3 cards from this section. Quick, good the night before a test.
What does the fail() method do in C++?
Think about what happens when an attempt to open a file fails.
How would you check for errors after reading from a file in C++?
Recall how the stream state can affect your operations.
What method would you use to check if the last I/O operation failed?
It shares its purpose with diagnosing failures in operations.
True or False: The bad() method indicates a minor error in file operations.
Consider the severity of stream errors.
Write a C++ program that opens a file and includes error handling for both access failure and critical stream errors. Include comments explaining your code.
Handle both types of errors separately after trying to perform file operations.
Design a scenario where it would be important to check both for fail() and bad() while streaming data. Explain your answer.
Consider transitional states during I/O operations where errors can arise.
