python A pet shop wants to give a discount to its clients if they buy one or more pets. The discount is equal to 20 percent of t

Artyom0805 [142]

Answer:

The following are the program in the Python Programming Language.

#define function

def discount(prices, isPet, nItems):

# declare and initialize variables to 0

i = 0

cost = 0

pets = 0

item = 0

item_Cost = 0

#set the while loop

while(i < nItems):

#check the items of the variable

if isPet[i]:

#add and initialize in the cost

cost += prices[i]

#increament in the variable by 1

pets += 1

#otherwise

else:

#add and initialize in the item_Cost

item_Cost += prices[i]

#increament in the variable by 1

item += 1

#then increment in the variable by 1

i += 1

#check the pet is greater than equal to 1

#and item is greater than equal to 5

if(pets >= 1 and item >=5):

#then, print the message

print("You receive discount")

#set discount of the items

discount = 0.2 * item_Cost

# calculate bill after deducting discount

bill = cost + item_Cost - discount

#print the bill

print("Final Bill amount is", bill)

#otherwise

else:

#print the message

print("You do not receive any discount")

#calculate bill without deducting discount

bill = cost + item_Cost

#print the final bill

print("Final Bill amount is", bill)

#set empty list type variables

price = []

pet = []

#set the infinite loop

while True:

#get input from the user

sprice = int(input("Enter the price (-1 to quit): "))

#check that price is not equal to the -1

if(sprice != -1):

#add price in the list

price.append(sprice)

#ask for choice from the user

choice = input("Is it a pet (Y / N)? ")

#check the choice of the user is y or Y

if(choice == 'Y' or choice == 'y'):

# then, add in the pet

pet.append(True)

#otherwise

else:

#not add in the pet

pet.append(False)

print("")

#break the loop

else:

break

#declare variable that store the length

items = len(price)

#call and initialize the variable

discount(price, pet, items)

<u>Output</u>:

Enter the price (-1 to quit): 96

Is it a pet (Y / N)? y

Enter the price (-1 to quit): 69

Is it a pet (Y / N)? n

Enter the price (-1 to quit): 41

Is it a pet (Y / N)? n

Enter the price (-1 to quit): 52

Is it a pet (Y / N)? n

Enter the price (-1 to quit): 96

Is it a pet (Y / N)? n

Enter the price (-1 to quit): 74

Is it a pet (Y / N)? n

Enter the price (-1 to quit): -1

You receive discount

Final Bill amount is 361.6

Explanation:

<u>The following are the description of the program</u>.

Firstly, define the function 'discount()' and pass the arguments 'prices', 'isPet' and 'nItems' in its parameter.
Then, declare and initialize the variables 'i' to 0, 'item_Cost' to 0
, item to 0, 'cost' to 0 and 'pets' to 0.
Then, set the while loop to add the price of the items and the cost of the pets.
Set the if-else conditional statement to check the pet is greater than equal to 1 and the items are greater than equal to 5 then, set the discount and print the bill after deduction.
Otherwise, print the bill without deduction.
Finally, set two list type variable then, set the infinite while loop that gets input from the user and check that the variable is not equal to -1 then append the data in the list then again check the user input then append in pet otherwise not append in pet and break the loop. Then, set the variable that stores the length of the price and call the following function by passing arguments in its parameter.

Briefly explain the following terms and concepts:

morpeh [17]

Answer:

Answer below

Explanation:

Maximum transmission unit (MTU)

A maximum transmission unit (MTU) is the largest packet or frame size that is usually specified in Eight-bit bytes, which can be sent in a packet or frame-based network such as the internet.

Longest Prefix Match

Longest prefix match is an algorithm used by routers in Internet Protocol to lookup the IP prefix that will likely be the terminal point of the next hop from the router.

CIDR and Subnet Mask

CIDR, known in full as Classless inter-domain routing, is a set of IP standards that is used to make customized identifiers for networks and individual devices.

A subnet mask separates the internet protocol (IP) address into the network address and host address.

Switching Fabric

Switching fabric is simply an arrangement of the elements of a communication network also known as network topology, whereby the nodes of the network are seen to interconnect with one or more network switches.

Write an application that determines which, if any, of the following files are stored in the folder where you have saved the exe

Elza [17]

Answer:

Here is the JAVA application that determines which if any of the following files are stored in folder where you have saved the exercises created.

import java.nio.file.*; // used to manipulate files and directories

import java.nio.file.attribute.*; //used to provide access to file and file attributes

import static java.nio.file.AccessMode.*; // provides access modes to test the accessibility of a file

import java.io.IOException; //for exception handling

class FindSelectedFiles {

public static void main(String[] args) { //start of main function

Path f1 = Paths.get("/root/sandbox/autoexec.bat"); //creates Path object f1 using Paths.get() method and this instance contains the file name and directory list used to construct the specified path

Path f2 = Paths.get("/root/sandbox/CompareFolders.java"); //creates Path object f2 using Paths.get() method and this instance contains the file name and directory list used to construct the specified path

Path f3 = Paths.get("/root/sandbox/FileStatistics.class"); //creates Path object f3 using Paths.get() method and this instance contains the file name and directory list used to construct the specified path

Path f4 = Paths.get("/root/sandbox/Hello.doc"); //creates Path object f4 using Paths.get() method and this instance contains the file name and directory list used to construct the specified path

int count=0; //used to count the number of files found

try{ // used to define a code chunk to be tested for errors

f1 = Paths.get("/root/sandbox/autoexec.bat"); // Converts a path string when joined form a path string to a Path

System.out.println(f1); //prints the file

/* getFileSystem method is used to return the file system that created this Path object f1 and checkAccess Verifies access and throws exception if something is wrong

f1.getFileSystem().provider().checkAccess(f1);

System.out.println(f1 +" File Exists\n"); //if file exists then displays this message

count++; } //adds 1 to the count of number of files found

catch (IOException e) { //a code chunk to be executed if error occurs in the try part

System.out.println("File Doesn't Exist\n"); } //if file not found displays this message

try{ //works same as above try block but for 2nd folder and object f2

f2 = Paths.get("/root/sandbox/CompareFolders.java");

System.out.println(f2);

f2.getFileSystem().provider().checkAccess(f2);

System.out.println(f2 +" File Exists\n");

count++; }

catch (IOException e) {

System.out.println("File Doesn't Exist\n"); }

try{ //works same as above try block but for 3rd folder and object f3

f3 = Paths.get("/root/sandbox/FileStatistics.class");

System.out.println(f3);

f3.getFileSystem().provider().checkAccess(f3);

System.out.println("File Exists\n");

count++; }

catch (IOException e) {

System.out.println("File Doesn't Exist\n"); }

try{ //works same as above try block but for 4th folder and object f4

f4 = Paths.get("/root/sandbox/Hello.doc");

System.out.println(f4);

f4.getFileSystem().provider().checkAccess(f4);

System.out.println(f4 +" File Exists\n");

count++; }

catch (IOException e) {

System.out.println("File Doesn't Exist\n"); }

System.out.println(count+" of the files exist"); } } //displays the number of files found

Explanation:

If you want to directly pass the file name as argument to Paths.get() method then you can use the following code:

Path f1 = Paths.get("autoexec.bat");

Path f2 = Paths.get("CompareFolders.java");

Path f3 = Paths.get("FileStatistics.class");

Path f4 = Paths.get("Hello.doc");

The program determines if any, of the files from autoexec.bat, CompareFolders.java, FileStatistics.class, and Hello.doc. are stored in the folder. If a file is found then the program displays the message File exists and add 1 to the count variable each time a file is found. If all the files are found then the program returns the count as 4 otherwise the program display the number of files found by displaying the computed final value of count in the output. Lets say all the files are found then the output of the above program is:

autoexec.bat autoexec.bat File Exists

CompareFolders.java CompareFolders.java File Exists

FileStatistics.class File Exists

Hello.doc Hello.doc File Exists

4 of the files exist
