- C++ error handling often involves checking for errors after each operation, which can clutter code.
- Exceptions offer a cleaner approach by allowing functions to throw errors and handle them elsewhere.
- Exceptions can make constructors that fail more manageable, eliminating the need for two-phase initialization.
- Performance concerns about exceptions are often based on outdated information; modern implementations are efficient.
- A major drawback of exceptions in C++ is the lack of explicit documentation in function signatures about what can be thrown.
- Java's approach to exceptions (checked vs. unchecked) provides a model for categorizing recoverable vs. unrecoverable errors.
- Exceptions can make code more concise and readable compared to alternatives like std::expected or error codes.
- The C++ community's reluctance to adopt exceptions widely may stem from historical performance myths and lack of compiler enforcement.
