What is the benefit to limiting throws allowed by a C++ function? [closed]

Answer 1

The C++ standard requires that the unexpected() function is called if a function attempts to throw an exception that is not on its exception list. A short description of this from MSDN is here: http://msdn.microsoft.com/en-us/library/awbt5tew(VS.80).aspx

Most compilers do not actually support this C++ feature.
