A.

Program Plan Intro

Given code:

//Include the necessary header files

#include <stdio.h>

#include "csapp.h"

//Define a main()

int main()

{

//Initialize the variable x as 1

int x=1;

//Check the condition

if(fork()==0)

//Print the statement

printf("p1: x=%d\n", ++x);

//Print the statement

printf("p2: x=%d\n", --x);

//Exit

exit(0);

}

Explanation:

The given code is used to print the output of the child and parent processes.

In the given code, the main program initializes the variable “x” as “1”.

The “if” condition check, function “fork()” is equal to zero.

Condition is true, print the value of “x” by incrementing “1”. So, the value of “x” becomes “2”.

Otherwise, print the value of “x” by decrementing “1”. So, the value of “x” becomes “1”.

Exit from the program.
