What is one advantage of using object-oriented programming?

A method countDigits(int num) of class Digits returns the remainder when the input argument num(num > 0) is divided by the nu

sertanlavr [38]

Answer:

#include <iostream>

using namespace std;

class Digits

{

public:

int num;

int read() //method to read num from user

{

cout<<"Enter number(>0)\n";

cin>>num;

return num;

}

int digit_count(int num) //method to count number of digits of num

{

int count=0;

while(num>0) //loop till num>0

{

num/=10;

count++; //counter which counts number of digits

}

return count;

}

int countDigits(int num) //method to return remainder

{

int c=digit_count(num); //calls method inside method

return num%c;

}

};

int main()

{

Digits d; //object of class Digits is created

int number=d.read(); //num is read from user

cout<<"\nRemainder is : "<<d.countDigits(number); //used to find remainder

return 0;

}

Output :

Enter number(>0)

343

Remainder is : 1

Explanation:

As program is missing to find errors , a logically write program is written to find the remainder when a number is divided by its number of digits. A class Digits is constructed which has public variable num and methods read(), digit_count(), countDigits().

read() - This method reads value of num from the user and return num.
digit_count() - This method takes a integer as parameter and counts the number of digits of a number passed as argument. while loop is used to increement the counter until num<0. This returns the value of count.
countDigits() - This method takes a integer as a parameter and returns remainder when the argument is divided by number of digits of argument. Number of digits is calculated by using method digit_count().

At last in main method , object of Digits class is created and its methods are used to find the output.

A group of statisticians at a local college has asked you to create a set of functions that compute the median and mode of a set

Vanyuwa [196]

Answer:

from functools import reduce

def mean(mylist):

score = reduce(lambda x,y: x + y, mylist)/ len(mylist)

return score

def median(mylist):

sorted(mylist)

list_len = len(mylist) % 2

i = round(len(mylist)/2)

x = len(mylist)//2

if list_len == 0:

median = (mylist[x] + mylist[x+1]) / 2

else:

median = mylist[i]

return median

def mode(mylist):

unique = set(mylist)

unique = list(unique)

collector = [mylist.count(key) for key in unique]

maxi = max(collector)

loc = collector.index(maxi)

return unique[loc]

def main():

scores = input( 'Enter list of numbers: ').split(",")

scores = [int(score) for score in scores]

operation = input('Enter operation: ')

operator = ['mean', 'median', 'mode']

for x in iter(list, 0):

if operation in operator:

break

print("Invalid operation: ")

operation = input('Enter operation')

index_loc = operator.index(operation)

if index_loc == 0:

return mean(scores)

elif index_loc == 1:

return median(scores)

#return np.median(scores) can be used of the defined function

elif index_loc == 2:

#return stats.mode(scores)[0] can be used of the defined function

return mode(scores)

print( main( ) )

Explanation:

The main python function calls conditionally three statistical functions namely mean, median and mode. It prompts for user input for a list of integer numbers and a function name name to return the corresponding result.

1 // Application contains a starting list of three products for sale2 // The user is prompted for additional items3 // After eac

madam [21]

Answer:

Here is the corrected code:

import java.util.*;

public class DebugNine36 { //class name

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

ArrayList<String>products = new ArrayList<String>(); //creates an ArrayList of type String names products

products.add("shampoo"); //add shampoo to product array list

products.add("moisturizer"); //add moisturizer product array list

products.add("conditioner"); //add conditioner product array list

Collections.sort(products); //sort the elements in products array list

display(products); //calls display method by passing products array list

final String QUIT = "quit"; //declares a variable to quit the program

String entry; //declares a variable to hold product/element or quit

Scanner input = new Scanner(System.in); //creates Scanner object

System.out.print("\nEnter a product or " + QUIT + " to quit >> "); //prompts user to enter a product or enter quit to exit

entry = input.nextLine(); //reads the entry value from user

while(!entry.equals("quit")) { //loops until user enters quit

products.add(entry); //adds entry (product) to products array list

Collections.sort(products); //sorts the elements in products array list

display(products); //calls display method by passing products arraylist

System.out.print("\nEnter a product or " + QUIT + " to quit >> "); //keeps prompting user to enter a product or enter quit to exit

entry = input.nextLine(); } } //reads the entry value from user

public static void display(ArrayList products) { // method to display the list of products

System.out.println("\nThe size of the list is " + products.size()); //displays the size of the array list named products

for(int x = 0; x < products.size(); ++x) //iterates through the arraylist products

System.out.println(products.get(x)); } } //displays each item/element in products array list

Explanation:

In the code the following statement are corrected:

1.

ArrayListproducts = new ArrayList();

This gave an error: cannot find symbol

This is corrected to :

ArrayList<String>products = new ArrayList<String>();

2.

products.add(shampoo);

products.add(moisturizer);

products.add(conditioner);

Here shampoo moisturizer and conditioner are String type items that are to be added to the products so these strings have to be enclosed in quotation marks.

This is corrected to :

products.add("shampoo");

products.add("moisturizer");

products.add("conditioner");

3.

display();

This method is called without giving any arguments to this method. The method display takes an ArrayList as argument so it should be passed the arraylist products to avoid error that actual and formal argument lists differ in length .

This is corrected to :

display(products);

The screenshot of output is attached.
