The illustration shows a code segment with the lines numbered from 25 through 33 and the annotations are as follows:

"cout << "Two steps forward and one step back:\n";
 p++;
 cout << *p << endl;
 p++;
 cout << *p << endl;"
" p--;" annotated as "This is the decrement operator. It works for any bidirectional iterator."
 "cout << *p << endl;
 return 0;
 }"
