What two features distinguished Windows 2.0 from Windows 1.0?
zysi [14]
This question is a bit ambiguous as there were a few features that were added and any could be perceived as distinguishing depending on what you look for in your OS. I do believe this is in reference to the Wikipedia article on Windows 2.0 though as the first two listed features make note of Windows 1.0 specifically, therefore:

Windows 2.0 allowed windows to overlap, Windows 1.0 could not do this.

Windows 2.0 introduced new and more complex keyboard shortcuts and terminology such as "Minimize" and "Maximize" vs. Window 1.0's "Iconize" and "Zoom"

Following are the python program to the given question:

from collections import defaultdict #import package

import heapq as h#import package

def primsMST(gr, st_v): # defining a method primsMST that takes two values in parameters  

   primalMST = defaultdict(set)#defining primalMST as a variable that calls defaultdict method  

   v = set([st_v])# defining a variable v that calls the set method and hold its value

   e_list = [(c, st_v, to)for to, c in gr[st_v].items()]#defining variable e_list that use loop to hold value in list

   h.heapify(e_list)# use package that holds heapify and holds its value

   while e_list:#defining while loop that checks e_list  

       c, s, e = h.heappop(e_list)#holding heapop method value in c,s,and e variable

       if e not in v:#defining if block checks e value is not in v

           v.add(e)# use add method to add value in v

           primalMST[s].add(e)#use primalMST as list that adds value in mwthod

   for nxt, c in gr[e].items():#defining for loop that uses nxt, and c variable that checks value in list

       if nxt not in v:#defining nxt variable that checks value is not in v

           h.heappush(e_list, (c, e, nxt))#add value into the heappush method

   return primalMST#return method value

connects=[['A','B',1],['B','C',4],['B','D',6],['D','E',5],['C','E',1]]#defining a list connects

my_gr=dict()#defining a variable my_gr that holds method dict() value  

for el in connects:#defining a for loop that uses el to count connects list value

   my_gr[el[0]]=dict()#use my_gr as list hold value in dict method

   my_gr[el[1]]=dict()#use my_gr as list hold value in dict method

for el in connects:#defining another for loop that uses el to count connects list

   my_gr[el[0]].update({el[1]:el[2]}) # use update method that update value in my_gr

   my_gr[el[1]].update({el[0]:el[2]})# use update method that update value in my_gr

x=dict(primsMST(my_gr, list(my_gr.keys())[0]))#defining x variable that calls dict method and  hold its value  

a=[]#defining an empty list

for k in x:#defining a for loop that uses k to hold dict method value

   for no in x[k]:#defining a loop that checks list value

       a.append([k,no,my_gr[k][no]])#use a that add value in list  

       print(a)#print list value.

Output:

Please find the attached file.

Program Explanation:

  • Import package.
  • defining a method primsMST that takes "gr and st_v" as parameters.
  • Inside the method, a primalMST as a variable is declared that calls "defaultdict" method.
  • Use the v variable that calls the set method and hold its value.
  • Defining "e_list" that uses the loop to hold value in lists, and define the heapify and holds its value.
  • In the next step, it defines a while loop checks e_list, and defines variable and hold value into the method and use another if to check value and return its value.
  • A list "connects" is declared that holds a value and defines a "my_gr" that holds "dict" method value and uses multiple for loop to print the calculated list value.

Write a program that calculates the future value of an investment at a given interest rate for a specified number of years. The
baherus [9]
<h2>Question:</h2>

Write a program that calculates the future value of an investment at a given interest rate for a specified number of years. The formula for the calculation is as follows:

futureValue = investmentAmount * (1 + monthlyInterestRate) ^ years * 12

Note: Allow users to enter the values of the investmentAmount, monthlyInterestRate and years from standard input.

Assume the number of years is always a whole number.

<h2>Answer:</h2>

===================================================

//import the Scanner class

import java.util.Scanner;

//Class header definition

public class FutureValue{

   

    //Main method definition

    public static void main(String []args){

       

       //Create an object of the Scanner class

       Scanner input = new Scanner(System.in);

       

       //Prompt the user to enter the investment amount

       System.out.println("Enter the investment amount");

       

       //Store the input in a double variable called investmentAmount

       double investmentAmount = input.nextDouble();

       

       //Next, prompt the user to enter the interest rate

       System.out.println("Enter the interest rate in percentage");

       

       //Store the input in a double variable called interestRate

       double interestRate = input.nextDouble();

       

       //Convert the interest rate to decimal by multiplying by 0.01

       interestRate *= 0.01;

       

       //Convert the interest rate to monthly interest rate by dividing the

       //result above by 12

       double monthlyInterestRate = interestRate / 12;

       

       //Prompt the user to enter the number of years

       System.out.println("Enter the number of years");

       

       //Store the input in an integer variable called years

       int years = input.nextInt();

       

       //Using the given formula, find the future value

      double futureValue =  investmentAmount * Math.pow(1 + monthlyInterestRate, years * 12);

       

       //Print out the future value

      System.out.println("Future value : " + futureValue);

       

    } //End of main method

     

}  // End of class definition

===================================================

<h2>Sample Output</h2>

===================================================

<em>>> Enter the investment amount </em>

1000

>> <em>Enter the interest rate in percentage </em>

10

>> <em>Enter the number of years </em>

5

Future value : 1645.3089347785854

===================================================

<h2>Explanation:</h2>

The code above has been written using Java. The code contains comments explaining every line of the code. Please go through the comments. The actual lines of code have been written in bold-face to distinguish them from comments. A sample output has also been provided as a result of a run of the code.

Please help with this coding problem! Any help is greatly appreciated!!
Nonamiya [84]

The python program is an illustration of python functions; Functions are names statements that are executed when called.

<h3>The order in which the statements are executed?</h3>

The program uses functions, and the functions would be executed when called.

So, the order of the statements is:

  • Line 10
  • Line 11
  • Line 1 to 3
  • Line 12
  • Line 4 to 6
  • Line 13
  • Line 7 to 9
  • Line 14

<h3>The value of x in between lines 11 and 12</h3>

On line 11, the function F(n) is called and executed.

This function multiplies 10 by 5 and assigns the product to x.

Hence, the value of x in between lines 11 and 12 is 50

<h3>The value of x in between lines 12 and 13</h3>

On line 12, the function G(n) is called and executed.

This function adds 25 to the global value of x (100) and assigns the sum to x.

Hence, the value of x in between lines 12 and 13 is 125

<h3>The program output</h3>

On line 13, the function H(n) is called and executed.

This function adds -25 to the global value of x (125) and assigns the sum to x.

The output is then printed on line 14

Hence, the output of the program is 150
