3. Write a program that prompts the user to input an integer that represents cents. The program will then calculate the smallest combination of coins that the user has. For example, 27 cents is 1 quarter, 0 nickle, and 2 pennies. That is 27=1*25+0*5+2*1.

Answers

Answer:

The program in Python is as follows:

cents = int(input("Cents: "))

qtr = int(cents/25)

cents = cents -qtr * 25

nkl = int(cents/5)

pny = cents -nkl * 5

print(qtr,"quarters,",nkl,"nickels,",pny,"pennies")

Explanation:

This gets input for cents

cents = int(input("Cents: "))

This calculates the quarters in cents

qtr = int(cents/25)

This gets the remaining cents

cents = cents -qtr * 25

This calculates the nickel in remaining cents

nkl = int(cents/5)

This calculates the pennies in remaining cents

pny = cents -nkl * 5

This prints the required output

print(qtr,"quarters,",nkl,"nickels,",pny,"pennies")

Write a program get_price.py with a function get_price() that takes a dictionary of fruits as an argument and returns the name of the most expensive fruit. Each item of the dictionary includes: A key: the name of the fruit A value: the price of the fruit.

Answers

Answer:

The program is as follows:

def get_price(fruits):

   AllPrice = fruits.values()

   value_iterator = iter(AllPrice)

   mostExpensive = next(value_iterator)  

   for item in fruits:

       if fruits[item]>=mostExpensive:

           mostExpensive = fruits[item]

           fruitName = item

   print(fruitName)

fruits = {}

n = int(input("Number of Fruits: "))

for i in range(n):

   name = input("Fruit name: ")

   price = int(input("Fruit price: "))

   fruits[name] = price

get_price(fruits)

Explanation:

This defines the get_price function

def get_price(fruits):

This gets all price in the dictionary fruit

   AllPrice = fruits.values()

This passes the values to a value iterator

   value_iterator = iter(AllPrice)

This initializes mostExpensive to the first price in the dictionary

   mostExpensive = next(value_iterator)

This iterates through the elements of the dictionary  

   for item in fruits:

If current element is greater than or equals most expensive

       if fruits[item]>=mostExpensive:

Set most expensive to the current element

           mostExpensive = fruits[item]

Get the corresponding fruit name

           fruitName = item

Print fruit name

   print(fruitName)

The main begins here

This initializes the fruit dictionary

fruits = {}

This gets input for the number of fruits

n = int(input("Number of Fruits: "))

This is repeated for every inputs

for i in range(n):

Get fruit name

   name = input("Fruit name: ")

Get fruit price

   price = int(input("Fruit price: "))

Append name and price to dictionary

   fruits[name] = price

Call the get_price function

get_price(fruits)

Give examples of applications that access files by each of the following methods:
+ Sequentially.
+ Random.

Answers

Answer:

Explanation:

Usually, applications would have the capability of using either one of these options. But for the sake of the question here are some that usually prefer one method over the other.

Any program that targets an API usually uses Sequential access. This is because API's contain all of the data as objects. Therefore, you need to access that object and sequentially navigate that object to the desired information in order to access the data required.

A music application would have access to an entire folder of music. If the user chooses to set the application to randomly play music from that folder, then the application will use a Random Access method to randomly choose the music file to load every time that a song finishes.

When you try to hit the jackpot over the night and send thousands of connection requests in 24 hours, LinkedIn will know you’re using bots or tools and they will block you, temporarily or permanently.    

This is clearly against the rules of LinkedIn. It cracks down against all spammers because spamming is a big ‘NO’ on LinkedIn.    

What people do is that they send thousands of connection requests and that too with the same old spammy templates, “I see we have many common connections, I’d like to add you to my network.”    

It will only create spam.    

The LinkedIn algorithm is very advanced and it can easily detect that you’re using a bot or LinkedIn automation tool and you’ll be called out on it.

b. CIDR address format represents a Class C network only used within an intranet.
c. Subnet masks are used with both class and classless IP addresses.
d. all statements are correct.

Answers

Yeah the answer is b

Subnet masks are used with both class and classless IP addresses is the correct statement. Therefore, the correct option is C.

What is an IP address?

A device on the internet or a local network may be identified by its IP address, which is a special address. The rules defining the format of data delivered over the internet or a local network are known as “Internet Protocol,” or IP.

Only C is correct, rest other statements are incorrect because:

a. IPv4 and IPv6 addressing is fully compatible with one another is incorrect. While IPv4 and IPv6 can coexist on the same network, they are not fully compatible with one another.

b. CIDR address format represents a Class C network only used within an intranet is incorrect. Classless Inter-Domain Routing (CIDR) is a technique used to allocate IP addresses more efficiently.

Therefore, subnet masks are used with both class and classless IP addresses is the correct statement. Therefore, the correct option is C.

Pollution is the introduction of harmful substances into the environment that can cause damage and harm to humans, animals, and the environment. It takes on a number of different forms, from chemicals and garbage to something as seemingly innocent as light or noise. Pollution comes from a variety of sources. In addition, it alters, changes, and even destroys a variety of places. For example, exhaust from cars pollutes the air. When it rains, runoff from fertilizers and pesticides, which farmers use to help crops grow, can pollute the water in oceans, rivers, lakes, and streams. Garbage dumped in landfills is not only an eyesore, but also a source of harmful gases that can damage the earths atmosphere. Light pollution, which comes in the form of bright streetlights or signs, disrupts the view of the night sky. Noise pollution caused by cars, trucks, and machines interrupts the natural sounds of the world around us, such as birds singing or leaves rustling. The types of pollution and their effects vary greatly. At the same time, however, they are related; each type of pollution affects the other types. An example of the connection between different types of pollution is acid rain. Acid rain is caused mostly by sulfur or nitrogen emissions given off by sources such as car exhaust and the burning of fossil fuels such as coal. These harmful chemicals rise into the atmosphere where they react with other compounds and then fall as an acidic form of rain, sleet, or snow. Acid rain damages plants and buildings, contaminates soil and water, and has a negative effect on animals, fish, and even humans. Pollution has other effects, too. Breathing toxic air or drinking polluted water can cause humans and animals to develop health problems that can be serious and sometimes deadly. The deaths of too many members of a certain species of animal can upset the local ecosystem, or the area in which they live. As a result, weather patterns and climates can also change. Though pollution is everywhere, there are ways to help prevent it. By walking or riding bikesinstead of driving carspeople can help decrease air pollution. People can also buy and eat organic foods to support farmers that do not use fertilizers on their crops. It is also a good idea to take old things that people intend to throw away and find new ways to use them. A great way to help the environment is to recycle. Save items like used paper, glass and plastic bottles, and metal cans. Then, take them to a recycling center where they can be turned into new products to be used again. Some cities and towns even have recycling programs in place so all you have to do is leave your recyclable items on the curb on a certain day each week.
