Decision Structures Calorie Calculator Assignment Overview This assignment will give you practice with numerical calculations, simple input/output, and if-else statements. Program Objective: In this exercise, you will write a program the calculates the Daily Caloric needs for weight lose diet. According to everydayhealth.com they recommend this daily caloric formula for a weight loss diet: BMR + Activity Level - 500 calories. Calories Calculator The Harris-Benedict equation estimates the number of calories your body needs to maintain your weight if you do no exercise. This is called your basal metabolic rate or BMR. The Calories needed for a woman to maintain her weight is: BMR = 655 + (4.3 * weight in pounds) + (4.7 * height in inches) - (4.7 * age in years) The Calories needed for a man to maintain his weight is: BMR = 66 + (6.3 * weight in pounds) + (12.9 * height in inches) - (6.8 * age in years) Next, the total daily caloric requirement is calculated by multiplying your BMR by your level of activity: • If the person is inactive (rarely exercise), then increase the calculated BMR 20%. • If the person is somewhat active, then increase the calculated BMR by 30% • If the person is active, then increase the calculated BMR by 40% • If the person is highly active then increase the calculated BMR by 50% Program Specification: Write a program that allows the user to input their weight in pounds, height in inches, and age in years. Ask the user to input the string “M” if the user is a man and “W” if the user is a woman. Use only the male formula to calculate calories if “M” is entered and use only the women formula to calculate calories if “W” is entered. Ask the user if he or she is: A. Inactive B. Somewhat active (exercise occasionally) C. Active (exercise 3-4 days per week) D. Highly active (exercise every day) • If the user answers “Inactive” then increase the calculated BMR by 20 percent. • If the user answers “Somewhat active” then increase the calculated BMR by 30 percent. • If the user answers “Active” then increase the calculated BMR by 40 percent. • Finally, if the user answers “Highly active” then increase the calculated BMR by 50 percent. • The program should then output the calculated daily Calories intake for this person in order to lose one pound per week by subtracting 500 calories from the calculated BMR. Input Errors • If the user enters an age either < 1 or > 100, instantly end the program with an error message. • If the user enters a height < 10 or > 100, instantly end the program with an error message. • If the user enters a weight < 10 or > 500, instantly end the program with an error message. • You can assume that the user does not type some non-numeric value. You don't have to test for this kind of non-numeric error. • If the user does not enter ‘M' for male calculation or 'W' for female calculation, instantly end the program with an error message. • If the user does not enter A, B, C, or D when prompted, instantly end the program with an error message. These limits must be defined as symbolic constants, which should be used throughout the program. Rules: • For this assignment you are limited to the Java features in Chapters 1 through 3; you are not allowed to use more advanced features to solve the problem. Please do not use Java features that are not covered in lecture or the textbook. • Use class constants as appropriate to represent important fixed data values in your program. • Follow programming guidelines and Java’s naming standards about the format of ClassNames, variableNames, and CONSTANT NAMES. • Notice that all real numbers output by the program are printed with no more than 2 digits after the decimal point. To achieve this, you may use the System.out.printf method. • Add the header to the class file and copy/paste the output that is produced by your program into the bottom of the source code file, making it into a block comment. • Class Name: Your program class should be called CalorieCalculator.

Write a Python program that reads in an amount in cents and prints the dollar amount in that and the remaining value in cents. For example, if the amount reads in is 360 (cents), the program would print 3 dollars and 60 cents. if the amount read in is 75 (cents), the program would print 0 dollars and 75 cents.

Cpp challenge

Description

The purpose of this challenge is to use the WHILE loop to control program flow. This challenge will use the WHILE loop in various ways.

Requirements

Write all your code for the following steps in one file.

1. Ask the user to enter a single string. Ask the user to enter an integer value for a variable called repetitions. Use a while loop to display this string (of your choice) repeated repetitions times, one string per line
2. Use a while loop to count and display all the integers from 1 to 20. Separate numbers with a space
3. Use a while loop to display all numbers divisible by 10 starting from 100 down to 0. Only show numbers divisible by 10. Separate numbers with a tab. TAB character is displayed using the \t escape sequence. (Remember that \n is a newline; use similarly)
4. Use a while loop to keep asking the user for an integer as long as positive numbers are being entered. For every positive number entered, show its value multiplied by 2. Once a negative number is entered stop asking and quit the loop
5. Use a while loop to keep asking for a string until a particular string is entered (for example, “bye”)

   Do Not Use

   You must use the WHILE statement. You may not use any other looping mechanism.

Sample Interaction / Output

Enter a string to be repeated: coffee
How many times to show? 5

// 1.) Insert a node with data 2 into this empty list

// 2.) Insert a node with data 4 at the end of the list.

// 3.) Insert a node with data 3 between the first and the last node.

// 4.) Insert a node with data 1 before the first node.

// 5.) delete the node with data 2

// 6.) delete the node with data 1

Write a Reverse Polish Calculator, RPN in JAVA

Each time an operand is encountered, two values are popped from this stack, the given operation is performed, and the result is pushed back onto the stack. Utilize Java generic Stack Class to implement this algorithm with four arithmetic operations: +, *, -, /.

Implement a class RPN with a single static method evaluate. This method should have the following signature:

            public static String evaluate(String expression)

It should split the passed expression into (a string array of) tokens by invoking split method of String class. This array can then be processed one element at a time (perhaps another method): each time a number is found – it is pushed on a stack. Each time an operation is found – two numbers are popped from the stack, the given operation is performed, and the result is pushed back on the stack. If the passed expression was a properly formed RPN, the last element on the stack represents the result. It should be returned as a string. If the given expression is not valid, evaluate should return a string denoting a syntax error.

Your main should continually ask the user to input a potential RPN string which would be passed to the evaluate method. In order to terminate the procedure, the user would input an empty string (carriage return).

Sample run of how it should look:

run:

Enter an RPN expression or to exit

2 3 4 +

7.0

extra junk ignored

Enter an RPN expression or to exit

2 3 4 + *

14.0

Enter an RPN expression or to exit

Syntax error

Enter an RPN expression or to exit

10 6 1 - /

Enter an RPN expression or to exit

5 4 3 / /

Create an application that calculates and displays the starting and ending monthly balances for a checking account and a savings account.

Welcome to the Account application Starting Balances Checking: $1,000.00 Savings: $1,000.00 Enter the transactions for the month Withdrawal or deposit? (w/d): w Checking or savings? (c/s): c Amount?: 500 Continue? (y/n): y Withdrawal or deposit? (w/d): d Checking or savings? (c/s): s Amount?: 200 Continue? (y/n): n Monthly Payments and Fees Checking fee: $1.00 Savings interest payment: $12.00 Final Balances Checking: $499.00 Savings: $1,212.00.

• Create interfaces named Depositable, Withdrawable, and Balanceable that specify the methods that can be used to work with accounts. The Depositable interface should include this method:

void deposit(double amount)

The Withdrawable interface should include this method:

void withdraw(double amount)

And the Balanceable interface should include these methods:

double getBalance()
void setBalance(double amount)

• Create a class named Account that implements all three of these interfaces. This class should include an instance variable for the balance.
• Create a class named CheckingAccount that inherits the Account class. This class should include an instance variable for the monthly fee that’s initialized to the value that’s passed to the constructor. This class should also include methods that subtract the monthly fee from the account balance and return the monthly fee.
• Create a class named SavingsAccount that inherits the Account class. This class should include instance variables for the monthly interest rate and the monthly interest payment. The monthly interest rate should be initialized to the value that’s passed to the constructor. The monthly interest payment should be calculated by a method that applies the payment to the account balance. This class should also include a method that returns the monthly interest payment.
• Create a class named AccountBalanceApp that uses these objects to process and display deposits and withdrawals.
• Use the Console class presented in chapter 7 or an enhanced version of it to get and validate the user’s entries. Don’t allow the user to withdraw more than the current balance of an account.

sorry to bother i really appreciate the help could you explain step by step please and thank you.
