Create a class named Invoicing that includes three overloaded computeInvoice() methods for a book store: see pages 196 for examples… The 8% tax should be defined as a constant.
1. When computeInvoice() receives a single parameter, it represents the price of one book ordered. Add 8% tax and display the total due.
2. When computeInvoice() receives two parameters, they represent the price of a book and the quantity ordered. Multiply the two values, add 8% tax, and display the total due.
3. When computeInvoice() receives three parameters, they represent the price of a book, the quantity ordered, and a coupon value. Multiply the quantity and price, reduce the result by the coupon value, and then add 8% tax and display the total due.
Create a driver class named TestInvoice with a main() method that tests all three overloaded methods using the following data: Price $24.95 Price, $17.50, quantity 4, Price $10.00, quantity 6, coupon $20.00 Output printed to Eclipse Console:
Price $26.95
Price $76.95
Price $43.20
Answer:
Follows are the method to this question:
class Invoicing //defining a class Invoicing
{
public static final double Tax = 8.0; //defining static variable Tax that holds a value
public static double Total;//defining a double variable Total
public void computeInvoice(double p1)//defining method computeInvoice that take double parameter
{
Total = p1 + p1 * (Tax / 100);//defining double variable Total that holds Price value
System.out.printf("Price $%.2f\n" , Total);//print calculated value
}
public void computeInvoice(double p2, int q)//defining method computeInvoice that takes integer and double parameter
{
Total = p2 * q;//use Total variable that calculate Price with Tax
Total = Total + (Total * (Tax/ 100));//calculate taxes on Total
System.out.printf("Price $%.2f\n" , Total);//print calculated value
}
public void computeInvoice(double p3, int q, double c)//defining method computeInvoice that takes one integer and two-double parameter
{
Total = p3 * q;//use Total to calculate Total price
Total = Total - c;//remove coupon amount from Total amount
Total = Total + (Total * (Tax/ 100));//calculate taxes on Total
System.out.printf("Price $%.2f\n" , Total);//print calculated value
}
}
public class TestInvoice //defining Main class TestInvoice
{
public static void main(String[] ar)//defining main method
{
Invoicing obm = new Invoicing ();//creating Invoicing class object obm
obm.computeInvoice(24.95);//calling method computeInvoice
obm.computeInvoice(17.5, 4);//calling method computeInvoice
obm.computeInvoice(10, 6, 20);//calling method computeInvoice
}
}
Output:
please find attached file.
Explanation:
In the above-given code, a class "Invoicing" is defined, inside the class two static double variable "Total and Tax" is defined, in which the Tax variable holds a value that is "8.0".
In class three same method, "computeInvoice" is used that accepts a different parameter for providing method overloading, which can be defined as follows:
In the first method, it accepts a single double parameter "p1", and inside the method, it uses the "Total" variable to calculate price value.In the second method, it accepts one integer and one double parameter "q and p2", and inside the method, it uses the "Total" variable is used to calculate the price with tax and print its value.In the third method, it accepts one integer and two double parameters "q, p3, and c", and inside the method, it uses the "Total" variable is used to calculate the price with tax and include tax and print its value.In the next step, the main class "TestInvoice" is defined inside the main method, Invoicing object is created and call its method.Create a TeeShirt class for Toby’s Tee Shirt Company. Fields include:
orderNumber - of type int size - of type String color - of type String price - of type double Create set methods for the order number, size, and color and get methods for all four fields. The price is determined by the size: $22.99 for XXL or XXXL, and $19.99 for all other sizes. Create a subclass named CustomTee that descends from TeeShirt and includes a field named slogan (of type String) to hold the slogan requested for the shirt, and include get and set methods for this field.
Answer:
Here is the TeeShirt class:
public class TeeShirt{ //class name
private int orderNumber; // private member variable of type int of class TeeShirt to store the order number
private String size; // to store the size of tshirt
private String color; // to store the color of shirt
private double price; // to store the price of shirt
public void setOrderNumber(int num){ //mutator method to set the order number
orderNumber = num; }
public void setColor(String color){ //mutator method to set the color
this.color = color; }
public void setSize(String sz){ //mutator method to set the shirt size
size = sz;
if(size.equals("XXXL") || size.equals("XXL")){ //if shirt size is XXL or XXXL
price = 22.99; // set the price to 22.99 if shirt size is XXL or XXXL
}else{ //for all other sizes of shirt
price = 19.99; } } //sets the price to 19.99 for other sizes
public int getOrderNumber(){ //accessor method to get the order number stored in orderNumber field
return orderNumber; } //returns the current orderNumber
public String getSize(){ //accessor method to get the size stored in size field
return size; } //returns the current size
public String getColor(){ //accessor method to get the color stored in color field
return color; } //returns the current color
public double getPrice(){ //accessor method to get the price stored in price field
return price; } } //returns the current price
Explanation:
Here is the sub class CustomTee:
public class CustomTee extends TeeShirt { //class CustomTee that inherits from class TeeShirt
private String slogan; //private member variable of type String of class CustomTee to store slogan
public void setSlogan(String slgn) { //mutator method to set the slogan

Consider a multiprocessor CPU scheduling policy. There are 2 options: 1) a singlecommon ready queue of jobs; when a CPU becomes free, the job atthe head of the queuegoes to this free CPU. 2) a ready queue for each CPU; the arriving job joins the shortestqueue. In general, do you expect the common queue or the shortest queue policy to performbetter. Justify.
Explanation:
A ready queue is more adequate since in this method the load balancing occurs in a proper way. The goal of multiple processing is the correct distribution of load.
But in the cases when a processor is doing quicker or taking a smaller queue, it will self assign processes allotted for execution, configuring it with a constant busy state.

How on earth do I fix my computer charger port?
Alright, so for anyone thinking it's a virus or it won't turn on, it's not that. So my computer has had a problem with batteries. I have bought two different chargers, none of those worked. I left the computer alone for a year, charged it for hope, and it worked. Upon further inspection, I looked at the charging port and found that the four metal things that go into the charger and pretty much give it the power were somewhat bent. Like, not bent bent, like when you fold paper, but all over the place. I tried watching videos to help, and they require buying a new motherboard or something like that. Is there a way to fix this for free? Like, a way to put the pings/pongs (idk the word) back together for free? If I can have someone give a step-by-step guide on how to fix this, I would appreciate it. I have had this problem since around 2017.

D. 4
Answer: C
Explanation: Computing Device A is connected using 3 wires, which all lead to multiple different paths of wires. If you break all the wires off of A, it leaves it with no paths to use. However, if you do this with E, there is 4 differents paths connected to it. Since you need the MINIMUM, the answer would be C.

Kara's teacher asked her to create a chart with horizontal bars. Which chart or graph should she use?
Bar graph
Column chart
Line graph
Pie chart
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is the Bar graph.
Because we use this chart type to visually compare values across a few categories when the charts show duration or when the category text is long.
However, we can present information similarly in the bar graph and in column charts, but if you want to create a chart with the horizontal bar then you must use the Bar graph. In an Excel sheet, you can easily draw a bar graph and can format the bar graph into a 2-d bar and 3-d bar chart.
A column chart is used to compare values across a few categories. You can present values in columns and into vertical bars.
A line graph chart is used to show trends over months, years, and decades, etc.
Pie Chart is used to show a proportion of a whole. You can use the Pie chart when the total of your numbers is 100%.

A Windows user is locked out of her computer, and you must log into the local administrator account HelpdeskAdmin. Which would you use in the username field?
Answer: .\HelpdeskAdmin
Explanation:
If you wanted to log in as the local administrator then for the Username put a dot (.) and a backslash (\) in front of the Admin username.
The dot(.) will ensure that Windows knows that you are logging into a local computer as the administrator and so will grant you access. The relevant username therefore is, ''.\HelpdeskAdmin''.
I will use .\HelpdeskAdmin as the username field.
What is a username field?The username-field is known to be a kind of command that is said to specifies the value for the name that shows the characteristics in the login form and it is one that identifies the username field.
Note that the use of the .\HelpdeskAdmin as the username field is the right thing to do as the dot(.) will make sure that the Windows knows that the user is logging into a computer as the administrator.

You've been hired by Maple Marvels to write a C++ console application that displays information about the number of leaves that fell in September, October, and November. Prompt for and get from the user three integer leaf counts, one for each month. If any value is less than zero, print an error message and do nothing else. The condition to test for negative values may be done with one compound condition. If all values are at least zero, calculate the total leaf drop, the average leaf drop per month, and the months with the highest and lowest drop counts. The conditions to test for high and low values may each be done with two compound conditions. Use formatted output manipulators (setw, left/right) to print the following rows:________.
September leaf drop
October leaf drop
November leaf drop
Total leaf drop
Average leaf drop per month
Month with highest leaf drop
Month with lowest leaf drop

maxDrop = max( num1, num2, num3);
minDrop = min(num1, num2, num3);
int n = sizeof(numbers)/sizeof(numbers[0]);
auto itr = find(number, number + n, maxDrop);
cout << "Highest drop: "<< month[ distance(numbers, itr) ] << endl = end;
auto itr1 = find(number, number + n, minDrop);
cout << "Lowest drop: " << month[ distance(numbers, itr1) ] << endl = end;
cout << "End of Maple Marvels";
Explanation:
The C++ source code above prompts for user input for three integer values of the leaf drop count through the September to November. The total drop, average, minimum and maximum leaf drop is calculated and printed out.
Suppose one machine, A, executes a program with an average CPI of 1.9. Suppose another machine, B (with the same instruction set and an enhanced compiler), executes the same program with 20% less instructions and with a CPI of 1.1 at 800MHz. In order for the two machines to have the same performance, what does the clock rate of the first machine need to be
Answer:
the clock rate of the first machine need to be 1.7 GHz
Explanation:
Given:
CPI of A = 1.9
CPI of B = 1.1
machine, B executes the same program with 20% less instructions and with a CPI of 1.1 at 800MHz
To find:
In order for the two machines to have the same performance, what does the clock rate of the first machine need to be
Solution:
CPU execution time = Instruction Count * Cycles per Instruction/ clock rate
CPU execution time = (IC * CPI) / clock rate
(IC * CPI) (A) / clock rate(A) = (IC * CPI)B / clock rate(B)
(IC * 1.9) (A) / clock rate(A) = (IC * (1.1 * (1.0 - 0.20)))(B) / 800 * 10⁶ (B)
Notice that 0.20 is basically from 20% less instructions
(IC * 1.9) / clock rate = (IC * (1.1 * (1.0 - 0.20))) / 800 * 10⁶
(IC * 1.9) / clock rate = (IC*(1.1 * ( 0.8))/800 * 10⁶
(IC * 1.9) / clock rate = (IC * 0.88) / 800 * 10⁶
clock rate (A) = (IC * 1.9) / (IC * 0.88) / 800 * 10⁶
clock rate (A) = (IC * 1.9) (800 * 10⁶) / (IC * 0.88)
clock rate (A) = 1.9(800)(1000000) / 0.88
clock rate (A) = (1.9)(800000000) / 0.88
clock rate (A) = 1520000000 / 0.88
clock rate (A) = 1727272727.272727
clock rate (A) = 1.7 GHz
