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
}
}

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.

Given the dictionary, d, find the largest key in the dictionary and associate the corresponding value with the variable val_of_max. For example, given the dictionary {5:3, 4:1, 12:2}, 2 would be associated with val_of_max. Assume d is not empty.
Answers
Answer:
Here is the Python program:
d = {5:3, 4:1, 12:2}
val_of_max = d[max(d.keys())]
print(val_of_max)
Explanation:
The program works as follows:
So we have a dictionary named d which is not empty and has the following key-value pairs:
5:3
4:1
12:2
where 5 , 4 and 12 are the keys and 3, 1 and 2 are the values
As we can see that the largest key is 12. So in order to find the largest key we use max() method which returns the largest key in the dictionary and we also use keys() which returns a view object i.e. the key of dictionary. So
max(d.keys()) as a whole gives 12
Next d[max(d.keys())] returns the corresponding value of this largest key. The corresponding value is 2 so this entire statement gives 2.
val_of_max = d[max(d.keys())] Thus this complete statement gives 2 and assigns to the val_of_max variable.
Next print(val_of_max) displays 2 on the output screen.
The screenshot of program along with its output is attached.
According to Darwin’s theory of evolution, differences between species may be a result of which of the following?
a) The disuse of body structures
b) The transmission of acquired characteristics
c) Natural selection
d) Mutagenic agents
Answers
Answer:
The answer is C Natural selection
Explanation:
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations
According to Darwin’s theory of evolution, differences between species may be a result of Natural selection. Thus the correct option is C.
What is Darwin’s theory of evolution?According to Darwin, all species descended from a single ancestor, species can change through time, and new species can arise from existing ones which makes them interconnected with common traits.
Natural selection of traits in a species that would help the species in its survival is the process that drives diversification, the evolutionary process through which new biological species form.
Natural selection is the evolutionary mechanism stating that with many resources available in nature, creatures with genetically inherited features that promote survival and reproduction will typically produce more offspring than their conspecific competitors.
Therefore, option C is appropriate.

Which of the following is true of how packets are sent through the internet?
Answers
Answer:
It is A: Packet metadata is used to route and reassemble information travelling through the internet.
Explanation:
Step 1: The Internet works by chopping data into chunks called packets. Each packet then moves through the network in a series of hops. Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee
Step 2: Entering the network
Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee.
Step 3: Taking flight
The next hop delivers the packet to a long-haul provider, one of the airlines of cyberspace that quickly carrying data across the world.
Step 4: BGP
These providers use the Border Gateway Protocol to find a route across the many individual networks that together form the Internet.
Step 5: Finding a route
This journey often takes several more hops, which are plotted out one by one as the data packet moves across the Internet.
Step 6: Bad information
For the system to work properly, the BGP information shared among routers cannot contain lies or errors that might cause a packet to go off track – or get lost altogether.
Last step: Arrival
The final hop takes a packet to the recipient, which reassembles all of the packets into a coherent message. A separate message goes back through the network confirming successful delivery.

The purpose of performance profiling (experimental analysis) is to measure the program/algorithm performance. Assume that you have performed an experimental analysis of an algorithm, and profiling returned the following
times: for instances of sizes 2^10, 2^11, 2^12, 2^13, 2^14
the corresponding times are approximately 300 , 510 , 905 , 1750 , 3305 milliseconds.
In these collected running times, there is an extra overhead resulting from clocking program performance and OS functions calls, and this overhead has to be considered in analyzing data. That is, the measured time consists of two components: the time for executing the operations, plus the overhead from profiling.
The estimated overhead due to profiling is about 100 milliseconds independently of the input size. (that is, 100 is always an additive ``constant'' in the collected times).
Based on these experimental results, what is the running time, as a function of the problem size, for executing this algorithm? (c is a constant).
A. O(underroot(n)).
B. O(n^2).
C. O(n).
D. None of the listed.
E. O(n log n).
Answers
Answer:
C. O(n).
Explanation:
for better understanding, the os is a program that helps in telling how much resources can be used and when processor can be accessed.
to each programme data structures would load and unload every time that a programme is to be run.
while a programme is being managed there would be extra overheads and based on whatever type of os or programme that this is, it may or may not have fixed overhead
from our question overhead is fixed at 100ms
we have,
net time as: 300-100, 510-100, 905-100, 1750-100, 3305-100,
which is, 200, 410, 805, 1650, 3205
when we double 2¹⁰ to 2¹¹ to 2¹² etc, the programme ran is also doubling
this says that run time is same as size of instance n

Memory locations in personal computers are usually given in hexadecimal. If a computer programmer writes a program that requires 100 memory locations, determine the last memory location that is used if the program starts at location 2C8DH 16 hexadecimal
Answers
Answer:
The answer is "The last memory addresses used by a specific program is 2CF0".
Explanation:
For this specific problem, we assume that only a memory storage allocation like Array data structure is needed, as well as any allocation only needs one memory cell since it focuses on the structure and type of data used.
So, first, we will transform the provided memory address for better comprehension from Hexadecimal into decimal.
[tex]\to \bold{(2C8D)_{16} = (11405)_{10}}[/tex]
Now 11405 is the first memory cell's address. With all of this number, it can add 99, resulting in the final decimal memory address.
[tex]=11405 + 99\\\\= 11504[/tex]
[tex]\bold{(11504)_{10} = (2CF0)_{16}}.[/tex]

Write a program named as calcPrice.c that formats product information entered by the user and calculate the total amount of purchase.
Answers
Answer:
Here is the calcPrice.c program:
#include <stdio.h> //to use input output functions
int main(void) { //start of main method
int itemNo, month, day, year, quantity; //declares variables to hold item number, quantity, and date
float unitPrice; //declare variable to hold price per unit
printf("Enter item number: "); // prompts user to enter item number
scanf("%d", &itemNo); //reads item number from user and stores it in itemNo variable
printf("Enter unit price: "); // prompts user to enter unit price
scanf("%f", &unitPrice); //reads input unit price and stores it in unitPrice variable
printf("Enter quantity: "); //prompts user to enter quantity
scanf("%d", &quantity); //reads input quantity and stores it in quantity variable
printf("Enter purchase date (mm/dd/yyyy): "); //prompts user to enter purchase date
scanf("%d/%d/%d", &month, &day, &year); //reads input date and stores it in month, day and year variables
float totalAmount = unitPrice * quantity; //computes the total amount
printf("\nItem\tUnit Price\tQTY\tPurchase Date\tTotal Amount\n"); //displays the item, unit price, qty, purchase data and total amount with tab space between each
printf("%d\t$%5.2f\t%d\t%.2d/%.2d/%d\t$%5.2f\n", itemNo, unitPrice,quantity, month, day, year,totalAmount); } //displays the values of itemNo, unitPrice, quantity, month, day, year and computed totalAmount with tab space between each
Explanation:
Lets suppose user enters 583 as item number, 13.5 as unit price, 2 as quantity and 09/15/2016 as date so
itemNo = 583
unitPrice = 13.5
quantity = 2
month = 09
day = 15
year = 2016
totalAmount is computed as:
totalAmount = unitPrice * quantity;
totalAmount = 13.5* 2
totalAmount = 27.00
Hence the output of the entire program is:
Item Unit Price QTY Purchase Date Total Amount
583 $ 13.50 2 09/15/2016 $ 27.00
The screenshot of the program along with its output is attached.

This is the right code;
x = 1
while(x < 26):

Explanation:
The Beaufort Wind Scale is used to characterize the strength of winds. The scale uses integer values and goes from a force of 0, which is no wind, up to 12, which is a hurricane. The following script first generates a random force value. Then, it prints a message regarding what type of wind that force represents, using a switch statement. If random number generated is 0, then print "there is no wind", if 1 to 6 then print "this is a breeze", if 7 to 9 "this is a gale", if 10 to 11 print "this is a storm", if 12 print "this is a hurricane!". (Hint: use range or multiple values in case statements like case {1,2,3,4,5,6})
Required:
Re-write this switch statement as one nested if-else statement that accomplishes exactly the same thing. You may use else and/or elseif clauses.
ranforce = randi([0, 12]);
switch ranforce
case 0
disp('There is no wind')
case {1,2,3,4,5,6}
disp('There is a breeze')
case {7,8,9}
disp('This is a gale')
case {10,11}
disp('It is a storm')
case 12
disp('Hello, Hurricane!')
end
Answers
Answer:
The equivalent if statements is:
ranforce = randi([0, 12]);
if (ranforce == 0)
disp('There is no wind')
else if(ranforce>0 && ranforce <7)
disp('There is a breeze')
else if(ranforce>6 && ranforce <10)
disp('This is a gale')
else if(ranforce>9 && ranforce <12)
disp('It is a storm')
else if(ranforce==12)
disp('Hello, Hurricane!')
end
Explanation:
The solution is straight forward.
All you need to do is to replace the case statements with corresponding if or else if statements as shown in the answer section
