Question

1. Complete Programming Problem #14, Stadium Seating, on page 199 of the textbook. A revised form (original form provided in Figure 3-49) is provided below based upon theAdditional Requirements. Data is also provided to test the application.

The ADDITIONAL REQUIREMENTS described below MUST also be implemented:

• Apply the currency format string for displaying monetary output (i.e., displays a leading currency symbol, digits, comma separators, and a decimal point)

• Apply the number format string for displaying non-monetary output with no decimal places (i.e., the precision must be specified)

• Implement simple exception handling to catch any exceptions that are thrown and display the exception's default error message

• Implement named constants where applicable (i.e., the cost of the different classes of seats)

• Calculate the total tickets sold for each individual transaction

• Implement the following fields:
  • Sum of revenue which accumulates the overall revenue (i.e., running sum of the Total Revenue)
  • Sum of Tickets which accumulates the total tickets (i.e., running sum of the Total Tickets)
  • Count of Transactions which counts the number of times the Calculate Revenue button is clicked (i.e., adding to the Count of Transactions)

• Add the following Label controls to the form (Note: GroupBox controls are used to group the various TextBox and Label controls):
  • Total Tickets (descriptive and output)
  • Sum of Revenue (descriptive and output)
  • Sum of Tickets (descriptive and output)
  • Transactions (descriptive and output

This the instructions for my class and I am lost. Here is my code

CATickets = CATickets * 15.0;

Answer 1

Visual C # windows application for Stadium seating cost and revenue:

Step1:

Design the form with controls group box, labels, text boxes and buttons as shown below

Step2:

Set the properties of the controls using the below table

Step3:

Source code :

//Source code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace StadiumSeating
{
public partial class Form1 : Form
{
//declare static variables for to accumulate the transactions count
//total revenue and total tickets
private static int transactions = 0;
private static double toral_revenue = 0;
private static double total_tickets = 0;

public Form1()
{
InitializeComponent();
}

private void calRev_Click(object sender, EventArgs e)
{
//increment the transactions by 1
transactions = transactions + 1;
//Set constants for class A , class B and class C tickets cost
const double CLASS_A_COST = 15.0;
const double CLASS_B_COST = 12.0;
const double CLASS_C_COST = 9.0;
//Set A,B and C tickets to 0
int CATickets=0;
int CBTickets = 0;
int CCTickets = 0;
int totalTickets = 0;
//Set revenues of class A,B and C to 0
double classARevenue = 0;
double classBRevenue = 0;
double classCRevenue = 0;
double revenue = 0;
  
//Use try-catch block for invalid input
try
{
CATickets = int.Parse(classATicketstextBox.Text);
CBTickets = int.Parse(classBTicketstextBox.Text);
CCTickets = int.Parse(classCTicketstextBox.Text);

//Sum class A , class B and class C tickets
totalTickets = CATickets + CBTickets + CCTickets;
//accumulate the total tickets
total_tickets = total_tickets + totalTickets;
totalTicketsLabel.Text = totalTickets.ToString();

//calculate the class A, B and C revnues
classARevenue = CATickets * CLASS_A_COST;
classBRevenue = CBTickets * CLASS_B_COST;
classCRevenue = CCTickets * CLASS_C_COST;

//Set revenues of each class type
classARevenueTextBox.Text = classARevenue.ToString("C2");
classBRevenueTextBox.Text = classBRevenue.ToString("C2");
classCRevenueTextBox.Text = classCRevenue.ToString("C2");

//set revenue , total revenue
revenue = classARevenue + classBRevenue + classCRevenue;
totalRevenueLabel.Text = revenue.ToString("C2");

//Accumlate total revenue
toral_revenue = toral_revenue + classARevenue + classBRevenue + classCRevenue;

//Set total revenue, total tickets and transactions
sumofRevenueLabel.Text = toral_revenue.ToString("C2");
sumofTicketsLabel.Text = total_tickets.ToString("C2");
transactionsLabel.Text = transactions.ToString();

}
//Catch blcok
catch (Exception exception)
{
MessageBox.Show(exception.Message);
}
}
/*Double click the clear button and write below code to clear all the fields the window*/
private void clearButton_Click(object sender, EventArgs e)
{

classATicketstextBox.Text = "";
classBTicketstextBox.Text = "";
classCTicketstextBox.Text = "";

classARevenueTextBox.Text = "";
classBRevenueTextBox.Text = "";
classCRevenueTextBox.Text = "";

totalTicketsLabel.Text = "";
totalRevenueLabel.Text = "";

sumofRevenueLabel.Text = "";
sumofTicketsLabel.Text = "";
transactionsLabel.Text = "";
}

/*Double click the exit button and write below code to close the window*/
private void exitButton_Click(object sender, EventArgs e)
{
Form1.ActiveForm.Close();
}
}
}

Step4:

Save the application and run , press F5
