say I have code
try
{
....
}
catch()
{
.... // exception occur here ... how to handled.
}
Is there any mechanism in c++ by which the above scenario can be handled.

3Wrap it in a `try`/`catch`...? – Biffen Nov 18 '14 at 08:38

7By making sure that you don't have any code that can throw an exception in the exception handler? – Some programmer dude Nov 18 '14 at 08:39

1If you don't know what to do with the exception, let your caller handle it. – n. m. could be an AI Nov 18 '14 at 08:50

If there's a need to do thing like that then it shows flaw in your deign – ravi Nov 18 '14 at 09:08

1Yes, there are several mechanisms. You can put a `try` inside the `catch` block, you can nest `try` blocks, you can use a re-throw (`throw;` with no subexpression), you can save an `exception_ptr`, you can use `nested_exception`. We need more info to guide you in a particular direction. – Potatoswatter Nov 18 '14 at 09:08

If you think this is what you really want, you can do it like this:
try
{
try
{
//...
}
catch( ... )
{
//...
if( .. )
throw std::runtime_exception( "error occured" );
}
}
catch( std::runtime_exception& e )
{
// handle exception of exception handler
}

@Nihar: You could also put a try-catch block into the `catch( ... )`-body: `try{ } catch( ... ){ try{ } catch( ... ) }` – Raoul Steffen Nov 18 '14 at 12:52
