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

Something like:

auto it = foo.begin(), end = foo.end();
while ( it != end && ! bar( *it ) ) {
    ++ it;
}
if ( it != foo.end() ) {
    baz();
}

should do the trick, and it avoids the unstructured break.
