C++ In a Nutshell

<exception>

The <exception> header declares classes, types, and functions related to fundamental exception handling. See <stdexcept> for additional exception classes.

Note

This section describes a complicated system of exceptions, function calls, and handlers. The end result is simpler than it might seem at first:

A function can throw only the exception types listed in its exception specification, or else the program terminates immediately.

If a function does not have an exception specification, it can throw any exception. (Virtual functions work a little differently; see Chapter 6 for details.)
