Syntax of C++ Exceptions
C++ exceptions allow the programmer to change the flow of control when some event occurs, for example, an error. These errors happen at run time (file is not found, index is invalid, etc.); when C++ raises an exception, the program may terminate if it has no handler that knows how to deal with that exception.
Exception handlers are segments of program source code that should be executed when the exception is raised, for example, printing a message to the user, collecting information for the analysis of the causes of the exception, or error recovery.
Organizing error-related source code into exception handlers can make flow of control more logical; instead of doing all the tests in the mainline of the algorithm and thus ...
