PROJECT 4
Now that you’ve completed the material related to Chapters 10 and 11 of your textbook, you’re ready to complete Graded Project 4. For this graded project, you’ll use many of the C# skills you’ve learned thus far. Follow all the instructions for this graded project, and follow good programming practices as you create your solution. Remember to include all the required components when you submit your solution.
Instructions
To finish this graded project, which is based on Exercise 6a on pp. 537–538, you must complete a number of tasks to create the necessary solution. You’ll create a ■ BookException class
■ A Book class
■ A program that establishes several Book objects and handles any thrown exceptions
Note: To complete this graded project, use a text editor or use Microsoft Visual C# software. The figures included in this graded project show the steps involved when using the Visual C# integrated development environment (IDE). The IDE adds extra code, so if you choose to create your program using a text editor instead of the IDE, the code may be slightly different. When you’re finished, be sure to run your program to make sure it works. Remember: Always run your program after you complete the code to make sure it works appropriately.
Part A
Begin this graded project by completing these steps:
1. Start a new C# project named BookExceptionDemo.cs.
2. Save the BookExceptionDemo.cs program in Chapter.11 folder in your Student files (Figure 10).

Part C
After creating a Book class, complete these steps: 1. Create a program that establishes several Book objects and handles any throw BookExceptions. Refer to pp. 522–524 of your textbook.
2. Save your program.
3. Now build your program by selecting Build from the menu bar (Figure 11). Your program will automatically build. Any errors that could occur in the code will typically be shown at the bottom of your screen.
4. After you’ve built your program, test your program by selecting Debug > Start Debugging from the menu bar (Figure 12). Your program will execute and display results. If any errors occur during the execution of your program, you’ll be prompted and taken back to your code so you can make corrections.
5. If necessary, continue Steps 3 and 4 in Part C until your program works as intended.
