Question
Chapter 3, Problem 66E
Program Plan Intro
RGB:
Three primary colors in RGB color model are Red, Green, and Blue. The combination of these three primary colors can be used to produce 16.5 million colors.
- Computers are designed to use RGB output device which uses RGB values.
- Three numbers are used for every color in RGB mode to indicate the contribution of three primary colors for its color formation.
- Each color in RGB is represented using 8 bits and it ranges from 0 to 255.
- The color’s numeric value “0” indicates that no contribution has been provided by that color to form a new color.
- The color’s numeric value “255” indicates the full contribution has of that color to form a new color.

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 {

- 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.
