Exceptionhandling oUseexception is a good way to handle errors and write a more robust program Twodifferent ways to handle exceptions oUser-definedexceptions oPredefinedexceptions may need to install a signal handler to find the catch handler oExceptionhandling may need to deallocate memory of unwinded scope
Exception handling usually requires more time and resources because it requires instantiating a new exception object rolling back the call stack and propagating the errors to the calling methods If an exception occurs in a method: If you can handle the exception in the method where it occurs there is no need to throw it

fully general implementation of the C++exception mechanism cannot rely on decorations of the stack frame passing of hidden arguments to functions not in C++ or other techniques that require compiler coop-eration for every function called Once a handler has caught an exception that exception has been dealt with and other handlers that
These are the three operators that make exception handling work throw try and catch are keywords in C++ The idea is that you create a try-block which is a statement block followed by exception handlers An exception handler is introduced by keyword catch The basic form is try {a statement sequence containing function calls to functions
The “deterministic exception” proposals tease us with hopes of healing the schism in the C++ community caused by needs for no-exception compiler options and even of finally healing the C/C++ schism To many massive efficiency improvements seem easily obtainable Others see a promise of safer and more readable code

Does C++ support exception handling?
- C++ is designed to coexist with other languages that do not support exception handling. Consequently, we rejected any ideas for exception handling that would have required all functions in a program to be writ- ten in C++. After the presentation of the exception handling scheme we discuss its use compared to ‘traditional’ error handling techniques.
What is an exception specification?
- The exception specification acts very much like a catch clause: when thethrown exception violates the exception, unwind pass 1 indicates that a han-dler was found, and pass 2 transfers control to a handler in the generatedcode.
What is an example of an exception handler?
- Consider, for example, an exception handler trying to correct an error condition by changing some state variable. Code executed in the function call chain that led from the block with the handler to the function that threw the exception might have made decisions that depended on that state variable.
How does the exception handling scheme work?
- Separate libraries assign the same values (error states) to designate different errors, thus totally con- fusing testing and handling of errors. Another way of describing the exception handling scheme is as a formalization of this way of handling errors.
