Answer:
MAP_SHARED
Explanation:
The MAP_SHARED should be included in the 4th argument of map. When we have a MAP_SHARED set, then we have it that it is preserved across a fork2 system call.
It is visible immediately in every parent, siblings or child processes. This is to say that any change that is made to this mapping is immediately seen by readers.
I need help with my homework:
Greetings, secret agent 00111! Your mission, should you choose to accept it, is to help Agent M plan a pizza party. Unfortunately, M has no idea how much pizza to order for his 83 guests. Luck for him, party planning is your specialty! Estimate the number of pizzas he’ll need on scratch paper, and then convert that number to binary and write it here.
Answer:
You need to order 11100 pizzas.
Explanation:
A couple of assumptions here.
Each pizza has 12 slices. Each guest will eat 4 slices (1/3 of a pizza).
83 * 1/3 = 28 pizzas
28 = 11100

Non-blocking code does not prevent execution from continuing while blocking code prevents execution from continuing until the operation is complete. Blocking calls hold off on returning until the I/O operation is finished. Synchronous results are returned from it.
What is the difference between blocking calls and non-blocking calls?Blocking calls hold off on returning until the I/O operation is finished. Synchronous results are returned from it. During the waiting period, nothing else in that process happens. In contrast, a non-blocking call uses a different method to check for completion and returns right away without any results.
Non-blocking code does not prevent execution from continuing while blocking code prevents execution from continuing until the operation is complete. Blocking occurs when subsequent JavaScript in the Node. js process needs to wait until a non-JavaScript activity is finished, according to the documentation for the language.
A program that is non-blocking does not prevent the execution of subsequent operations. Non-blocking techniques run in an asynchronous fashion. Asynchronously refers to the possibility that the program may not always run line by line.

Write an if-else statement for the following:
If user_tickets is less than 5, assign 1 to num_tickets. Else, assign user_tickets to num_tickets.
In python 3.8:
if user_tickets < 5:
num_tickets = 1
else:
num_tickets = user_tickets
For this code to work properly, you'll have to first declare user_tickets before the if-else statements.

Write a function named power that accepts two parameters containing integer values (x and n, in that order) and recursively calculates and returns the value of x to the nth power.
Answer:
Following are the code to the given question:
int power(int x, int n)//defining a method power that accepts two integer parameters
{
if (n == 0)//defining if block to check n equal to 0
{
return 1; //return value 1
}
else//defining else block
{
x = x * power(x, --n); //use x variable to call method recursively
}
return x; //return x value
}
Explanation:
In the above-given code, a method power is defined that accepts two integer variable in its parameter, in the method a conditional statement is used which can be defined as follows:
In the if block, it checks "n" value, which is equal to 0. if the condition is true it will return value 1.In the else block, an integer variable x is defined that calls the method recursively and return x value.Write code that will read the contents of umich_buildings.json and load its value into the gobal variable umich_buildings.

salvado has a flash disk of 1.5GB and wants to store more music files of 950KBs each . How many files will he be able to store on his flash disk?
Answer:
Convert 1.5GB to KBs = 1500000kb
1500000kb/950kb ≈ 1579
Explanation:
A flash disk is a storage device. It has enough memory to store large files. In the given question, the flash disk has a memory of 1.5GB and can store 1578.94 music files of 950KBs each.
What is flash disk?A flash disk is a data storage device that uses flash memory specifically : a small rectangular device which is designed to be plugged directly into a USB port on a computer. It is often used for transferring files from one computer to another computer system.
Flash disks have no mechanical platters or access arms. It is termed "disk" because of the data which are accessed as if they were on a hard drive. The disk storage structure is emulated.
In the given question, the flash disk contains 1.5GB memory and has to store music files of 950KBs each. For determining the number of music files which can be stored in the flash disks, we have to first convert the unit of flash disk from GB to KB:
1GB = 1,000,000 KB
1.5 GB = 1,500,000 KB
size of music file = 950 KB
Number of music files that can be stored = storage in the flash disk ÷ size of the music file
Number of music files = 1500000KB ÷ 950KB
Number of music files = 1578.94

Explanation:
in pycharm, write a program that prompts the user for their name and age. your program should then tell the user the year they were born. here is a sample execution of the program what is your name? Amanda how old are you? 15. This is what I have so far but I can't get pycharm to tell me the year I was born.
import datetime
name = input("What is your name? ")
age = input("How old are you? ")
year = datetime.datetime.now().year
print("Hello ' + name + ' you were born in " (year - age))
Let's address the few mistakes in your code so far. First, age is of type string and year is of type int. You're trying to subtract an int by a string and that doesn't work. Also, you have inconsistent quotes "Hello '. You should always use the same type of quote. The (year - age)) isn't properly formatted into the print statement. There is no plus adding it.
Here's my working code:
import datetime
name = input("What is your name? ")
age = int(input("How old are you? "))
year = datetime.datetime.now().year
print("Hello " + name + " you were born in " + str((year - age)))
I just fixed your code. Best of luck.
In python, date and time seem to be not its type of data, but the date and time named module can be imported for it to work with the time and date. So, the program and its description can be defined as follows:
Program Explanation:
Importing "datetime" package.Defining two-variable "name, age" in which we input value from user-end.Defining another variable "year" that holds current year value.In the next step, the print method has used that prints the user name with the born year.Program:
import datetime#import package datetime
name = input("What is your name? ")#defining a variable name that uses an inputs method to input string value
age = int(input("How old are you? "))#defining a variable age that uses an inputs method with the int to input value
year = datetime.datetime.now().year#defining a variable year that takes current value in it
print("Hello " + name + " you were born in " + str((year - age)))#defining a print method that print name value with born year

Explanation:
Analyzing the given code segment
In class Dance,
A method named dance was defined with an instance of two string variables/values
which are name and song
public Dance(String name, String s)
In the main of the program,
The first line creates an instance of Dance as dance1
dance1 is initialized with the following string values: "Tango","Hernandos Hideaway"
- The first string value "Tango" will be passed into the name variable of the Dance method
- The second string value "Hernandos Hideaway" will be passed into the song variable of the Dance method
Next, another instance of Dance is initialized as dance2
dance2 is initialized with the following string values: "Swing","Hound Dog"
- The first string value "Swing" will be passed into the name variable of the Dance method
- The second string value "Hound Dog" will be passed into the song variable of the Dance method
On line 3 of the main: System.out.println(dance1.toString());
The values of dance1, which are "Tango","Hernandos Hideaway" are printed
On line 4 of the main: System.out.println(dance2.toString());
The values of dance1, which are "Swing","Hound Dog" are printed
Hence, option d answers the question
