Question

How

would you dereference the following iterator and print its content
to the screen followed by a newline?

Nodelist:
:Iterator it;

Answer 1

To dereference an iterator named 'it' and print its content, use the dereference operator (*) and output stream operator (<<) followed by a newline character.

Step-by-step explanation:

To dereference the iterator it and print its content to the screen followed by a newline in the context of a Nodelist, you would typically use the dereference operator (*) in conjunction with the output stream operator (<<). The code snippet to achieve this would look something like this:

std::cout << *it << '\\';

This statement first dereferences the iterator it to access the value that it points to. Then it prints that value to the standard output using std::cout. The '\\' is a newline character which ensures that the next thing printed to the screen will appear on a new line.
