C++ Exception Handling. An exception is a problem that arises during the execution of a program. A C++ exception is a response to an exceptional circumstance that arises while a program is running, such as an attempt to divide by zero. Exceptions provide a way to transfer control from one part of a program to another.
The code which is prone to exceptions is placed in the try block, when an exception occurs, that exception occurred is handled by catch block associated with it. Every try block should be immediately followed either by a class block or finally block.he previous statements demonstrate three catch blocks, but you can have any number of them after a single try. If an exception occurs in the protected code, the exception is thrown to the first catch block in the list.
