Question

Non-member template functions always have parameters. True False The correct implementation for a post-decrement operator for a doubly linked list iterator is (done as an inline function) node_iterator operator-(){ node_iterator original("this): current = current rightarrow previous(): return original: } node_iterator operator--(int){ node_iterator original("this): current = current rightarrow previous(): return original: } node_iterator operator --(int){ node_iterator original ("this): current = current rightarrow previous(): return original: } node_iterator operator-(int){ node_iterastor original = current: current = current rightarrow current rightarrow next(): return original: } node_iterator operator --(int){ current = current rightarrow previous(): return 'this: } A linked list consists of an array of elements. an infinite set of nodes. a finite set of nodes. an abstract ordering of elements.

Explanation / Answer

Question 21

Non-member template functions always hava parameters

Answer: True

Explanation :

A non-template class can have template member functions,the template function must have a different

template parameter identifier.

Question 22

The correct implementation for a post-decrement operator for a doubly linked list iterator is( done as an inline

function)

Answer: Option

b) node_iterator operator --(int) {
node_iterattor original(*this);
current=current->previous();
return original;
}

Question 23

Answer: Option c) a finite set of nodes

Explantion:

A linked list is a finite sequence of nodes each of which contains a pointer field pointing to the next node
