13.7. Error and Exception Handling

Try these first

1. 1.

   What method does C++ use to check failed file operations?

   Hint

   Think about the functions associated with streams.

2. 2.

   In which programming language would you encounter FileNotFoundError?

   Hint

   Remember the error handling concept in Python.

3. 3.

   Which method is used to check for file stream failure in C++?

   • read()
   • fail()
   • close()

   Hint

   Consider the operations available for file streams.

4. 4.

   True or False: In Java, exceptions are handled using the try-catch block.

   • True
   • False

   Hint

   Reflect on how exceptions are managed in Java.

5. 5.

   Create a C++ program that attempts to open a non-existent file and utilizes the fail() method to handle the exception effectively.

   Hint

   Focus on checking the state of the file stream after attempting to open it.

6. 6.

   Write a Java program snippet that retrieves a file's contents and uses a try-catch block to catch an exception if the file is missing.

   Hint

   Think about how to use the structure for graceful failure.
