Write a function that accepts a line of text and a single letter as input (case insensitive) and returns the number of times the letter is the last character of a word. Note your program should be able to handle different cases. And check if the user input is a single letter.

Suppose your work for the university of Michigan. The university wants to implement an email spam filter. So use the mbox.txt file that we used in class, build a filter system that filters emails into several categories of security levels: level 1 is the email from Uof M (@ umich.edu), level 2 is the email from other North American universities (@ xyz.edu), level 3 is the email from other educational institutions around the world (.uk, .za, etc.), and level 4 is the email from other email services (g m ail, etc). Please print out these 4 levels and also list all the senders (only those in the "From" lines) in each category. Example output: Level 1: zqian@ umich.edu Level 2: louis@ media.berkeley.edu ray@ media.berkeley.edu mmmy@ indiana.edu Level 3: antranig@ caret.cam.ac.uk david.horwitz@ uct.ac.za Level 4: gopal.ramasammycook@ g mail.com

Assume you are creating a database for IS paint store. The database needs to support the following business functions. • Allow customers to browse the inventory. Customers want to search by paint types and colors. Customers also wants to know pricing information. • A customer can be a regular customer (e.g., home owner), or a contractor or painting professionals. Different customers can get different discounts for the same type of paint. We assume each customer can get the same discount for all types of products in this store. • Allow the employees of the IS paint store to record the information of a sale. Each sale has a sale date, sale amount (colors, number of gallons, etc.), and total payment due (including prices and sales tax). • A customer can finance for large sales. For simplicity, we only consider the case where each customer can have 12 installments of payments with 0% interest rate. For example, if the total payment amount is $120, a customer can choose to pay $10 each month for 12 months to complete the payment. For each transaction like this, we should allow the employees to record the type of payment, the next payment date, amount due. If a customer misses a payment, employees of the store need to send a notice to the customer to charge a fine. The data model consists of 4 entities: Inventory, Customer, Transaction, and Transaction_Detail. Please see the solutions for assignment 1 for details of the sample design. Please answer the following questions. 1. Draw the entities and relationships using ER diagram notations. Please specify relationships with cardinalities. You may use any drawing tools to print it out, or draw it clearly on the paper. 2. Answer why you do not want to create relationships for customer search inventory, employee records transaction, and employee sends notice to customer.

Write an application with five classes Vehicle, Car, Bus, Truck, and Tester class with main method in it.

The following characteristics should be used: make, weight, height, length, maxSpeed, numberDoors, maxPassenges, isConvertable, numberSeats, maxWeightLoad, and numberAxels.

Characteristics that are applicable to all vehicles should be instance variables in the Vehicle class. The others should be in the class(s) where they belong.

Class vehicle should have constructor that initializes all its data. Classes Car, Bus, and Truck will have constructors which will reuse their parents constructor and provide additional code for initializing their specific data.

Class Vehicle should have toString method that returns string representtion of all vehicle data. Classes Car, Bus, and Truck will override inherited toString method from class vehicle in order to provide appropriate string representation of all data for their classes which includes inherited data from Vehicle class and their own data.

Class Tester will instantiate 1-2 objects from those four classes (at least five total) and it will display the information about those objects by invoking their toString methods.

You have been working with the arrays for the past few weeks and you have learned their limitations.

In this assignment, you will be using a new data structure, HashMaps, to repeat Assignment 8.3.

Main Method

• (5 points) Declare and initialize an HashMap with values of type of type Employee, and keys of type integer. In a while loop, keep initializing objects of type Employee, storing them in the HashMap, and allow the user to enter ID, salary, and leaveDays of the each employee one by one and in one line. Once the user entered a -1, stop initializing new employees, and print "You entered [actual length of array] employees. Thank you!"
• (5 points) In a foreach loop, go through every Employee object in the HashMap, and calculate their monthly payments, using the calcMonthlyPayment() method.
• (10 points) In a second foreach loop, go through every Employee object in the HashMap, and call their makePayment method only if their leaveDays is NOT higher than 21.

Sample Run: For the below input:

1 120000 6
2 50000 25
3 140000 4
4 112000 22
5 130000 4
-1

The output will be:

You added 5 employees! Thank you!
Monthly payment for employee 1 is calculated.
Monthly payment for employee 2 is calculated.
Monthly payment for employee 3 is calculated.
Monthly payment for employee 4 is calculated.
Monthly payment for employee 5 is calculated.
A payment of 10000 was made to employee 1.
A payment of 11666 was made to employee 3.
A payment of 10833 was made to employee 5.

Create a Java class named Trivia that contains three instance variables, question of type String that stores the question of the trivia, answer of type String that stores the answer to the question, and points of type integer that stores the points’ value between 1 and 3 based on the difficulty of the question.

Also create the following methods:

1. getQuestion( ) – it will return the question.
2. getAnswer( ) – it will return the answer.
3. getPoints( ) – it will return the point
4. setQuestion( String ) – sets the value of the question variable
5. setAnswer( String ) – sets the value of the answer variable
6. setPoints( int ) – sets the value of the points variable
7. Constructor to initialize the instance variables.
8. Overload Constructor to set the instance variables.
9. Add any other methods you need such as equal( ), toString( ), display( ), calcPoints( )...

Create Java application that contains a main method that plays a simple Trivia game. The game should have 5 questions. Each question has a corresponding answer and point value between 1 and 3. Implement the game using an array of 5 Trivia objects.

Next, open a binary file and store those 5 Trivia objects into a binary file then close the file. Open the file again to read each question one at a time and store them into an array of objects.

Randomly, display a question and allow the player to enter an answer.

If the player’s answer matches the actual answer, the player wins the number of points for that question. If the player’s answer is incorrect, the player wins no points for the question. Make sure the answer is not case sensitive and it is only one word or two words at most. The program should show the correct answer if the player is incorrect. After the player has answered all five questions, the game is over and your program should display the player’s total score.

You need to turn in the code, a sample output of those 5 questions, the player's answers and the total.

Make sure it is readable, formatted and commented.

in C++ (Please do steps 1-11)

1 ) Create a file that contains your grades and the type of assement (you can just create the file or write the file in the program)

A = Assignment

E = Extra Credit

L - Lab

Q = Qui

M = Mid

Example:

L 20

L 20

L 20

Q 10

A 18

E 9

Q 10

L 20

Q 10

L 20

Q 10

L 20

M 85

2 ) create 3 float arrays with 12 positions (one array for labs one array for qui and one array for assignments) (should be in main)

3 ) create float variables for extra credit, mid exa, attendance and fina exa (should be in main)

4 ) Read the file and place the assessments in their appropriate arrays or variables (should be in main)

5 ) Calculate the average grade for qui, assignments and labs using the following formula(should be in calculate function)

= <average> = (<sum>/(<number_of_grades>*<possible_points>))*100

6 ) Calculate the mid grade using the following formula (should be in main)

= <mid> = <mid>+<extra_credit>

7 ) Give yourself an average of 100 for attendance and pick a grade for your final (should be in main)

8 ) Print the average grade for each assessment type: (should be in main)

:

Example:

Labs: 100

Qui: 100

Assignments: 90

Mid Exa: 94

Fina Exam: 100

Attendance: 100

9 ) Multiply the average by the assessment percentage (should be in main)

Assessment percentage for each assessment type:

Labs: .15

Qui: .05

Assignments: .15

Mid: .25

Fina: .35

Attendance: .05

10 ) Calculate your fina grade (should be in main)

= <current_grade> = <lab_perecent>+<qui_perecent>+<assignment_perecent>+<mid_perecent>+<fina_perecent>+<attendance_perecent>

11 ) Print your fina grade in the following format: (should be in main)

Current grade:

Example

Current grade: 97

In this project, you will create a Visual Basic solution to perform customer billing at the Cyberian Internet Cafe. Please see below for the detailed instructions. You will create the project and then design a form using the image provided here. Then, add the necessary code to do the billing calculation and display the amount due.

Instructions

In this case, you will create a Visual Basic solution that performs customer billing for the Cyberian Internet Café. The Cyberian Internet Café provides Internet access to its customers on an hourly basis. One hour of Internet access costs $12.00. You will create a solution with a splash screen, which is an application that calculates the total cost for a customer, using the image file included in the downloaded files.

Step 1: Create the Project:

Create a Visual Basic Project using the project name “InternetCafe”.

Step 2 – Design the Form:

Design the form shown in Figure 1. You will need three button controls, three text boxes, one picture box control, and five label controls. Name your controls as shown in Table 1, and set the properties as indicated.

Table 1 – MainForm Controls and Their Property Values

Step 3 – Add the image to the project’s Debug folder:

Copy the image files (J0195384.jpg) that you downloaded as part of this Case’s files into the following folder of your project:

C:\InternetCafe\ InternetCafe\bin\Debug

(If your drive letter is different than C:, use your drive letter.)

Step 4 – Add code to perform the calculation and display the amount due:

1. In the form’s Declarations section, declare a constant named HOURLY_RATE and set its value to be 12.00.
2. In the clearButton’s Click event, add code to clear all of the text box controls and the amountDueLabel control.
3. In the calculateButton’s Click event, declare two Single variables named hours and amount, and a Boolean variable name isConverted. Use the TryParse method to assign the value in the hoursTextBox control to the hours variable, storing the result from the TryParse method in the isConverted variable. Do the calculation using the hours and the hourly rate, and store the result in the amount variable. Display the amount value, formatted as currency, in the amountDueLabel control.
4. In the exitButton’s Click event, add code to end the program.

Step 5 – Create a splash screen

Create a splash screen using the Project menu - Add Windows Form. Select the Splash Screen form template.

Also change the splash window title to "Internet Cafe". reference : textbook page 114.

Set project properties:

Set the project’s startup form to be MainForm.   Set the project’s splash screen to be SplashScreen.

Step 6: Save and run

Save all files, then start the application. Try entering data and using the Calculate button. Is the result formatted as currency?

Wireless communication decision

1. 1-paragraph intro
2. 1-paragraph talking about how IoT connects and shares data.
3. I would expand on maybe 2 or 3 methods.

wifi

bluetooth

LPWAN

4. I would close out by saying why wifi. basically its cheap and easy to use and widely supported. I included some websites that have some useful info. I would just paraphrase some of that stuff.

have an intro paragraph where you briefly talk about the ESP 8266 NodeMCU.
