Chapter 2, Problem 5E
Create an application that calculates and displays two raise amounts, which are based on an employee’s current salary. The current salary will be entered by the user. The two raise rates are 5% and 8%. In addition to the raise amounts, the application should also calculate and display the employee’s new salaries. Include a button in the interface that the user can click to clear the user input and calculated results from the screen.
- a. Prepare a Planning Chart for the application.
- b. Draw a sketch of an appropriate interface. Be sure to follow the GUI design guidelines covered in the chapter. The guidelines are summarized in Figure 2-20. (If you want to include an image in the interface, you can either use your own image file or download an image file from openclipart.org. When downloading from openclipart.org, be sure to use the SMALL IMAGE (.PNG) button.)
- c. Create a Windows Forms application. Use the following names for the project and solution, respectively: Salary Project and Salary Solution. Save the application in the VB2017\Chap02 folder.
- d. Use your Planning Chart as a guide when building the interface.
- e. Code the Exit button. (You do not need to code the button that calculates and displays the raises and new salaries or the button that clears the user input and calculated results.)
- f. Save the solution and then start the application. Test the access keys, tab order, and Exit button and then close the solution.

1.[30 pts] Computers generate color pictures on a video screen or liquid crystal display by
mixing three different colors of light: red, green, and blue. Imagine a simple scheme, with
three different lights, each of which can be turned on or off, projecting onto a glass screen:
We can create eight different colors based on the absence (0) or presence (1) of light
sources R,G and B:

Each of these colors can be represented as a bit vector of length 3, and we can apply
Boolean operations to them.
a. The complement of a color is formed by turning off the lights that are on and turning
on the lights that are off. What would be the complement of each of the eight colors
listed above?
b. Describe the effect of applying Boolean operations on the following colors:
Λ
1. Red(100) ^ Magenta(101)= Blue(001)
2. Bue(001) | Green(010)=
3. Yellow(100) & Cyan(011)=

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;
