What is the primary goal of error handling?

  1. To prevent errors from occurring

  2. To detect errors when they occur

  3. To recover from errors when they occur

  4. To ignore errors when they occur


Correct Option: B
Explanation:

Error handling is the process of detecting, recovering from, and preventing errors in a computer program.

Which of the following is not a common type of error?

  1. Syntax errors

  2. Runtime errors

  3. Logical errors

  4. User errors


Correct Option: C
Explanation:

Logical errors are not a type of error in a computer program. They are errors in the logic of the program, which can cause the program to produce incorrect results.

What is the most effective way to prevent errors from occurring?

  1. Use a high-level programming language

  2. Write clear and concise code

  3. Test the program thoroughly

  4. Use error-handling techniques


Correct Option: B
Explanation:

Writing clear and concise code is the most effective way to prevent errors from occurring. This makes it easier to identify and fix errors when they do occur.

Which of the following is not a common error-handling technique?

  1. Try-catch blocks

  2. Throw statements

  3. Assert statements

  4. Ignore errors


Correct Option: D
Explanation:

Ignoring errors is not a common error-handling technique. It is generally considered to be bad practice, as it can lead to unexpected results.

What is the purpose of a throw statement?

  1. To raise an exception

  2. To catch an exception

  3. To handle an exception

  4. To prevent an exception


Correct Option: A
Explanation:

A throw statement is used to raise an exception. This means that it signals that an error has occurred, and that the program should stop executing.

What is the purpose of a try-catch block?

  1. To prevent errors from occurring

  2. To detect errors when they occur

  3. To recover from errors when they occur

  4. To ignore errors when they occur


Correct Option: C
Explanation:

A try-catch block is used to recover from errors when they occur. It allows the program to continue executing after an error has occurred.

What is the purpose of an assert statement?

  1. To prevent errors from occurring

  2. To detect errors when they occur

  3. To recover from errors when they occur

  4. To ignore errors when they occur


Correct Option: B
Explanation:

An assert statement is used to detect errors when they occur. It checks a condition, and if the condition is false, it raises an exception.

Which of the following is not a good practice for error handling?

  1. Use descriptive error messages

  2. Log errors to a file

  3. Ignore errors

  4. Use error-handling techniques


Correct Option: C
Explanation:

Ignoring errors is not a good practice for error handling. It can lead to unexpected results and make it difficult to debug the program.

What is the best way to handle user errors?

  1. Display a clear and concise error message

  2. Allow the user to retry the operation

  3. Log the error to a file

  4. All of the above


Correct Option: D
Explanation:

The best way to handle user errors is to display a clear and concise error message, allow the user to retry the operation, and log the error to a file.

Which of the following is not a common type of user error?

  1. Mistyping

  2. Misunderstanding the instructions

  3. Entering invalid data

  4. All of the above


Correct Option: D
Explanation:

Mistyping, misunderstanding the instructions, and entering invalid data are all common types of user errors.

What is the best way to prevent user errors from occurring?

  1. Use clear and concise instructions

  2. Provide examples and tutorials

  3. Validate user input

  4. All of the above


Correct Option: D
Explanation:

The best way to prevent user errors from occurring is to use clear and concise instructions, provide examples and tutorials, and validate user input.

Which of the following is not a good practice for preventing user errors?

  1. Use jargon and technical terms

  2. Use unclear and ambiguous instructions

  3. Provide insufficient examples and tutorials

  4. All of the above


Correct Option: D
Explanation:

Using jargon and technical terms, using unclear and ambiguous instructions, and providing insufficient examples and tutorials are all bad practices for preventing user errors.

What is the best way to handle errors that occur in a thread?

  1. Use a try-catch block

  2. Use a throw statement

  3. Use an assert statement

  4. All of the above


Correct Option: A
Explanation:

The best way to handle errors that occur in a thread is to use a try-catch block.

Which of the following is not a good practice for error handling in a thread?

  1. Use a try-catch block

  2. Use a throw statement

  3. Use an assert statement

  4. Ignore errors


Correct Option: D
Explanation:

Ignoring errors is not a good practice for error handling in a thread. It can lead to unexpected results and make it difficult to debug the program.

What is the best way to handle errors that occur in a process?

  1. Use a try-catch block

  2. Use a throw statement

  3. Use an assert statement

  4. All of the above


Correct Option: A
Explanation:

The best way to handle errors that occur in a process is to use a try-catch block.
