Using the program below, explain what the output will be at LINE A. 1 #include 2#include 3#include 4 5 int value - 128; 6 7 int
slega [8]

Answer:

This is the complete correct program:

#include <stdio.h>

#include<sys/types.h>

#include<unistd.h>

int value = 128;

int main()

{

  pid_t pid;

  pid=fork();

  if (pid==0) /* child process */

  {

  value +=8;

  return 0; }

  else if (pid > 0) {/* parent process */

 wait (NULL);

 printf ("PARENT: value =%d\n" ,value); /* LINEA */

 return 0;

}

}

The output of the LINE A is:

PARENT: value = 128

Explanation:

The fork() function used in the program creates a new process and this process is the child process. The child process is same as the original process having its own address space or memory.

In the child process the value of pid is 0. So the if condition checks if pid==0. Then the child process adds 8 to the value of its variable according to the following statement  

value +=8;

Now the original process has value = 128. In else if part the parents process has the value of pid greater than zero and this portion of the program is of the parent process :

else if (pid > 0)

{ wait (NULL);

printf ("PARENT: value =%d\n" ,value);

return 0; }

So the value 128 is printed at the end in the output.

wait(NULL) is used to wait for the child process to terminate so the parent process waits untill child process completes.

So the conclusion is that even if the value of the variable pid is changed in the child process but it will not affect the value in the variable of the parent process.

Explain how Steve Jobs created and introduced the iPhone and iPad.
Natali5045456 [20]

Answer:Today, we're introducing three revolutionary products. The first one is a widescreen iPod with touch controls. The second is a revolutionary mobile phone. And the third is a breakthrough Internet communications device. So, three things: a widescreen iPod with touch controls, a revolutionary mobile phone, and a breakthrough Internet communications device. An iPod, a phone, and an Internet communicator. An iPod, a phone...are you getting it? These are not three separate devices. This is one device. And we are calling it iPhone. Today, Apple is going to reinvent the phone.

Late last year, former Apple engineer Andy Grignon, who was in charge of the radios on the original iPhone, gave behind-the-scenes look at how Apple patched together demos for the introduction, with Steve Jobs showing off developmental devices full of buggy software and hardware issues. The iPhone team knew that everything had to go just right for the live iPhone demos to succeed, and they did, turning the smartphone industry on its head even as Apple continue to scramble to finish work on the iPhone.

Apple had actually been interested first in developing a tablet known as "Safari Pad", but as noted by a number of sources including Steve Jobs himself, the company shifted gears once it became clear how revolutionary the multi-touch interface developed for the tablet could be for a smartphone. Apple's tablet wouldn't surface until the launch of the iPad in 2010, three years after the introduction of the iPhone.

Seven years after the famous Macworld 2007 keynote, the iPhone has seen significant enhancements in every area, but the original iPhone remains recognizable as Apple has maintained the overall look of a sleek design with a larger touchscreen and a single round home button on the face of the device.
