I'm really ashamed!<br />
<br />
I have to talk to my boss! I do too little programming<br />
nowadays and too much report writing. I have to get back to the real business, i.e. programming!<br />
<br />
Well, easy earned points. Sorry AlexFM, I let the points go to jkr since he posted his answer 4 minutes before you.<br />
<br />
Thanks, <br />

I'm trying to figure out how exception handling works in C++.<br />
<br />
Example: <br />
class A {};<br />
class B : A {};<br />
class C : A {};<br />
<br />
void f()<br />
{<br />
&nbsp; try<br />
&nbsp; {<br />
&nbsp; &nbsp; throw C();<br />
&nbsp; }<br />
&nbsp; catch (B&amp; b)<br />
&nbsp; {<br />
&nbsp; }<br />
&nbsp; catch (A&amp; a)<br />
&nbsp; {<br />
&nbsp; }<br />
}<br />
<br />
I had the impression that in this example, the exception would be caught in 'catch (A&amp; a)', since A is a base class to C. It doesn't. I'vr tried both in MS Visual C++ and on HP C++ (on a UNIX machine). Both programs behave bad. Do any one out there know how the exception handling should be handled in this case?<br />
<br />
Thanks.

C++ exception handling wrt class hierarchy

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
