Double width is read from input and area is the square of width. Perform the following tasks: Output width with a maximum of eight digits, showing the decimal point and any trailing Os. Then, output **. Output area in fixed-point notation with a maximum of four digits in the fraction. Then, output" • Output area in scientific notation with a maximum of four digits in the fraction. End with a newline. Ex: If the input is 6.25, then the output is: 6.2500000 39.0625 3.90630+01 Note: cout << showpoint shows the decimal point and any trailing Os even when the fraction (after the decimal point) is zero. 1 #include 2 #include 3 using namespace std; 5 int main() (. 6 7 8 9 10 11 12 13 14 15 16 17 18) double width; double area; cin>> width; area width cout << fixed <

A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours in humans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 24 hours. Use a string formatting expression with conversion specifiers to output the caffeine amount as floating-point numbers. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print(f'{your_value: .2f}') Ex: If the input is: 100 the output is: After 6 hours: 50. 00 mg After 12 hours: 25.00 mg After 24 hours: 6.25 mg Note: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg.

Create an algorithm that will prompt a user to answer the following question. “Do you want to convert the Fahrenheit temperature to Celsius?’ While the user answers yes, the algorithm will prompt a user for a Fahrenheit temperature, convert the Fahrenheit temperature to Celsius, and print the Celsius temperature. Write the algorithm using pseudocode, and create a desk check using at least one set of test data. The formula used to convert Fahrenheit to Celsius is: °C = (°F - 32) / 1.8 Example: 68 °F Celsius = (68-32)/1.8Celsius = (36)/1.8Celsius = 20
Take input a string and create a new string where 'if' is added to the front of the input string. If the string already begins with 'if', return the string unchanged.Sample Input:"if else""else"Sample Output:if elseif else

First, read in an input value for variable numVals. Then, read numVals integers from input and output each on the same line with ": " between each value. End with a newline. Note: ": " should not be at the beginning or end of the output. Ex: If the input is 4 -20 80 60 -10, then the output is: -20: 80: 60: -10 1 2 3 4 5 6 7 8 9 10 #include <iostream> using namespace std; int main() { intnumVals; /* Your code goes here */ return0; }
Given two numbers that represent the lengths of a right triangle's legs (sides adjacent to the right angle), output the length of the third side (i.e. hypotenuse) with two digits after the decimal point. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('Hypotenuse: {:.2f}'.format(c)) Ex: If the input is: 3.0 4.0 the output is: Hypotenuse: 5.00
Ask the user for an account balance. Show, in descending order, all the accounts that have a balance greater than what the user input. Each entry is int, string, long, double, boolean (name length, name, credit card number, balance, cashback). i need the display produced from the code to be in descending order, it is displaying the opposite it also needs to produce yes or no instead of boolean true/ false this is my current code: import java.io.*;import java.util.*; public class AccountBalance { public static void main(String[] args) { Scanner keyboard = new Scanner(System.in); System.out.println("Enter a balance"); double input = keyboard.nextDouble(); // Create an ArrayList to store Account objects ArrayList<Account> accounts = new ArrayList<>(); try { // Open the binary file for reading DataInputStream inputstream = new DataInputStream(new FileInputStream("accounts-with-names.dat")); //…
