Question

My question is pretty vague :o) – But here is an example :

When I was writing C code, I was able to log counter’s value when something failed :

   <...>    for ( int i = 0 ; i < n ; i++ )       if ( SUCCESS != myCall())          Log( 'Failure, i = %d', i );    <...> 

Now, using exceptions, I get this :

  try    {       <...>       for ( int i = 0 ; i < n ; i++ )          myCall();       <...>    }    catch ( Exception exception )    {       Log( 'Failure ! Maybe in myCall() ? Don't know. i's value ? No clue.' );    } 

Of course, one may declare ‘i’ outside of the try/catch statement (and this is what I’m doing). But I don’t like it – I like declare variable where they are used, not before.

But maybe am I missing something here. Do you have any elegant solution ?

Thank in advance ! Sylvain.

ADDED : myCall() is an obscure API call – I have no clue what it can throw. Also, I can of course add a Try/Catch block around each call, but I would then be better to use return codes ? Would I then add a lot of noise around important lines of code ?.

how about:

for(int i = 0; i < n; i++) {   try   {     myCall();   }   catch(Exception e)   {     Log(String.Format('Problem with {0}', i));   } }
