Answer:
2 3 and last one
Explanation:
Design a base class, Road, with the following members:
.
Attributes for storing the road's name, number of lanes, and maximum speed limit.
A three-parameter constructor to initialize the three attributes
Accessors and Mutators (Gets and Sets) for each attribute.
Input Validation: You should ensure that the number of lanes is always a value greater
than 0, and that the maximum speed limit is a value between 0 and 100 MPH. This input
validation should apply to both the 3-parameter constructor and the individual accessor
functions
A display function that prints the road's information in a single line format
Design a derived class, TollRoad, which inherits from Road. It should have the following members:
.
An attribute for storing the toll for using the road.
A 4-parameter constructor to initialize the three attributes of the base class, as well as
the toll
Accessor and Mutator methods for the toll.
Input Validation: You should ensure that the toll is a value greater than 0.0. This validation
should apply to both the 4-parameter constructor as well as the individual accessor
An overridden display function that displays the information of the TollRoad in a two-line
format, where the first line displays basic Road information, and a second line specifies
the current toll
I've attached my Java implementation.
C#
1. Create a new class called StandardSale
2. Add three private fields to the class:
_salesDate, a DateTime
_amount, a double
_quantity, an integer
3. Also, add properties with get and set accessors for each field, call them SalesDate, Amount, and Quantity.
In the "set" accessors, use if/else to limit Amount and Quantity to positive values and
to limit SalesDate to dates on or after 1/1/2000.
Use "else" to set Quantity and Amount to 0 and SalesDate to 1/1/2000 if the input values are invalid.
4. Add a constructor so that all three fields can be populated when a StandardSale object is instantiated.
5. Add a method called TotalSale that returns _amount * _quantity as a double.

Compare and contrast data warehouse and big data storage environments. Discuss the purpose, the data, the need for more than one BI data environment, whether these environments are complementary or competitive, and processing tools and methods used in the environments. Also include other items as you see fit. (15 points)
Answer:
The responses to the given question can be defined as follows:
Explanation:
The database engine is a large data store gathered from a wide range of sources within about an undertaking or Old to inform management decisions.
We study the database system and big data reasonably Information storage of Big Data is applied to the difficulty of storing data.
Big Data is a new term used to identify datasets due to the size and complexity. A database server is a given database category.
They are used to store huge quantities of data, such as analysis, historic or consumer data, but instead produce large reports and mines.
In the database system, the complexity of unstructured data is sung easily.
The challenge of big data is one of the most exciting opportunities for those decades to come.
A database server is a centralized relation server, where all the attractive data from different systems is gathered together.
They must wash and structure your data at the position of insertion before placing them inside a warehouse. This process is usually alluded to as ETL Extract, Transform, and Load.
The solution to the database system is helpful as the next step is clean and quick Big data and the data warehouse could only be a strong team to gain a strong range of new application scenarios.
However, they have to find a couple of changes to existing infrastructure, tools, and processes and incorporate large amounts of data into your existing world.
Its university and IT industry paid too much attention to Big Data.
Digital data is created or stored inside the computer world at a pace that exceeds the boundary range rapidly.
Upwards of two billion people were connected to the Internet globally. And more than five billion people own mobile telephones.
By 2020, the Internet typically connects 50 milliards of computers.
It will then be 44 times the predicted data output in 2009.
The information is transferred to the optical fiber and shared at supersonic speeds.
The amount of data, as well as the pace of the industry growth, increases because the information is transferred or exchanged at light speed on optical fiber and network devices.

Identify the correct syntax used to write to a text file. a. file = open('My_data.txt', 'w') file.write('This file contains data') b. file = open('My_data.txt', 'w') file.write(100) c. file = open('My_data.txt', 'w') file.write([100, 200, 300]) d. file = open('My_data.txt', 'a') file.write(['hello', 'hi', 'hey'])
Answer:
file = open('My_data.txt', 'w')
file.write('This file contains data')
Explanation:
Required
The correct syntax to write to file
From the question, we understand that we are to write to file and not append to the file.
This implies that the access mode will be w which stands for write
The first line of (a), (b) and (c) is correct.
(d) is incorrect
Solving further,
Only values of type string (i.e. str) can be written to file
With this, we can conclude that:
(a) is correct because 'This file contains data' is of type string
(b) and (c) are incorrect because, in (b), the value is of type integer and in (c), the type is list

When parameters are passed between the calling code and the called function, formal and actual parameters are matched by: a.
Answer:
their relative positions in the parameter and argument lists.
Explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
A parameter can be defined as a value that must be passed into a function, subroutine or procedure when it is called.
Generally, when parameters are passed between a calling code and the called function, formal and actual parameters are usually matched by their relative positions in the parameter and argument lists.
A formal parameter is simply an identifier declared in a method so as to represent the value that is being passed by a caller into the method.
An actual parameter refers to the actual value that is being passed by a caller into the method i.e the variables or values that are passed while a function is being called.
Write a function nexthour that receives one integer argument, which is an hour of the day, and returns the next hour. This assumes a 12-hour clock; so, for example, the next hour
after 12 would be 1. Here are two examples of calling this function:
>> fprintf('The next hour will be %d.\n',nexthour(3))The next hour will be 4.>> fprintf('The next hour will be %d.\n',nexthour(12))The next hour will be 1.
Answer:
The function in C is as follows:
int nexthour(int tme){
tme = tme%12 + 1;
return tme;
}
Explanation:
This defines the function
int nexthour(int tme){
Ths calculates the next hour using % operator
tme = tme%12 + 1;
This returns the next hour
return tme;
}
Write a class named Employee that has private data members for an employee's name, ID_number, salary, and email_address. It should have an init method that takes four values and uses them to initialize the data members. It should have get methods named get_name, get_ID_number, get_salary, and get_email_address. Write a separate function (not part of the Employee class) named make_employee_dict that takes as parameters a list of names, a list of ID numbers, a list of salaries and a list of email addresses (which are all the same length). The function should take the first value of each list and use them to create an Employee object. It should do the same with the second value of each list, etc. to the end of the lists. As it creates these objects, it should add them to a dictionary, where the key is the ID number and the value for that key is the whole Employee object. The function should return the resulting dictionary. For example, it could be used l
Solution :
class Employee:
#Define the
#constructor.
def __[tex]$\text{init}$[/tex]__([tex]$\text{self, nam}e$[/tex], ID_number, [tex]$\text{salary}$[/tex], email):
#Set the values of
#the data members of the class.
[tex]$\text{self.nam}e$[/tex] = name
[tex]$\text{self.ID}$[/tex]_number = ID_number
[tex]$\text{self.salary}$[/tex] = salary
self.email_address = email
#Define the function
#make_employee_dict().
def make_employee_dict(list_names, list_ID, list_salary, list_email):
#Define the dictionary
#to store the results.
employee_dict = {}
#Store the length
#of the list.
list_len = len(list_ID)
#Run the loop to
#traverse the list.
for i in range(list_len):
#Access the lists to
#get the required details.
name = list_names[i]
id_num = list_ID[i]
salary = list_salary[i]
email = list_email[i]
#Define the employee
#object and store
#it in the dictionary.
employee_dict[id_num] = Employee(name, id_num, salary, email)
#Return the
#resultant dictionary.
return employee_dict

Develop a program working as a soda vending machine. The program should show the product menu with price and take user input for product number, quantity and pay amount. The output should show the total sale price including tax and the change. Organize the program with 4 functions and call them in main() based on the requirements.
Answer:
Explanation:
The following vending machine program is written in Python. It creates various functions to checkItems, check cash, check stock, calculate refund etc. It calls all the necessary functions inside the main() function. The output can be seen in the attached picture below.
class Item:
def __init__(self, name, price, stock):
self.name = name
self.price = price
self.stock = stock
def updateStock(self, stock):
self.stock = stock
def buyFromStock(self):
if self.stock == 0:
# raise not item exception
pass
self.stock -= 1
class VendingMachine:
def __init__(self):
self.amount = 0
self.items = []
def addItem(self, item):
self.items.append(item)
def showItems(self):
print('Items in Vending Machine \n----------------')
for item in self.items:
if item.stock == 0:
self.items.remove(item)
for item in self.items:
print(item.name, item.price)
print('----------------\n')
def addCash(self, money):
self.amount = self.amount + money
def buyItem(self, item):
if self.amount < item.price:
print('You can\'t but this item. Insert more coins.')
else:
self.amount -= item.price
item.buyFromStock()
print('You chose ' +item.name)
print('Cash remaining: ' + str(self.amount))
def containsItem(self, wanted):
ret = False
for item in self.items:
if item.name == wanted:
ret = True
break
return ret
def getItem(self, wanted):
ret = None
for item in self.items:
if item.name == wanted:
ret = item
break
return ret
def insertAmountForItem(self, item):
price = item.price
while self.amount < price:
self.amount = self.amount + float(input('insert ' + str(price - self.amount) + ': '))
def calcRefund(self):
if self.amount > 0:
print(self.amount + " refunded.")
self.amount = 0
print('Thank you!\n')
def main():
machine = VendingMachine()
item1 = Item('Kit Kat', 1.5, 2)
item2 = Item('Potato Chips', 1.75, 1)
item3 = Item('Snickers', 2.0, 3)
item4 = Item('Gum', 0.50, 1)

The smalled valid zip code is 00501. The largest valid zip code is 89049. A program asks the user to enter a zip code and stores it in zip as an integer. So a zip code of 07307 would be stored as 7307. This means the smallest integer value allowed in zip is 501 and the largest integer value allowed in zip is 89049. Write a while loop that looks for BAD zip code values and asks the user for another zip code in that case. The loop will continue to execute as long as the user enters bad zip codes. Once they enter a good zip code the progam will display Thank you. The first line of code that asks for the zip code is below. You don't have to write this line, only the loop that comes after it.
Answer:
The program in Python is as follows:
zipp = int(input("Zip Code: "))
while (zipp > 89049 or zipp < 501):
print("Bad zip code")
zipp = int(input("Zip Code: "))
print("Thank you")
Explanation:
This gets input for the zip code [The given first line is missing from the question. So I had to put mine]
zipp = int(input("Zip Code: "))
This loop is repeated until the user enters a zip code between 501 and 89049 (inclusive)
while (zipp > 89049 or zipp < 501):
This prints bad zip code
print("Bad zip code")
This gets input for another zip code
zipp = int(input("Zip Code: "))
This prints thank you when the loop is exited (i.e. when a valid zip code is entered)
print("Thank you")

Draw an ERD for the following problem with attributes, primary keys, cardinalities and participation constraints and specialization, if appropriate.
An information studies student wants to keep track of the following information. A publishers publishes two kinds of publications: books and journals. Any one publisher publishes at least one book and/or at least one journal. Each book can be written by one or more authors and one author can write one or more books. Each book and journal is characterized by one or more indexed keywords, which are represented by a keyword number and keyword. Not every keyword is used by the journals, however. Both books and journals have a unique number (such as ISBN# for a book and ISSN# for a journal), title and a publisher. For books, the student tracks the published year, all author information and their institutions. For journals, the student keeps the starting year first published, the number of issues to be published per year and the category of the journal (such as academic, newsletter, trade). Each publisher has name, address and phone.Each author has an ID number, name, address, phone, author's affiliated institution and the address of the institution. An author may be affiliated with more than one institution.The student would like to keep only authors who are participating in writing at least one book and institutions that have such authors.
Answer:
Following are the solution to the given question:
Explanation:
Ellipses are the attributes.Rectangle entities are shown.Rhombus is the relationship.The double rectangle is the weak entity.Is-A is a triangle relationship.There has to be N: N between books and authors because one writer can write one or more books, and one or more writers can read each book.
The N: N eigenvalues also exist among authors or students as Authors who participate in the creation of one or more books and organizations with these writers will keep their tracking of them.
