Cryptocurrencies are digital tokens that are created independently of government money, and can act as a medium of exchange and store of value. Which other instrument could most reasonably fulfill the same function

Answers

Answer 1

Answer:

Gold

Explanation:

From the question, we are informed about Cryptocurrencies which are digital tokens that are created independently of government money, and can act as a medium of exchange and store of value. One of other instrument that could most reasonably fulfill the same function is Gold. A medium of exchange can be regarded as a intermediary instrument which is a function of money that facilitate trade or purchase and selling between seller and buyers, and it must be accepted as payment for transactions. Such intermediary instrument as a medium of exchange are Gold, salt as well as stone. Gold was chosen by most of the commodity-money advocates as a medium of exchange as a result of the intrinsic property it posses, and it's fixed stock value

Write a C++ program to define an abstract class in polymorphism?

Answers

Answer:

Following are the program to this question:

#include <iostream>//header file

using namespace std;//namespace

class Val //defining abstract class

{

  public://use access specifier

     virtual int squ()=0;//declaring a method squ  

     void setval(int x) //defining a method setval

     {

        a=x;//holding value in a variable

     }

  protected://use access specifier

     int a;//defining integer variable

};

class square: public Val //defining a class square that inherit abstract class

{

  public://use access specifier

   int squ() //defining squ method

   {  

   return (a*a); //return square value

   }

};

int main() //main method

{

 square s;//creating class object

 s.setval(5);//calling setval method

 cout << "The square value is: " << s.squ() << endl;//print value by calling squ method

}

Output:

The square value is: 25

Explanation:

In the above code a two-class "Val and square" is declared, in which val is abstract class, in a method squ is declared, and setval is used to set the value.

In the next step, the square class inherits Val and defines the squ method, and uses the return keyword to return its calculated value.

In the main method square class object is created and set the setval value and call the squ method and print its value.

How would you create a 2D array of Strings called paintSwatches that holds the paint manufacturer, paint color name and the paint collection name (in that order) for each of the 60,000 paint swatches a store carries

Answers

Answer:

String[][] paintSwatches = new String[6000][3];

Explanation:

The two-dimensional array is a data structure that holds and locates data in rows and columns. It is denoted by two square brackets after the data type when declaring the array.

The two-dimensional array "paintSwatches" would have 6000 rows and one column each of paint manufacturer, paint color name and paint collection name (that is, 3 columns).

Write a program that reads 20 integers from the user into an array and uses a function arrayMinimum that accepts an integer array along with its size as parameters and returns the smallest element of the array. The program needs to output the result (the smallest array element).

Answers

Answer:

#include <iostream>

using namespace std;

int arrayMinimum(int myArray[], int myArraySize) {

int small = myArray[0];

for (int i = 0; i < myArraySize; i++) {

   if(myArray[i]<small){

small = myArray[i];

}

 }

 return small;

}

int main(){

   int myArray[20];

   for(int i =0;i<20;i++){

       cin>>myArray[i];          

   }

   cout<<"The smallest is: "<<arrayMinimum (myArray,20);

   return 0;

}

Explanation:

This solution is provided in c++

#include <iostream>

using namespace std;

This line defines the arrayMinimum function

int arrayMinimum(int myArray[], int myArraySize) {

This initializes the smallest of the array element to the first

int small = myArray[0];

This iterates through the array

for (int i = 0; i < myArraySize; i++) {

This if condition checks for the smallest

   if(myArray[i]<small){

The smallest is assigned to the small variable

small = myArray[i];

}

 }

This returns the smallest

 return small;

}

The main method begins here

int main(){

This declares an array of 20 elements

   int myArray[20];

The following iteration allows user input into the array

   for(int i =0;i<20;i++){

       cin>>myArray[i];          

   }

This calls the method and returns the minimum

   cout<<"The smallest is: "<<arrayMinimum (myArray,20);

   return 0;

}

Answers

Answer:

b) public static double calcShippingCost(double weight) { double cost; if(weight < 10) { cost = 10.0; }else{ cost = 15.5; } cost = cost + calcTax(cost); return cost; }

The method is called twice with arguments 7.5 and 17.5 respectively.

Explanation:

The Java program defines three user methods including the main. In the main, the calShippingCost method is called twice with 7.5 and 17.5 respectively to return double number values to cost1 and cost2.

Write a class called Dragon. A Dragon should have a name, a level, and a boolean variable, canBreatheFire, indicating whether or not the dragon can breathe fire. The class should have getter methods for all of these variables- getName, getLevel, and isFireBreather, respectively. Dragon will alsomeed a constructor, a method to gain experience, and a method to attack. The constructor should take the name as the first argument and the level as the second argument. The constructor should initialize canBreatheFire based on the dragon's level. If the dragon is level 70 or higher, the dragon can breathe fire (meaning the third member variable should be set to true). You should create three getter (accessor) methods called getNameO getLevelO,and isFireBreatherO You should also create a method called attackO. This method does not return anything. If the dragon can breathe fire, it should print >>>999 1 public class Dragon private String name; private int level; private boolean canBreatheFire; 4 7 // Write the constructor here! public String getName(name) 9 10 return name; 12 13 14 - 15 public int getLevel(level) return level; 16 17 /Put getters here 18 19 20 21 221/ String representation of the object 23 24 - 25 26 27 3 28 // Put other methods here public String toStringO return "Dragon+ name +" is at level "+ level; 1 public class DragonTester extends ConsoleProgram 2 4 6 public void runCO // Start here! 7

Answers

Answer:

public class Dragon {

private String name;

private int level;

private boolean canBreatheFire;

public Dragon(String name,int level){

this.name=name;

this.level=level;

if(level>=70) {

this.canBreatheFire=true;

}

}

public String getName() {

return name;

}

public int getLevel() {

return level;

}

public boolean getCanBreatheFire() {

return canBreatheFire;

}

public void attack() {

if(getCanBreatheFire()) {

System.out.println(">>> 999");

}else {

System.out.println("Dragon does not have fire breath.");

}

}

public void gainExperience() {

level += 5;

}

public String toString() {

return "Dragon "+ name + " is at level "+ level;

}

Explanation:

The Java program above is a class called Dragon. An object instance of the dragon class has a name and level class variable. The level is used to determine the Boolean value of the canBreathFire class variable. The variables can be retrieved with the getter methods and the level updates by the experience method.

You are reviewing the output of the show interfaces command for the Gi0/1 interface on a switch. You notice a significant number of CRC errors displayed. What are the most likely causes

Answers

Answer:

Collision or electromagnetic interference (EMI)

Explanation:

Some network cables connected to switch or router ports are prone to internal collision (between two frames or packets) and external collision with electromagnetic waves from other sources (EMI).

Electromagnetic waves are also known as radio waves or signals. When they are transmitted, the network cable acts as a receiver, the received signal interferes with the packet in the cable. This is why the cyclic redundancy check (CRC) throws an error.

What are the correct steps to add the bill using the receipt capture feature in quick books online?

Answers

Answer:

How it Works

The Bill can be imported into QuickBooks in a verity of methods such as drag and drop, browse to upload, email and image upload from a mobile device. The imported data is processed by QuickBooks. In my testing this processing varied depending on the type of document sent but overall, the process was fast, and the Bill was ready to view and categorized within five minutes. There were several pieces of data already extracted from the document which were the data and dollar amount but all other details in my experience needed to be entered.

One thing to not is you can not expense by line items at this time. Instead you can only choose one expenses account per transaction. (if I were a betting girl, I would say this is in the works, but I have no official word on that) However, you can add Classes and Billable Customers.

How to Get Started:

1) From the QBO Navigation Bar choose Banking Center

2) Select the Receipts tab

3) Drag and drop, email or upload a mobile image of the document to QuickBooks (1 file at a time)

4) From the For Review section of the Receipts tab you can see when the document is ready for review

5) QuickBooks extracts, data including date and dollar amount

6) Click on Review in the Action column

7) Select Bill as Document Type (as shown highlighted in the 'red box')

8) Enter the remaining details:

- Enter Payee

- Approve Bill date and enter due date

- Select Account  

- Verify amount total

- Additional Fields (optional)

- Make expenses billable

- Select Customer

- Class

- Add reference number

9) Import into QuickBooks by Saving and Closing

Within, seconds your document is coded and published into QuickBooks as an Open Bill pending payment. Like I said for now all you can add is an account but if you published the document to QBO you could later open it and edit to add required items if necessary.

The last step in optimization is after you have posted the payment to the open bill you will be able to match the bank feeds in QBO if you have already imported your banking activity. This type of audit proofing your bookkeeping helps prevent fraud and assures accuracy.

Hope this helps!! Merry Christmas!! And Happy New Year!!

PYTHONSorting TV Shows (dictionaries and lists)Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons).Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt, separating multiple TV shows associated with the same key with a semicolon (;). Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt.Ex: If the input is:file1.txtand the contents of file1.txt are:20Gunsmoke30The Simpsons10Will & Grace14Dallas20Law & Order12Murder, She Wrotethe file output_keys.txt should contain:10: Will & Grace12: Murder, She Wrote14: Dallas20: Gunsmoke; Law & Order30: The Simpsonsand the file output_titles.txt should contain:DallasGunsmokeLaw & OrderMurder, She WroteThe SimpsonsWill & Grace

dict_keys = sorted(mydict.keys)

sorted_dict ={}

writn.write("\n")

dict_values = sorted(mydict.values)

with open("output_titles", "a+") as title:

for name in dict_values:

title.write(name)

title.write("\n")

Explanation:

The python program above reads in the file context, files.txt, and creates a dictionary of the file with the number of seasons as the key and movie title as the value. The sorted dictionary is saved in the output_keys.txt file and the titles in output_titles.txt file.

Let us consider the easiest sorting algorithms – Maxsort. It works as follows: Find the largest key, say max, in the unsorted section of array (initially the whole array) and then interchange max with the element in the last position in the unsorted section. Now max is considered part of the sorted section consisting of larger keys at the end of the array. It is no longer in the unsorted section. Repeat this until the whole array is sorted. a) Write an algorithm for Maxsort assuming an array E contains n elements to be sorted, with indexes 0, 1,…,n-1. b) How many comparisons of keys does Maxsort do in the worst case and on average? Submit source code, test cases, results, and the answers to part (b)

Answers

Answer:

count = 0

for x in range(len(array)):

if count == Len(array) -1:

break

max = max(array[:-1 - count])

count += 1

if array.index(max) == -1:

break

else:

hold = array[-1]

array[-1] = max

array[array.index(max)] = hold

Explanation:

The python program is an implementation of a maxsort. The for loop iterates over the array, getting the maximum number for each reduced array and swaps it with the corresponding last items.
