1. In C++, Mrs. Jones wishes to computerize her grading system. She gives 5 tests but only counts the 4 highest scores. Input the 5 test scores and output the average of the highest four. And using the following grading scale, 90-100 A, 80-89 B, 70-79 C, 60-69 D, and below 60 F, output the student’s letter grade. After creating this code, Modify the above to calculate the grade for all students in the class. The first input value will be the number of students in the class. You will then need to use a loop to input the students’ names as well as their 5 grades. Inside the loop (after calculating the average for the student) you will need to add each student’s average to a sum variable because at the end, you will need to print out the class average as well as each students’ names and letter grades.

Given a stack S and an element x, write a recursive algorithm that returns True if x is in S, or False otherwise. Note that your algorithm should not change the content in S. What is the time complexity of your algorithm?

Write a loop that sets newScores to oldScores shifted once left, with element 0 copied to the end. Ex: If oldScores = {10, 20, 30, 40}, then newScores = {20, 30, 40, 10}.

--------------Code Below-----------

#include <iostream>
using namespace std;

int main() {
const int SCORES_SIZE = 4;
int oldScores[SCORES_SIZE];
int newScores[SCORES_SIZE];
int i;

for (i = 0; i < SCORES_SIZE; ++i) {
cin >> oldScores[i];
}

/* Your solution goes here */

for (i = 0; i < SCORES_SIZE; ++i) {
cout << newScores[i] << " ";
}
cout << endl;

return 0;
}

Given a positive integer n, write a recursive algorithm that returns the number of the digits in n. For example, if the given number n is 12345, the algorithm should return 5. What is the time complexity of your algorithm?

Fill in the code only using pointer variables

#include

using namespace

std; int main() {

int longside; // holds longside (length)

int wideside; // holds wideside(width)

int total; // holds total (area)

int *longsidePointer = nullpointer; // int pointer which will be set to point to length

int *widthPointer = nullpointer; // int pointer which will be set to point to width

cout << "Please input the longside of the rectangle" << endl;

cin >> longside;

cout << "Please input the wideside of the rectangle" << endl;

cin >> wideside;

// Fill in code to make longsidePointer point to longside(length) (hold its address)

// Fill in code to make widesidePointer point to wideside(width) (hold its address)

total = // Fill in code to find the total(area) by using only the pointer variables

cout << "The total is " << total << endl;

if (// Fill in the condition longside(length) > wideside(width) by using only the pointer variables)

cout << "The longside is greater than the wideside" << endl;

else if (// Fill in the condition of wideside(width) > longside(length) by using only the pointer variables)

cout << "The wideside is greater than the longside" << endl;

else

cout << "The wideside and longside are the same" << endl;

return 0;

}

}

The user will input a dollar amount as a floating point number; read it from input using a Scanner and the .nextDouble() method. Convert the number of dollars into a number of whole (integer) cents, e.g., $1.29 = 129 cents. Determine and output the optimal number of quarters, dimes, nickels, and pennies used to make that number of cents.

Ex: if the input is

1.18

The output should be

4
1
1
3

for 4 quarters, 1 dime, 1 nickel, 3 pennies.

Hints

1. Remember that a double multiplied by an int gives back a double. You will need to cast the result to int if you want to do integer arithmetic, like modulo.
2. % is modulo.
3. There is no "f-string" equivalent in Java.

(STARTING CODE)

import java.util.Scanner;

public class Change {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);

/* Type your code here. */
}
}

Given a stack S and an element x, write a recursive algorithm that returns True if x is in S, or False otherwise. Note that your algorithm should not change the content in S. What is the time complexity of your algorithm?

How an isolated workspace is provided by docker to keep applications on the same host or cluster isolated from one another? Give a proper answer.

Question 1 (20pts):

Create a dictionary of the form {“Jordan”: “Basketball”, “Federer”: “Tennis”, “Ronaldo”: “Football”} and perform the following actions

• Print all the keys in the dictionary
• Print all the values in the dictionary
• Iterate through the dictionary and print the value only if the key is “Federer”
• Iterate through the dictionary and print the key only if the value is “Football”

Question 2 (15pts):

List1 = [3, 4, 5, 20, 5]

List2 = [4, 9, 6, 2, 10].

Using list comprehensions, print the output if you multiply the i-th element of each list

Question 3 (15pts):¶

Dic1 = {"John":10, "Joe":15}

• Check whether “John” is one of the keys
• Remove the key “Joe” along with its associated value
• Add another key and value pair - “Jean”: 40

Question 4 (15pts):

• Write a user defined function to find the highest of the three numbers: 30, 10 and 20. The highest number should be printed. Note: The function has to be user defined.

• With a given integral number n, write a program to generate a dictionary that contains key value pairs such as i: 2^i, and i takes values between 1 and n (both included). Then print the dictionary.

Suppose the following input is supplied to the program:

4

Then, the output should be:

{1: 2, 2: 4, 3: 8, 4: 16}

Question 5 (20pts):

• Using list comprehensions, print all the values between 1 and 10 that are divisible by 2. The output should be [2, 4, 6, 8].

• By using list comprehension, please write a program to print the list after removing the value 24 in [12,24,35,24,88,120,155].

Question 6 (15pts):

Remove the last value in [12,24,35,24,88,120,155] consecutively and print the removed value in each removal.

using java Design a class named Triangle that extends GeometricObject. The class contains: • Three double data fields named side1, side2, and side3 to denote three sides of a triangle. • A no-arg constructor that creates a default triangle with default values 1.0. • A constructor that creates a triangle with the specified side1, side2, and side3. In a triangle, the sum of any two sides is greater than the other side. The Triangle class must adhere to this rule and throw an IllegalTriangleException object if a triangle is created with sides that violate the rule • The accessor methods for all three data fields. • A method named getArea() that returns the area of this triangle. • A method named getPerimeter() that returns the perimeter of this triangle. • A method named toString() that returns a string description for the triangle. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.

Rectangle Class in C++

Create a Rectangle class that has two data members: length_ and width_. Create the corresponding accessor and mutator functions to access and change both data members.

Create a member function area that returns the area of the Rectangle object. Finally, create a function longest_rectangle that accepts two Rectangle objects as parameters and returns the Rectangle object with the longer length.

Write the Rectangle class and the longest_rectangle function prototype in rectangle.hpp. Take note that longest_rectangle is not a member function of the Rectangle class. Provide the function's implementation in rectangle.cpp.

Complete main.cpp according to the comments provided in the file.

Sample Output:

Rectangle 1
Please enter the length: 2
Please enter the width: 3
Rectangle 1 created with length 2 and width 3
The area of Rectangle 1 is: 6

Rectangle 2
Please enter the length: 4
Please enter the width: 5
Rectangle 2 created with length 4 and width 5
The area of Rectangle 2 is: 20

The longest rectangle has a length of 4, a width of 5, and an area of 20.

Objective: Only attempt this assignment after thoroughly reading Chapter 4 of the Visual Basic text. The objective of the assignment is to write a program in Visual Basic that applies decision logic within the program. Another objective is to work through any syntax errors encountered (debugging) to develop a correct solution that is free of errors.

Description: Create a working Visual Basic solution using the Visual Studio IDE that accepts two numbers from the user and displays one of the following messages: First is larger, Second is larger, Numbers are equal. Provided your logic from last week was correct, you can use the pseudocode and flowchart from last's week's assignment to help you code your solution. After you output one of the three messages, calculate the average of the 2 numbers and display it for the user.

Requirements: For full credit, make sure that you create your program using Visual Studio. Also make sure that the program compiles (builds) successfully and without any errors. To test the logic of your program, make sure to try many different combinations of numbers. Ensure that in addition to displaying one of the three messages to the user that you also calculate and display the average as described.
