Question
Chapter 2.2, Problem 10STE
Program Plan Intro
Outputting values of type “double”:
- Using the below statement user can formatting the number with a decimal point when a number of type “double”.
cout.setf(ios::fixed);
cout.setf(ios::showpoint);
cout.precision(4);
- The above three statement must include for formatting a decimal point but the last line “cout.precision(4)” defines the how many digits needs after the decimal point.

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;
