if I erase an element from an std::set and pass the key, not the iterator, and the key isn’t in the set right now, will an exception be thrown? The thing is every second sentence in the MSDN documentation says: “this does blah blah, but it doesn’t conform to the standard”. So I need to know the standard behaviour. I just couldn’t find it in the standard. Redirecting to the relevant clause will do as well. Thanks.

    Found this in section 23.1 (Container requirements):

    no erase(), pop_back()or
    pop_front()function throws an
    exception.

    So erase can not throw an exception.
