I want to use the C++ map function, map::find, to determine if a specific string is within a map. I know that find returns map::end but I am not sure on how to use it. So if the same string exists in
Been a while since I\'ve used C++. Can I do something like this?: for (vector<Node>::iterator n = active.begin(); n!=active.end(); ++n) {
I need a class to navigate across a collection, then I implemented Iterator interface. But the problem is, my implementation of next() method need to throw an Exception, because the collection members
First of all, I\'m creating a CD-ROM based site, using Server2Go. I\'m trying to use DirectoryIterator to create a navigation bar, taken straight from my folder/file structure of .php files. Here\'s
Well, I know why, it\'s because there isn\'t a conversion, but why isn\'t there a conversion? Why can forward iterators be turned to reverse iterators but not the other way round? And more importantly
Six years ago, I burned several days trying to hunt down where my perfectly deterministic framework was responding randomly开发者_如何转开发. After meticulously chasing the entire framework ensuring t
I\'m trying to use c++ iterators with interfaces, but does not manage to make it working. I\'m a bit lost with what type to choose for the vector contents. Is this need to be a pointer ? do I have to
I am trying to use iterators more for looping since I heard it is faster than index looping. One thing I am not sure is about how to treat the end of the sequence nicely. The way I can think of is to
extern int JAX_EXP_DEBUG_print_all_exps_in_session ( ) { tag_t part_tag = NULL_TAG; for ( PART_cycle_parts_in_world ( &part_tag ); part_tag; PART_cycle_parts_in_world ( &part_tag ) )
To support STL\'s notion of half-open ranges, we are allowed to point one-past-the-end of an array. Suppose we have a vector of three elements. If std::vector::iterator is implemented as a pointer, as
