Complete Modern C++ - File IO - Part II (Error Handling)

The video tutorial covers handling errors in stream IO operations, focusing on the use of stream state flags such as good bit, bad bit, fail bit, and EOF bit. It explains how these flags indicate the state of a stream and how to use them to manage errors during file operations. The tutorial also discusses handling critical errors and managing state flags using functions like clear and set state. The video concludes with a preview of the next tutorial, which will focus on creating a text file copying utility.

What function is used to check if a file is successfully opened in stream IO?

• stream_verify

• open_status

• file_check

• is_open

Which stream state flag indicates that there is no error in the stream?

• EOF bit

• good bit

• fail bit

• bad bit

What does the fail bit indicate in stream IO operations?

• End of file reached

• A critical error occurred

• An IO operation failed

• The file is open

When is the EOF bit set during stream IO operations?

• When end of file is reached

• When an IO operation fails

• When a file is opened

• When a critical error occurs

What does the bad bit signify in stream IO?

• End of file reached

• A recoverable error

• No error in the stream

• A critical error that cannot be recovered

How can you reset the state flags of a stream?

• Using the reset function

• Using the clear function

• Using the refresh function

• Using the initialize function

Which function allows setting a specific state in stream IO?

• flagset

• stateconfig

• setflag

• setstate
