Is there an equivalent to the “for … else” Python loop in C++?

Question

Python has an interesting for statement which lets you specify an else clause.

In a construct like this one:

for i in foo:
  if         


        

Answer 1

It's not only possible in C++, it's possible in C. I'll stick with C++ to make the code comprehensible though:

for (i=foo.first(); i != NULL || (baz(),0); i = i.next())
{
    if bar(i):
        break;
}

I doubt I'd let that through a code review, but it works and it's efficient. To my mind it's also clearer than some of the other suggestions.
