.
- In function purchaseTicket(),
- Prompt the user to enter the input “yes” or “no” to view the seating details of chart.
- Convert the input to uppercase and call the function displaySeats() to display number of seats in theatre.
- Use do..while loop to enter the desired row number.
- Validate using while loop whether the entered row number is from 1 to 15. Otherwise ask the user to re-enter the input.
- Validate using while loop whether the entered seat number is from 1 to 30. Otherwise ask the user to re-enter the input.
- The if condition validates whether the seat is marked with “#” or “*”.
- If the seat is market with “#” then the seat is available print the user with the message “purchase confirmed”.
- Calculate the patron’s ticket total and total price of tickets that has been sold.
- If the seat is market with “*” otherwise the seat is taken by some other user.
- Display the total price of tickets.
- In function displayPrices(),
- This function prints the total sales upto the current date.

This program should be designed and written by a team of students. Here are some suggestions: o One student should design function main, which will call the other functions in the program. The remainder of the functions will be designed by other members of the team. o The requirements of the program should be analyzed so each student is given about the same work load. o The parameters and return types of each function should be decided in advance. o The program can be implemented as a multi-file program, or all the functions can be cut and pasted into the main file. Here is the assignment: Write a program that can be used by a small theater to sell tickets for performances. The theater’s auditorium has 15 rows of seats, with 30 seats in each row. The program should display a screen that shows which seats are available and which are taken. For example, the following screen shows a chart depicting each seat in the theater.

The functions will be contained in two files: Functions.h, which contains the function prototypes, and Functions.cpp, which will contain the function implementations (or bodies). Do not forget to put include guards in the Functions.h file. Begin the program by declaring variables and then calling the function WriteHeader. This function will display your name, the program title and objective. Then call ShowRules, which explains the rules. See the random number generator function. This is only done once. Call AskForName to get the player’s name. This functions returns a string with the player’s name. Open a do while or while loop. This is the “play loop,” which allows the user to play craps as many times as he/she wants. Call the function AskForBet to retuun the amount of the user’s bet.

Pointer Tasks This part of the assignment will give you a chance to perform some simple tasks with pointers. The instructions below are a sequence of tasks that are only loosely related to each other. Start the assignment by creating a file named pointerTasks.cpp with an empty main function, then add statements in main() to accomplish each of the tasks listed below. Some of the tasks will only require a single C++ statement, others will require more than one. For each step, include a comment in your program indicating which step you are completing in the following statement(s). The easiest way to do this is copy and paste the below into your main function first, and then fill in your statements. // 1. Create two integer variables named x and y// 2. Create an int pointer named p1// 3. Store the address of x in p1// 4. Use p1 to set the value of x to 99// 5. Using cout and x, display the value of x// 6.

This program requires functions. Place the function prototypes in a file named FallFunctions.h. Create a global constant for ACCELERATION in the .h file, too. Use a comment to define the units for acceleration. Place the associated function implementations in FallFunctions.cpp. Call all functions from main, which is located in your Driver.cpp. In main, you will call the Header function first. Then, start a do another loop. Inside the loop, call the AskHeight function using a reference to height to ask the user for the height of the fall in feet. Next, call the TimeToFall function using a pointer to time to calculate the time it takes the object to fall.

This is the final program which will be included in the portfolio. To get the highest mark the game should be as close as possible to the game described below. You will need to: use arrays and determine how to ensure that a card which is dealt to one user is removed from the pack so that it is not available to other users. make the program user friendly. Rules of the game At the start of a blackjack game, the players and the dealer will receive two cards each. The players' cards are normally dealt face up, while the dealer has one face down (called the hole card) and one face up. The aim of the game is to accumulate a higher point total than the dealer, but without going over 21. You compute your score by adding the values of your individual cards. The cards 2 through 10 have their face value, J, Q, and K are worth 10…arrow_forwardURGENT: Python Expense Management: This system will add, deduct, update, sort, and export expenses to a file.
