Write the proghrams for the following:

belka [17]

Answer:

#include <iostream>

using namespace std;

int main() {

bool a,b,c;

cin>>a>>b;

if(a^b)//X-OR operator in C++.

c=true;

else

c=false;

cout<<c;

return 0;

}

#include <iostream>

using namespace std;

int main() {

bool a,b,c,d;

cin>>a>>b>>c;

if((a^b)^c)//X-OR operator in C++.

d=true;

else

d=false;

cout<<d;

return 0;

}

Explanation:

The above written programs are in C++.There is an operator (^) called X-OR operator in C++.It returns true if the number of 1's are odd and returns false if the number of 1's are even.

In the if statement I have user X-OR operator(^) to find the result and storing the result in another boolean variable in both the questions.

The camera on a phone or laptop can be used to track a user's eye movements. Which of these is NOT one of the possible applicati

AnnyKZ [126]

Answer:

The question is incomplete. The full question is the following one:

"The camera on a phone or laptop can be used to track a user's eye movements. Which of these is NOT one of the possible applications of this technology (as listed in the course reading):

All of these ARE:

Measuring the user's intelligence,

Gathering marketing information for advertisers,

Detecting cognitive disorders."

The correct answer is: "Measuring the user's intelligence".

Explanation:

This technology is also known as eye tracking technology and has to do with a sensor that tracks eye movement and interaction with machines, such as mobiles and computers. The only option which does not apply to this technology and its features is the first one, "Measuring the user's intelligence", because "intelligence" is very subjective and abstract, it is not something a sensor can measure, although eye tracking technology can measure the amount of production concerning certain topics, the level of interest, attention, and interaction, and some cognitive disorders people behave, such as Attention Deficit Hyperactivity Disorder (ADHD). Besides that, companies, agencies, and institutional systems may track and gather people's eye movements in order to share them with other companies, agencies, and institutions for improving marketing, production, and interests.

Write a program that (a) generates a vector with 20 random integer elements with integers between -29 and 30, (b) replaces all t

Ghella [55]

Answer:

import random

randomlist = []

for i in range(0,20):

n = random.randint(-29,30)

if n < 0 :

n = 100

randomlist.append(n)

print(randomlist)

Explanation:

The random module is first imported as it takes care of random. Number generation.

An empty list called randomliay is created to hold the generated random integers.

Using a for loop, we specify the range of random numbers we want.

Inside the for loop ; we attach our generated random integer which will be in the range (-29 to 30) in a variable n

For each n value generated, if the value is less than 0( it is negative, since all the values are integers), replace the value with 100.

List the three control problems associated with competingprocesses and briefly define each.

hjlf

Answer and explanation :

the three control problems associated with competing process are

MUTUAL EXCLUSION : We know that some resources are shareable and some are not shareable. which means only one process can access the resource at a time this type of resources are called critical resources this code can be access at only one process at a time. the other process if required to access should not be allowed
DEADLOCK: this hold the process without complete for example suppose there are two resources R1 and R2 and two process P1 and P2 and P1 use R1 and P2 use R2 but after some time when P1 needs R2 but R2 is not available as it is used by P2 so the all process will be on hold
STARVATION : when priorities are given to the process as high priorities and low priorities. And high priorities process always competing then low priorities process have to wait for very long time this is called starvation
