some peculiar problems other than logic or syntax error are known as C++ exceptions.
Exceptions error are run-time anomalies or unusual condition that a program may enchanter while executing.
Anomalies night include condition such as division by ‘0’, access to an array outside of its bounce or running out of memory or disk space .
Types of c++ exceptions
There are two types of exception
- Synchronous exception
- Asynchronous exception
Errors such as out of range index and over flow belong to the synchronous type exception.
The errors that are lost by event beyond the …….. of the program such as key board interrupt are called asynchronous.
Exception handling mechanism
C++ exception handling mechanism is basically built upon 3 key words namely
The keyword try is used to preface a block of statement which may generate exceptions.
Dis-block of statements is known as try block.
When an exception is detected it is thrown using a throw statement in the try block.
A catch block defined by the key word catch catches the exception thrown by the throw statement in the try block and handles it appropriately.
