Chapter 2, Problem 23PS
Explanation of Solution
Appearance of scripting languages more frequently than new compiled languages:
Scripting languages are those languages which supports writing scripts. Scripts are programs written for automating execution of some tasks which could be completed step by step by human operator.
Scripting languages are more compared to compiling languages in modern times due to their advantages over compiling languages. The main advantages are as follows:
- It is easier to write the code in a scripting language than in a compiled language.
- Scripting languages have high- level statements than complied language.
- So, it is easy to complete tasks for which scripts were designed.
- Moreover, scripting languages are more powerful.
- Example Perl has lot of tools for easy manipulation of text files
- A compiled language requires a write, compile, deploy and run cycle...

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) {

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.
