Replace “Another manipulator, setprecision, is used to set the precision...Combining these three manipulators finally achieves the desired result:” with:

When the next value is displayed, it is padded with spaces so that the total width is 8. For example,

cout << setw(8) << 34.95;

yields

···34.95

(where each · represents a space).

When lining up currency values, you also need to control the number of digits after the decimal point. For example, you want 34.5 to display as 34.50 and 34.249997 as 34.25.

Another pair of manipulators, fixed and setprecision, is used for this purpose.

The command

cout << fixed << setprecision(2);

ensures that subsequent floating-point numbers are printed with two digits after the decimal point.

Combining these three manipulators achieves the desired result:

Otherwise, go to the right child if there is one, or to the leftmost descendant of the next unvisited parent otherwise.” to “If the current node has a right child, then go to the leftmost leaf of the right child. Otherwise keep moving up to the parent until the previously traversed node is a left child.”

Repeat for 12 push_back operations and an initial buffer size of 10.”
