*C PROGRAMMING*

Create a program which requires the computer to guess the user's number from 1-100. The user does not need to enter their number at any point. The computer should just guess a random number, and then the user can choose whether or not the number is too high or too low, and if the computer does not guess the correct number, it will will keep guessing and eliminate the values from the range that is either too high or too low (depending on the user's selection after a guess is made).

EXAMPLE OF PROGRAM LOGIC:

num = 38 (user's selection - not actual input)

1 to 100 (high and low variables initialized)

computer guess 50 (guess determined by 1 + 100 / 2)
high (user says the number is too high)

49 (new high value - if high subtract 1 from guess and store in high)
computer guess 25 (guess determined by 1 + 49 / 2)
low (user)

26 (new low value - if low add 1 to guess and store in low)
computer guess 38 (guess determined by 26 + 50 / 2)
Correct! (user)

I need to have someone design a website using

• Code one JavaScript server application using Node.js for routing, Express.jsfor framework and Handlebars.js for templating
• Necessary npm modules are: express, express-handlebars, path and body-parser

- it willl have a drop down box with 5 names of titles of a picture.

- highlite 1 name in dropdown box and there is a select button to make web site go to that picture stored on server..

this is my third question on this site and i have yet to receive any help. so I really need help on this now because i am so far behind

The following program calls the fork() system call to create a child process.

Suppose that the actual pids of the parent process and child process are as follows:

Parent process: 801

Child process:   802 (as returned by fork)

Assume all supporting libraries have been included.

=> Use the answer text field to write the values of the pids printed at lines 1, 2, 3, and 4 (indicate each line number and the value printed).

int main()

{

     pid_t pid, pid1;

     pid = fork(); /* fork a child process */

     if (pid < 0) {

          fprintf(stderr, "Error creating child.\n");

          exit(-1);

     }

     else if (pid > 0) {

          wait(NULL); /* move off the ready queue */

          pid1 = getpid();

          printf(pid); /* Line 1 */

          printf(pid1); /* Line 2 */

     }

     else {

          pid1 = getpid();

          printf(pid); /* Line 3 */

          printf(pid1); /* Line 4 */

     }

     return 0;

}

Privacy and Security

The purpose of this exercise is to review the privacy and security policies of a web site.   Pick a commercial web site (one that sells a product online), locate the privacy policy and the security policy, and read both.   Complete the Web Analysis form and provide the following information:

• Provide a summary of the privacy policy.   What did you find comforting about the policy?   What did you find in the policy that concerns you?

• Provide a summary of the security policy.

• Opinion:   Are these policies defined to protect you, the consumer, or YOU, the business?   Explain your answer.

Implement the constructor, accessor (getter) and mutator (setter) methods indicated in the comments below for the following class Player.

public class PlayerTester
{
public static void main(String[] args)
{
Player p = new Player("John Adam");
p.addScore(70);
p.addScore(80);
System.out.println("Average score is " + p.averageScore());
}
}

public class Player
{
private String name;
private double totalScore;
private int gamesPlayed;

//constructor with one parameter for the player name - 2 points

//Three accessor methods: getName(), getTotalScore(), getGamesPlayed() - 2 points each

//One mutator method: addScore(double) - 2 points

public double averageScore()
{
double avg = totalScore / gamesPlayed;
return avg;
}
}

I need new and unique answers, please. (Use your own words, don't copy and paste), Please Use your keyboard (Don't use handwriting) Thank you...

Let us say we are given the task of building an automated taxi. Define the constraints. What are the inputs? What is the output? How can we communicate with the passenger? Do we need to communicate with the other automated taxis, that is, do we need a “language”?

An operating system uses the Round Robin (RR) without priority CPU scheduling algorithm, with a quantum = 4.

Consider the following set of processes in this OS, with the length of the CPU burst time given in milliseconds, and the shown priority.

The processes are assumed to have arrived in the order P1, P2, P3, P4, P5, all at time 0.

a) Draw a Gantt chart illustrating the order of execution of these processes, showing their completion times.

b) Calculate each process’ waiting time, and then compute the average waiting time for this set.

Note:  waiting time = completion time – arrival time – burst time

Given the following business scenario, create a Crow’s Foot ERD using a specialization hierarchy (EER) if appropriate.

Two-Bit Drilling Company keeps information on employees and their insurance dependents. Each employee has an employee number, name, date of hire, and title. If an employee is a full-time inspector, then the date of certification, the renewal date for that certification, and the yearly salary should also be recorded in the system. If an employee is a part-time inspector, then the date of certification, the renewal date for that certification, and the hourly wage should also be recorded in the system. For all employees, the Social Security number and dependent names should be kept. All dependents must be associated with one and only one employee. Some employees will not have dependents, while others will have many dependents.

Imagine we have two possibilities: We can scan and email the image, or we can use an optical character reader (OCR) and send the text file. Discuss the advantage and disadvantages of the two approaches in a comparative manner. When would one be preferable over the other?
