Answer:

Hi!

var count =0; <em>//initialize count.</em>

var sevens =0 ; <em>//initialize sevens.</em>

while(count<100) <em>// loops while count is minor than 100. *counts never add 1 at the final of the loop, so this while is always true. </em>

{

<em>//Math.floor(x) round to the max Integer a number. Example : 45.90 -> 46.</em>

<em>//Math.random() returns a number between [0, 1).</em>

var roll1 = Math.floor(Math.random()*6+1); <em>//Gets a integer using Math.random(), adds 1, and round it withMath.floor() then saves in roll1.</em>

var roll2 = Math.floor(Math.random()*6+1); <em>//Gets a integer using Math.random(), adds 1, and round it withMath.floor() then saves in roll2.</em>

if(roll1 + roll2 == 7) <em> //If the sum of roll1 and roll2 is 7 adds 1 to sevens.</em>

sevens = sevens +1;

}

<em>//*count is not incremented, so while(count<100) -> always true.</em>

In this assignment, you will develop a C++ program and a flowchart that calculates a cost to replace all tablets and desktop com

Alexeev081 [22]

Answer:

Explanation:

The objective of this program we are to develop is to compute a C++ program and a flowchart that calculates a cost to replace all tablets and desktop computers in a business.

C++ Program

#include<iostream>

#include<iomanip>

using namespace std;

⦁ // Name:

⦁ // Date:

⦁ // Program Name:

⦁ // Description:

int main()

{

const double SalesTaxRate = .075, DiscountPercent = .10, FinanceCharge = .15;

const double TABLET = 320.00, DESKTOP = 800.00;

double total = 0.0, subTotal = 0.0,avg=0.0;

int numberOfTablets, numberOfDesktop;

cout << "-------------- Welcome to Computer Selling Company ------------------ ";

cout << "Enter number of tablets: ";

cin >> numberOfTablets;

cout << "Enter number of desktops: ";

cin >> numberOfDesktop;

subTotal = TABLET * numberOfTablets + numberOfDesktop * DESKTOP;

char choice;

cout << "Paying cash or financing: (c/f): ";

cin >> choice;

cout << fixed << setprecision(2);

if (choice == 'c' || choice == 'C')

{

cout << "You have choosen paying cash." << endl;

total = subTotal - subTotal * DiscountPercent;

cout << "Discount you get $" << subTotal * DiscountPercent<<endl;

cout << "Sales Tax: $" << SalesTaxRate * total << endl;

total = total + total * SalesTaxRate;

cout << "Total computers' Cost: $" << total << endl;

avg = total / (numberOfDesktop + numberOfTablets);

cout << "Average computer cost: $ " << avg << endl;

}

else if (choice == 'f' || choice == 'F')

{

cout << "You have choosen Finance option." << endl;

total = subTotal + subTotal * FinanceCharge;

cout << "Finance Charge $" << subTotal * FinanceCharge << endl;

cout << "Sales Tax: $" << SalesTaxRate * total << endl;

total = total + total * SalesTaxRate;

cout << "Total computers' Cost: $" << total << endl;

avg = total / (numberOfDesktop + numberOfTablets);

cout << "Average computer cost: $ " << avg << endl;

}

else

{

cout << "Wrong choice.......Existing.... ";

system("pause");

}

//to hold the output screen

system("pause");

} }

OUTPUT:

The Output of the program is shown in the first data file attached below:

FLOWCHART:

See the second diagram attached for the designed flowchart.

{

public static void main(String[] args)

{

Random randNum = new Random();

int people = 5;

int[] birth_Day = new int[365+1];

// setting up birthsdays

for (int i = 0; i < birth_Day.length; i++)

birth_Day[i] = i + 1;

int iteration;

// varying number n

while (people <= 100)

{

System.out.println("Number of people: " + people);

// creating new birth day array

int[] newbirth_Day = new int[people];

int count = 0;

iteration = 100000;

while(iteration != 0)

{

count = 0;

for (int i = 0; i < newbirth_Day.length; i++)

{

// generating random birth day

int day = randNum.nextInt(365);

}

// check for same birthdays

for (int i = 0; i < newbirth_Day.length; i++)

This is on zyBooks. Please write the code in C++, please!

poizon [28]

The program is an illustration of built-in functions

<h3>What are built-in functions?</h3>

They are named program statements that have a predefined purpose

<h3>The actual program</h3>

The program written in C++, where comments are used where required is as follows:

#include <iostream>

#include <cmath>

#include <ios>

#include <iomanip>

using namespace std;

int main (){

double x;

double y;

double z;

cin>>x;

cin>>y;

//This calculates the given expression

z = pow(sqrt(y),x);

cout << fixed<<setprecision(2);

cout<<z<<endl;

return 0;

}
