Program Explanation:
Include header file.Defining the main method.Defining an integer variable "n, i", after defining this use "n" to the input value.In the next step, a loop is declared that uses if block that checks fork value equal to 0, in which it calls the sleep method and prints its value.At the last, it calls the wait method.Program:
#include<stdio.h>//header file
#include<sys/types.h>
#include<sys/wait.h>
#include<unistd.h>
int main()//defining the main method
{
int n,i;//defining an integer variable
printf("Enter the number of child to be created:"); //print message
scanf("%d", &n);//input value in n
for(i=0;i<n;i++) // defining a loop that use if block with the frok method to print value
{
if(fork() == 0)//use if that check fork method value equal to 0
{
sleep(3);//calling sleep method
printf("[child] pid %d from [parent] pid %d\n",getpid(),getppid());//print message
}
}
wait(NULL);//calling wait method
return 0;
}

A sample member of the list data is a1 = ['male', True] where the second item is True if the person is on the phone.
for item in data:
if item[0] == 'male':
males = males + 1
if item[___
]:
malesOnPhone = malesOnPhone + 1
Choices are 1, 2, 3. Answer is for if item[___]:
Answers
0
Explanation:
In the lists, indexation starts from 0, because of that in if statement we compare item[0] which is 'male' and 'male', and then males is itterated within for loop.
Three steps can be taken to construct a list of elements using a for loop: Make an empty list appear. Iterate through an iterable or set of elements. Add each component to the list's end.
What loop for sample member of the list data?An Array List can be looped through using an Iterator. If there are additional members in the Array List, the method hasNext() returns true; otherwise, it returns false. If there is no next element, the method next() raises the No Such Element Exception and returns the next element in the Array List.
FOR LOOPS and WHILE LOOPS are two popular types of loops. A For loop runs a variable number of times. LOOP TYPE — FOR LOOP When you know how many times you want to run an algorithm before stopping, you use for loops.
Therefore, Since indexation in lists begins at 0, we must compare item[0], which is “male,” with “male” in the if statement before iterating through males in the for loop.

The necessary things that should be done to avoid a project scope creep include documenting the project requirements and setting up change control processes.
The scope of a project simply means the work that is required in order to complete a project. On the other hand, project scope creep means the occurrence that happens when changes are made to the scope without a change request.

You are given an array of integers. Your task is to create pairs of them, such that every created pair has the same sum. This sum is not specified, but the number of created pairs should be the maximum possible. Each array element may belong to one pair only.
Write a function
class Solution public int
solution (int[] A); }
that, given an array A consisting of N integers, returns the maximum possible number of pairs with the same sum.
Examples:
1. Given A = [1, 9, 8, 100, 2], the function should return 2. The pairs are (A[0]. A[1]) and (A[2], A[4]); the sum of each pair is 10.
2. Given A = [2, 2, 2, 3], the function should return 1. Although, for instance, A[0]+A[1] = A[0]+A[2], the pairs (A[0], A[1]) and (A[0], A[2]) cannot exist at the same time, because they both contain a common element, A[0].

At what layer in the TCP/IP protocol hierarchy could a firewall be placed to filter incoming traffic by means of:
a) message content
b) source address
c) type of application
Answers
The answer is c) type of application
The most significant protocol at layer 3, often known as the network layer, is the Internet Protocol, or IP.The IP protocol, the industry standard for packet routing among interconnected networks, is the source of the Internet's name. Thus, option C is correct.
What are the TCP/IP protocol hierarchy could a firewall?Application-layer firewalls operate at the TCP/IP stack's application level (all browser traffic, or all telnet or ftp traffic, for example), and thus have the ability to intercept any packets going to or from an application. They stop different packets (usually dropping them without acknowledgment to the sender).
Firewalls are frequently positioned at a network's edge. An external interface is the one that is located outside the network, while an internal interface is the one that is located inside the firewall.
Therefore, The terms “unprotected” and “protected,” respectively, are sometimes used to describe these two interfaces.
