Complete function PrintPopcornTime(), with int parameter bagOunces, and void return type. If bagOunces is less than 3, print "Too small". If greater than 10, print "Too large". Otherwise, compute and print 6 * bagOunces followed by " seconds". End with a newline. Example output for ounces = 7:

42 seconds

#include <stdio.h>

void PrintPopcornTime(int bagOunces) {

}

int main(void) {
int userOunces;

scanf("%d", &userOunces);
PrintPopcornTime(userOunces);

return 0;
}

2. Write a function PrintShampooInstructions(), with int parameter numCycles, and void return type. If numCycles is less than 1, print "Too few.". If more than 4, print "Too many.". Else, print "N: Lather and rinse." numCycles times, where N is the cycle number, followed by "Done.". End with a newline. Example output with input 2:

1: Lather and rinse.
2: Lather and rinse.

Write a program that prompts the user to enter a 3 x 3 matrix of double values and tests whether it is a positive Markov matrix. There will be two methods which will be called from the main method: public static double [] [] createArray() 1. Creates a 3 by 3 two dimensional array of doubles 2. Prompts the user for values as shown in the sample run 3. Stores the numbers in the array in the order entered 4. Returns the array to the main method public boolean isMarkovMatrix(double [][] matrix) 1. Returns false if any value in the array is negative 2. Prints the sum of each column in the array 3. Returns false if any the sum of any of the columns is not equal to 1.0 4. Otherwise, it returns true. Sample Program running: Enter a 3 x 3 matrix by row 0.15 0.875 0.375 0.55 0.005 0.225 0.30 0.12 0.4 The sum of the columns 1.0 1.0 1.0 It is a Markov matrix Enter a 3 x 3 matrix by row -0.2 0.875 0.375 0.75 0.005 0.225 0.45 0.12 0.4 The sum of the columns 1.0 1.0 1.0 It is not a Markov matrix A response in Eclipse Java would be much appreciated.

PYTHON: Im writing a program to make a simple calculator that can add, subtract, multiply, divide using functions. It needs to ask for the two numbers from the user and will ask the user for their choice of arithmetic operation

1- subtract
2- add
3- divide
4- multiply

Complete the program to read in values from a text file. The values will be the scores on several assignments by the students in a class. Each row of values represents a specific student's scores. Each column represents the scores of all students on a specific assignment. So a specific value is a specific student's score on a specific assignment. The first two values in the text file will give the number of students (number of rows) and the number of assignments (number of columns), respectively.

For example, if the file contains:

3
4
9 6 10 5
2 2 0 0
10 10 9 10

then it represents the scores for 3 students on 4 assignments as follows:

The program should:

1) Read in the first two values to get the number of students and number of assignments. Create a two-dimensional array of integers to store all the scores using these dimensions.

2) Read in all the scores into the 2-D array.

3) Print the whole array, row by row on separate lines, using Arrays.toString() on each row of the array

3) Print the average of the scores on each assignment. For example, if the data is given in the above example, the output would be:

Array of scores:
[9, 6, 10, 5]
[2, 2, 0, 0]
[10, 10, 9, 10]

Average score of each assignment:
Assignment #1 Average = 7.0
Assignment #2 Average = 6.0
Assignment #3 Average = 6.333333333333333
Assignment #4 Average = 5.0

Starter Code:

import java.util.Scanner;
import java.io.File; //needed to open the file
import java.io.FileNotFoundException; //needed to declare possible error when opening file
import java.util.Arrays; //for the Arrays.toString() method

public class Scores {
public static void main(String[] args) throws FileNotFoundException {
//create a Scanner to get input from the keyboard to ask the user for the file name
Scanner keyboard = new Scanner(System.in);
System.out.println("What is the name of the file containing the scores?");
//create another Scanner to read from the file
String fileName = keyboard.nextLine();
Scanner fileScan = new Scanner(new File(fileName));
  
  
  
//TODO: read in the values for the number of students and number of assignments using the Scanner on the file
  
//TODO: create a 2-D to store all the scores and read them all in using the Scanner on the file

//TODO: print the entire array, row by row, using Arrays.toString()

Your task is to create a Java application that converts a specified amount of one currency into another currency for a user. The application must meet the following requirements:

1. Upon execution, the application shall display a brief welcome message to the user to let her know she is running the currency converter application.

2. The application shall allow a user to convert amounts between any two of the following currencies: United States Dollars (USD), British Pounds (GBP), Swiss Francs (CHF), and Indian Rupees (INR).

3. The application shall prompt the user for the following input: the currency she wishes to convert from (“source currency”); the amount of currency to be converted (“requested amount”) as either a decimal or a whole number (e.g., 21.45, 1.748484, or 34); and the currency she wishes to convert to (“result currency”).

4. The application shall limit the amount of the currency to be converted to no more than 1,000,000 (one million) units of that currency; if the user attempts to enter an amount larger than this number, the application should return a message alerting the user that she has exceeded the maximum amount, and prompt her to enter another amount.

5. The application shall handle incorrect user input (e.g., if the user inputs a character or string for the “requested amount” value) and prompt the user for correct input.

6. The application shall prevent the user from attempting to convert to a “result currency” that is the same as the “source currency” (e.g., the user should be prevented from converting United States Dollars to United States Dollars).

7. The application shall output the following information: the amount of the “result currency” that is equivalent to the “requested amount” in the “source currency”; this amount shall be returned as a decimal figure rounded to two decimal places (e.g., 67.49).

8. The application shall allow the user to exit the program at any time by accepting input of an exit character (for example “Q” for quit) to terminate the program.

9. After the user has successfully converted a currency, the application shall prompt the user to either perform another conversion or terminate the program.

10. Upon program termination, the application shall display an exit message to the user.

Program Data Your program should use the following data for currency conversions.

Fitness Task:
public interface Fitness

• public Muscle [ ] muscleTargeted() A method that returns the muscle that is going to be affected by the fitness. Note that the return type of the method is Muscle. A human body has a finite number of muscle parts that can be affected by fitness exercises. Define an enum datatype called Muscle with the follwoing member values Abs,Back,Biceps,Chest,Arms,Glutes,Shoulders,Triceps,Legs,Cardio
• public String description() a method that returns a short decription of the fitness type.

Anaerobic Task:

(10pts) Anaerobic is a Fitness and we cannot give the actual implementation for the methods muscleTargeted() as we don't know the actual Anaerobic exercise. The descripton() method returns the string Anaerobic means "without oxygen.". Note that Anaerobic is a good candidate to be abstract class.

Define class yoga which are Anaerobic fitness exercises. Use the following table to define the classes. The classes also have:

• @Override public String description() returns the name of the respective classes.

public class Profile

Assume the weight is in kgs, height in meters and gender is enum data type called Gender. In addition, this class must contain:

• public Profile(int age, double height, double weight, Gender gender) A constructor which accepts the age,weight, height, and gender.
• provide getters and setters for height , weight and gender.

public class DailyExercise

• public DailyExercise(ArrayList exerciseList, int duration, double calorieTarget, Profile profile) A constructor which accepts the list of exercises, number of minutes to workout and the amount of calories to be burnt.
• public DailyExercise(ArrayList exerciseList, Profile profile) A constructor which sets duration to 1 hour and calorieTarget to 500.
• public void addExercise(Fitness ex) add a new Fitness in the exerciseList.
• public void removeExercise(Fitness ex) removes an Exercise from the exerciseList.If the exercise does not exist, it will leave the exerciseList unchanged.
• public void setExerciseList(ArrayList list) A setter method which sets the exerciseList of the DailyExercise.
• public void setDuration(int duration) A setter method which sets the duration of the DailyExercise.
• public void setCalorieTarget(double target) A setter method which sets the amount of calorie to be burnt of the DailyExercise.

• public ArrayListgetWeeklyExercises(Intensity intensity) a method that returns a list of DailyExercises that the user should do in order to meet the targeted calorie loss. The method evenly distributes the calorie loss over the number of days the user plans to workout. This method accepts the intensity of the exercises.
• public ArrayListgetWeeklyExercises() a method that returns a list of DailyExercises that the user should do in order to meet the targeted calorie loss. Note that the DailyExercise suggessions include the duration (minutes) the user should work out towards the targeted calorie loss.
• public String targetedCalorieLoss(double targetWeight, int withInDays) this method returns the string that contains a suggestion on how to loss the targeted weight within the specified number of days. . If the target weight is greater than the actual weight of the user, the method throws a TargetWeighException. You need to define a TargetWeightException that extends Java's Exception class and displays the string "Only works to lose weight".

(Python)####But, what if we need just a sequence without brackets, i.e., we want to have
####1, 2, 3, 4,... and not [1, 2, 3, 4, 5, ...]?
####We can do this:
##print(*accum, sep=", ") ## *accum 'unpacks' the list accum.

Ask for the left and the right range bounds with input:
##
##leftB = int(input('Enter the left bound: '))
##rightB = int(input('Enter the right bound: '))
## and if (rightB - leftB) is odd then print the list of the numbers in this range,
## if (rightB - leftB) is even then print just sequence (no brackets []) of the numbers in this range.
