Cant figure out why my out is wrong for my c++ program.

for example if the initial value is 100, the intrest rate is 10%, and it takes 6 months for maturity the output should be $105 but instead it outputs 101.657 please help.

#include <iostream>

#include <cmath>

using namespace std;

struct account

{

double balance;

double interest_rate;

int term;

};

void info(account& accountinfo);

int main(void)

{

double calc1, calc2, calc3;

account accountinfo;

info(accountinfo);

calc1 = accountinfo.interest_rate / 100;

calc2 = accountinfo.term / 12;

calc3 = (accountinfo.balance * pow (1 + calc1 / 365, 365 / accountinfo.term));

cout << " " << endl

<< " The balance of your CD account after it has matured in " << accountinfo.term << " months " << endl

<< " at a interest rate of " << accountinfo.interest_rate << " percent will be " << calc3 << endl

<< " " << endl;

return 0;

}

void info(account& accountinfo)

{

cout << " " << endl

<< " This program calculates the value of a CD after maturity. " << endl

<< " " << endl

<< " Enter the balance on the account. " << endl;

cin >> accountinfo.balance;

cout << " " << endl

<< " Enter the interest rate for the CD. " << endl

<< " " << endl;

cin >> accountinfo.interest_rate;

cout << " " << endl

<< " Enter the term for the CD to achieve maturity (in months). " << endl

<< " " << endl;

cin >> accountinfo.term;

Make sure you complete the parts in numerical order. Notice that part 4 occurs in the code after part 5. As stated in the part 5 comments, you should complete part 4 before part 5 because part 5 has a step that says: "// declare and instantiate an ActionListener" This ActionListener must be an object of the private inner button handler class that you write in part 4. The 5 parts of 12-2 each have helpful comments. The comments will guide you about what code to write. Button instantiation -------------------- Suppose you define a button as follows: JButton three; To instantiate it with its label set to "3 x 3", you would write: three = new JButton("3 x 3"); Part 2 ------ Note that the Game class inherits from JPanel. Therefore, the panel you are asked to add to the center of the content pane is the "game" object. Part 4 button handler --------------------- You have to create a private inner class to handle events from any of the three game setup buttons. This course is cumulative. Each new chapter builds on previous chapters. Week 4 had a video called Java GUI Button Components. The code for that video was supplied in a folder in week 4. Here is a section of the code shown in that video: private class CommandHandler implements ActionListener { public void actionPerformed(ActionEvent e) { Object source = e.getSource(); if (source == btnDisplayTrees) { displayTrees(); return; } if (source == btnDisplayWater) { displayWater(); return; } if (source == btnPackWindow) { packWindow(); return; } if (source == btnReset) { reset(); return; } } etc. The above code shows a private inner class named CommandHandler that handles button events. You can name your button handler whatever you want, such as ButtonHandler, but you must use the same name in part 5 after the comment: // declare and instantiate an ActionListener In the above video example, there is an if test for each button event. Each of the if blocks does something and then returns. In your button handler, you also have to do a certain thing for each button as specified in the comments. However, you cannot then simply return because validate() must be called at the end of the function--no matter which button was clicked. There are 2 simple ways to achieve this: 1) Use nested if/else's followed by the validate() call, or 2) Call validate() after each button's processing and then return from each one as in the video example. Part 4 setUpGame() ------------------ The part 4 comments include: // depending on which button was pressed, // call the setUpGame method of the Game class // with arguments 3, 4, or 5 // the API of that method is: // public void setUpGame(int nSides) To call a function we need an object of its class. Does our framework code have an object for us of type Game? Looking near the beginning of the NestedLayoutPractice class that we are in, you will see the following declaration: private Game game; So, game is an object reference of type Game that we can use. Your framework starting code already includes the following line of code in part 2: game = new Game(3); // instantiating the GamePanel object This is where the game object is actually created. It is passed a value of 3 in the constructor call. This will cause the game to be created with 3 rows by 3 columns of numbered squares. Now back to your part 4 handler comments. The comments say to change the game setup as instructed based on which button was clicked. If you look at the example user interface you will see that there are 3 buttons to change the game to 3 x 3, or 4 x 4, or 5 x 5 squares. You should have already declared these buttons in part 1 and created them in part 3 as instructed. In part 4, your event handler function must handle when each of the buttons is clicked. If, for exaample, the 4 x 4 button is clicked, then you should have the following line of code for that event: game.setUpGame(4); Don't overthink this. It is a simple function call using the game object, its setUpGame() method, and a literal parameter of 4. At the end of the function, call

i need the pseudocode and python program for the following problem.

Besides the user entering the number of books purchased this order, they are asked for the number of

points earned for the year before this order and the number of books ordered this year before this order.

There are bonus points awarded based on the number of books previously ordered and number ordered

now. These points should be added to the variable points:

Current order: 0 Previous Orders > 10 Add 1 to point total

Current order: 1, 2, or 3 Previous Orders > 10 Add 2 to point total

Current order: > 3 Previous Orders > 10 Add 5 to point total

// main module

Module main()

// Local variables

Declare Integer points

Declare Integer yearlyBooks

Declare Integer books

// Get numbers

Call getYearlyPoints(points)

Call getYearlyBooks(yearlyBooks)

Call getBooksPurchased(books)

// Display points earned

If books == 0

Display "0 points earned this order"

// Bonus check here

Display “Total points for the year”, points

Else If books == 1

Display "5 points earned this order"

Set points = points + 5

// Bonus check here

Display “Total points for the year”, points

Else If books == 2

Display "15 points earned this order"

Set points = points + 15

// Bonus check here

Display “Total points for the year”, points

Else If books == 3

Display "30 points earned this order"

Set points = points + 30

// Bonus check here

Display “Total points for the year”, points

Else

Display "60 points earned this order"

Set points = points + 60

// Bonus check here

Display “Total points for the year”, points

End If

End Module

// The getYearlyPoints module gets number of books purchased

// this year before this month

// and stores it in the number reference variable.

Module getYearlyPoints (Integer Ref number)

Display "How many points have you earned so far this year?"

Input number

End Module

// The getYearlyBooks module gets number of books purchased

// this year before this month

// and stores it in the number reference variable.

Module getYearlyBooks (Integer Ref number)

Display "How many books did you buy this year before this month?"

Input number

End Module

// The getBooksPurchased module gets number of books purchased

// this month

// and stores it in the number reference variable.

Module getBooksPurchased (Integer Ref number)

Display "How many books did you buy this month?"

Input number

End Module

NOTE: Using the variable name number in all three modules is perfectly legal

because they are each “local” to the module. In the first module the value of

number is returned to the variable points. In the second module it is returned to

the variable yearlyBooks. In the third it is returned to books.

Java - Create a program that simulates a slot machine. When the program runs, it should do the following: - Ask the user to enter the amount of money he or she wants to enter into the slot machine. - Instead of displaying images, have the program randomly select a word from the following list: Cherries, Oranges, Plums, Bells, Melons, Bars (To select a word, the program can generate a random number in the range of 0 through 5. If the number is 0, the selected word is Cherries, if the number is 1, the selected word is Oranges, and so forth. The program should randomly select a word from the list three times and display all three of the words.) - If none of the randomly selected words match, the program informs the user that he or she has won $0. If two of the words match, the program informs the user that he or she has won two times the amount entered. If three of the words match, the program informs the user that he or she has won three times the amount entered. - The program asks if the user wants to play again. If so, these steps are repeated. If not, the program displays the total amount of money entered into the slot machine and the total amount won.

What are the main challenges for IOT management?

Python programming:

Instructions:

• The python program should respond to user input on a command line
• Below are the four options
  - if the user input is A, the program will quit
  -if the user input is B, the program will display the number of times the prompt has been displayed
  -if the user input is C, will display whatever is stored.
  -if the user inputs something else, it will store that user input as a string and append it to the already stored data.

Write a C++ program that asks the user for the values of three resistances. We suppose that the user will not enter a negative value. The program then asks the user whether he has a series or parallel montage. The user will answer with S or s for series and P and p for parallel. (If the user enters a wrong answer, he will see a message on the screen alerting him, and the program will end.) Finally, the program displays the total resistance value. (Note that for a parallel circuit, if one of the resistances is zero, the total resistance is zero)

PHP Language

I have XAMPP and I don't know how to display my PHP code. For instance, when I create a basic HTML webpage I just open the code into a web browser and it shows me a basic web page. When I try to show a PHP calculation it doesn't show. What are the steps in displaying my PHP doc?

Write a method, twoSumSorted2, that solves the following variant of the Two-Sum problem:

Given a sorted array of integers where each element is unique and a target integer, return in an Array List, the indices of all pairs of elements that sum up to the target. Each pair of indices is also represented as an Array List (of two elements). Therefore, the method returns an Array List of an Array List of size 2. If no pair in the input array sums up to the target, then the method should return an empty list.

public class Hw2_p1 {
  
   // HW2 Problem 1 Graded Method
   public static ArrayList<ArrayList<Integer>> twoSumSorted(int[] A, int target) {
       ArrayList<ArrayList<Integer>> ans = new ArrayList<>();
      
       // Your code starts
      
      
       // Your code ends
      
       return ans;
   }

  
   // Test driver for twoSumSorted2
   public static void main(String[] args) {
      
   }

}

The following are two sample runs:

Input:   ? = [−7, −5, −2, 0, 1, 6, 7, 8, 9],   ?????? = 1

Return value:   [0,7], [1, 5], [3, 4]

Explanation: The pairs in the input array that sum up to 1 are [−7, 8], [−5, 6] and [0, 1]. Their indices are [0, 7], [1, 5] and [3, 4] respectively.

Input:   ? = [−2, 0, 1, 6, 7, 8],   ?????? = 3

Return value:   [ ]

Explanation: No pair of elements in input array sums up to 3. The returned list is thus empty.

Your method must have time complexity ?(?), where ? is the length of the input array.
