If we want to get or set the value for that variable that we have to need de-referenced that it means we need to get memory location where it is actually placed in the memory. NULL) throw std::invalidargument('Attempt to dereference end()'). We use reference to store the address to variable or object. The Constructor The KW::list::iterator constructor takes as a parameter a pointer to. The end () iterator can be used to mark the end of a range - you can't dereference it however using operator, and I suspect your code is doing something similar to that. This leads to undefined behaviour, possibly a crash. If you are declaring a local variable as an object then it will be allocated in the heap area. I created a list added an int, and attempted to dereference the end () iterator. And objects always allocates on the heap area. The primitive data types variable considered as local variables or as a field. The primitive data is different from objects because they do not behave as objects. In Java programming, there are two different types of variables: primitive data type and object type.
