Question
Chapter 22, Problem 22.15E
Program Plan Intro
To list various type of exceptional conditions that have occurred throughout this text and how the program would handle the exceptions.
Expert Solution & Answer
Explanation of Solution
S. No. | Exception | Exception Handling |
1. | Division by Zero | This exception is handled by defining a catch handler.
Using a try block, the denominator can be verified. If it is zero, the program throws an exception. The catch block catches the exception and informs the user. |
2. | Out-of-range array subscripts | A catch- handler can handle this exception. The code can be placed in a try block. If an error occurs, the exception can be caught by the catch block. |
3. | Arithmetic flow | The code is place in the try block.
If any value exceeds the maximum value permitted, the exception can be thrown. The catch block will catch this exception and print this. |
4. | Arithmetic underflow | Similarly, if any value is lesser than the permitted minimum value, the exception can be thrown by the try block and can be caught by catch block. |
5. | Invalid function parameters | This exception indicates the invalid argument(s) to any function from which it is thrown. This too is handled by using catch block. |
6. | Unsuccessful memory location | This exception is generated when the ‘new’ operator fails to allocate a memory. To handle this exception, place the code in a try block and catch the exception when error is recorded and validated. |

Students have asked these similar questions
In a few well-written paragraphs, discuss the use of exceptions and exception handling in programming. Your discussion should include definitions for exception, exception handler, throw signal, and catch process. Discuss why exceptions are helpful for handling runtime errors, such as division by zero.
Part 1
Describe how catching exceptions can help with file errors. Write a Python example that implements exception handling for any one of the file errors. Your code should use, try: except: blocks. Clearly mention the exception name in except block that you would handle. Include the code and output in your post along with necessary explanation.
Part 2
Describe how you might deal with a file error if you were writing a large production program. These descriptions should be general ideas in English, not actual Python code.
The code and its output must be explained technically whenever asked. The explanation can be provided before or after the code, or in the form of code comments within the code. For any descriptive type question, Your answer must be at least 150 words.
Remember to post your initial response as early as possible, preferably by Sunday evening, to allow time for you and your classmates to have a discussion.

2. Create a program of your own choice and show
a. The use of try-catch-finally block for exception handling.
b. The use of throw keyword for exception handling.
c. The use of throws keyword for exception handling.
