Question
Chapter 12, Problem 12.17E
Program Plan Intro
Program plan:
- line, token variables are used for input. There is structure Treenode having data, leftptr, rightptr member variables which represent the tree node.
- void insertnode(node **ptr, char *value) function inserts the node in the tree.
- void preorder(node *ptr) function displays the contents of the tree in a preorder fashion.
- void inorder(node *ptr) function displays the contents of the tree in an in-order fashion.
- void postorder(node *ptr) function display the contents of the tree in a post-order fashion.
Program description:
The main purpose of the program is to create a tree from the line entered by the user and split it into the word. Then these words are inserted into the tree. This created tree contents are displayed in preorder, inorder and postorder fashion.

Methods (Ch6) - Review
1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java.
There are two methods, method #1 which calculates the square root for positive integers, and
method #2, which calculates the square root of positive doubles (also works for integers).
public class SquareRoot {
public static void main(String[] args) {
}
// implement a loop of your choice here
// Method that calculates the square root of integer variables
public static double myRoot(int number) {
double root;
root=number/2;
double root old;
do {
root old root;
root (root_old+number/root_old)/2;
} while (Math.abs(root_old-root)>1.8E-6);
return root;
}
// Method that calculates the square root of double variables
public static double myRoot(double number) {
double root;
root number/2;
double root_old;
do {

root (root_old+number/root_old)/2;
while (Math.abs (root_old-root)>1.0E-6);
return root;
}

- Write a C++ program that will count from 1 to 10 by 1. The default output should be 1, 2, 3, 4, 5, 6 , 7, 8, 9, 10 There should be only a newline after the last number. Each number except the last should be followed by a comma and a space. To make your program more functional, you should parse command line arguments and change behavior based on their values. Argument Parameter Action -f, --first yes, an integer Change place you start counting -l, --last yes, an integer Change place you end counting -s, --skip optional, an integer, 1 if not specified Change the amount you add to the counter each iteration -h, --help none Print a help message including these instructions. -j, --joke none Tell a number based joke.
