Exception Handling
Exception Handling Concepts
Separate normal program flow from error handling.
Errors are reported to a calling environment via exceptions.
Key Mechanisms:
throw to signal an exception.
try block to detect potential errors.
catch blocks to handle specific exceptions.
Throwing and Catching Exceptions
Syntax:
throw <exception_object>;
catch (<type> <var>) { }
Catch block types:
Specific (e.g., catch(int e))
Generic (catch(...))
Exception Classes
Custom exception classes can categorize errors.
May include:
Type information.
Data members for error-specific details.
Traditional Error Handling
Error Sources: Division by zero, invalid input, memory allocation failure, etc.
Use return values or global error variables.
Frequent error checks in code.
