Question
You've been hired by Leibniz Lauders to write a C++ console application that approximates PI. Use a validation loop to prompt for and get from the user the number of terms to approximate PI to that is at least 1. Use the following Leibniz formula:
PI approximation = 4 * (1/1 – 1/3 + 1/5 – 1/7 + 1/9 – 1/11 + …)
The terms appear within the parentheses in the formula. A PI approximation to …
- One term is 4 * (1/1) = 4
- Four terms = 4 * (1/1 – 1/3 + 1/5 – 1/7) = 2.8952380952
- Seven terms = 4 * (1/1 – 1/3 + 1/5 – 1/7 + 1/9 – 1/11 + 1/13) = 3.2837384837
Use a for statement to calculate the approximation. Within the loop, use condition i % 2 == 0 to determine whether the loop iteration is even or odd. Format all real numbers to ten decimal places. Continue to prompt the user for terms until they enter a sentinel value of 99. Note that your prompt before the sentinel loop and at the end of the loop is a validation loop rather than a simple prompt. Loop the

- I am trying to write this program and I got stuck on page two. Please help me write this.arrow_forwardSummary In this lab, you complete a C++ program with the provided data files. The program calculates the amount of tax withheld from an employee’s weekly salary, the tax deduction to which the employee is entitled for each dependent, and the employee’s take- home pay. The program output includes state tax withheld, federal tax withheld, dependent tax deductions, salary, and take-home pay. Instructions Ensure the source code file named Payroll.cpp is open in the code editor. Variables have been declared and initialized for you as needed, and the input and output statements have been written. Read the code carefully before you proceed to the next step. Write the C++ code needed to perform the following: Calculate state withholding tax (stateTax) at 6.5 percent Calculate federal withholding tax (federalTax) at 28.0 percent. Calculate dependent deductions (dependentDeduction) at 2.5 percent of the employee’s salary for each dependent. Calculate total withholding (totalWithholding)…arrow_forwardIn C++ fill in the blanksarrow_forward
- C++ continued you already gave me the help from the first part. now they have added another set of instructions. original code used. Explanation Here I have created the main method. Inside the main method, I have taken input from the user for height and width and stored them into different variables. Next, I have created a loop that runs till it reaches the height of the rectangle. Inside the loop, I have created another loop that runs till the width of the rectangle. In the inner loop, I have printed the asterisk symbol. After the inner loop, I have used endl to give break and move the pointer to the new line. arrow_forward Answer C++ code: #include<iostream>using namespace std; int main(){ int height, width; // user input cin >> height >> width; // outer loop for(int i = 0; i < height; i++) { // inner loop for(int j = 0; j < width; j++) { //printing the * symbol cout << "*"; }…arrow_forwardNeed help figuring out this program and typing it in c++.arrow_forwardin the C++ version please suppose to have a score corresponding with probabilities at the end and do not use the count[] function. Please explain the detail when coding. DO NOT USE ARRAY. The game of Pig The game of Pig is a dice game with simple rules: Two players race to reach 100 points. Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions: roll - if the player rolls 1: the player scores nothing and it becomes the opponents turn. 2 - 6: the number is added to the player's turn total and the player's turn continues. hold - The turn total is added to the player's score and it becomes the opponent's turn. This game is a game of probability. Players can use their knowledge of probabilities to make an educated game decision.

- C++ Question Hello, Please create the correct code for the attached picture. Please create the code based on the given requirements. Please make sure it is working. Thank you!arrow_forwardThis assignment will give you practice on basic C programming. You will implement a few Cprogramsarrow_forwardUsing a Sentinel Value to Control a while Loop in C++ In this lab, you write a while loop that uses a sentinel value to control a loop in a C++ program that has been provided. You also write the statements that make up the body of the loop. The source code file already contains the necessary variable declarations and output statements. Each theater patron enters a value from 0 to 4 indicating the number of stars the patron awards to the Guide’s featured movie of the week. The program executes continuously until the theater manager enters a negative number to quit. At the end of the program, you should display the average star rating for the movie. Instructions Ensure the source code file named MovieGuide.cpp is open in your code editor. Write the while loop using a sentinel value to control the loop, and write the statements that make up the body of the loop. The output statements within the loop have already been written for you. Ensure you include the calculations to compute the…arrow_forward
